Q: 100% Disk System Disk Usage with only 0.1 MB/s

I am encountering a problem that is crippling my laptop. Over the past weekend I have been expierencing my laptop coming down to a standstill in processes it takes nearly two minutes to open up a page on chrome and running a game... forget about it. When I open up task manager it shows that 100% of my disk is being used but when I look at the processes using it all I see is System 0.1 MB/s. When i go into the performance tab of task manager and click on disk it reads:

Active time: 100%
Average Response Time: 0 ms then it spikes to a random # in the thosands
Read Speed: 0 KB/s (Like the Response time it jumps around)
Write Speed: 0 KB/s (Same as above)

Preferred Solution: 100% Disk System Disk Usage with only 0.1 MB/s

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: 100% Disk System Disk Usage with only 0.1 MB/s

Exactly the same problem - Acer Aspire One.
I was having performance problems and ran chkdsk which found some bad clusters. Next thing I know, I restart and Windows won't come up. I could get a cmd prompt going and copied out my files and reset the system. Still nothing. Finally got it going by turning it on and plugging in a recovery flash drive. Completely reinistalled 8.0. Installed 126 updates. Installed 8.1. Installed 26 updates. And now I'm smack in the 100% disk usage.
Tried setting Virtual Memory, which was small.

This sounds straight forward, but I can not figure this out I am new to this. I have a Etower 500 MHz with 192 mb's of memory and 4 gig hard drive. I used partition magic 3.5 to partition the drive inorder to try and install DOS and win98 and maybe linux. I am following the instructions from this web site here>> http://www.xperts.co.za/multi-boot/ I am using the disks that I made from downloading from this site referring to REUEL Boot disk this disk took me through the entire process. It all went great until I rebooted and I keep getting Non-System disk or disk error I have no disk's in the drives. I even installed win98 and all it did was go straight to windows. With in windows I could see the drives I partitioned all of them except the one that windows was actually on. I have done this again and again trying to see if I did anything wrong. Anybody know what is wrong?
Also can anyone tell me how to get free dos I can not figure out what files to download. The one that I am trying to install now is suppose to be mini dos 6.22. I am really new to dos so I am doing a lot of guessing.

I'm here to ask for an advice for this new issue occurred with my vaio.
A recently made a system refresh for fixing some other bugs but after this my PC became extremely slow.
Everything seems to go in the right way in refresh, no errors, no blocks, nothing wrong at all.
This issue is related to disk usage that in prompt is always very high, always greater than 90%, normally capped at 100%.
What is using my disk are 2 processes of windows, not 3rd part softwares: system and another processo including lots of windows functions.
I googled this and found a lot of people having same problem and, according to those threads:
1 i tried to disable windows search from services
2 no driver issues, my PC came out with w8 and i never updated them, so drivers are the same I had before the system refresh
3 avg installed now, but also before refresh and never gave problema
4 no bloatware, malware or viruses. After refresh I uninstalled a lot of Sony bleeps but I think this bug was there Aldo before uninstall, I simply thought that slow was related with those software, it wasnt.
Any ideas? Any system scan to post?
Thanks for reading and help,

Yesterday I tried to do a system restore to fix a Flash Player problem but I did not have restore points going back as far I wanted. I only had 3 Scheduled system restore point going back to March 23rd and 8 restores points done by Revo and various Flash Player install/unsintall restore point created while trying to fix said problem. I thought those 8 restore points might have deleted older scheduled ones but my maximum space hasn't been reached yet and I did not turn off system restore.

From what I read online, I have a crazy amount of space allocated to shadow storage so I was curious as to why I did not have more system points to choose from. Any ideas? Is there anything that can delete restore point besides turn system restore off?
Used 33 GB
Allocated 35GB
Maximum 87GB

Also when I went to select the disk to restore it said
Partition_1(C:) (system) Ready to restore
(Partition_1(C:) The disk cannot be found
I have two disks Partition_1 (C:) and Recovery (D:) which is the factory restore stuff and is locked so I don?t create points for this one.

The Partition_1(C:) (Missing) shows in the available disks in system protection. Should I just uncheck it?

A:System Restore Disk Space Usage and System Recovery

Hello pineapplegrunt.

Do you regularly run programs such as CCLeaner and/or Disk Cleanup? It is possible to delete restore points with these tools (and other similar ones).

I believe your problem is that System Restore points are automatically deleted, by default, after 90 days.

I believe there are ways to change this, although from the top of my head I think you have to use a third party application (to do this easily). However, it is not really recommended to keep such long system restore points, if you want an image of your drive going that far back, you probably should look into creating a backup image or something and not relying on system restore.

Can I ask what your flash player problem is, have you been able to fix that?

This issue has been happening for a while now. This is my "gaming laptop" and I currently
only play WoW. Yet even with my settings turned as low as I can get them my computer halts, stalls and completely freezes. 

I've noticed that my computer NEVER goes above 50% disk usage. Almost as if its capped at 50%. And when it reaches 50% is when my
problems begin. Normally these programs have most of the usage when it randomly starts freezing at 50%.
- svchost.exe Service Host: Local System (Network Restricted)

- svchost.exe Service Host: Local Service (Network Restricted)
- IAStorIcon.exe IAStorIcon (32 bit)

I guess my issue is why is my disk usage capped to 50% and how do I fix this so it can utilizes all 100% ?

For the last week or so my system has been very slow to startup, and during this time the disk shows at 100% usage.
It takes at least 5-10 minutes until everything has loaded and disk usage returns to normal and the system is usable.

I have checked the resource monitor and there is nothing specific that is thrashing the disk, the top apps consuming most I/O changes as the system starts.
I have uninstalled McAfee to rule that out.
If I start in safe mode, then everything is fine.
I have tried stopping certain services which I have read are common culprits, such as superfetch and shadow copy, but it had no effect.

A:100% DISK usage causing slow system startup

if you start in safe mode and everything is fine, then please try this. Open msconfig– click on the services tab– check the box hide all Microsoft services– note which services are checked and then uncheck them all – restart your PC and if everything runs fine do the following steps.
Open msconfig – go to the services tab – check the box hide all Microsoft services – check half of the services you had unchecked – restart. By doing this process a few times you will identify the offending service.

A few weeks back, my C: drive started mysteriously filling up to the point where it was running out of space completely.
I would run CCleaner, organize things, clean out my downloads folder, and in some cases even delete some of the games I hadn't played in a while to make more room. A couple days would go by and it would be filling up again!
I finally figured out that my System Protection maximum disk usage was set to 50%, and Windows 7 was graciously creating many restore points every time I made any sort of change to my system (removing a game, for instance or installing a new one) and it was filling up my hard drive quickly.
I don't know how this got set to 50%, I certainly didn't do it as I didn't even know this existed. It is supposed to be 10% by default.
I changed it to 10% and deleted the old restore points. Things were back to normal for about a week, and then I noticed it was filling up again.
I just not checked it, and it was set back to 50% again! I changed it back down to 5% and again deleted the old restore points.
I have run Malwarebytes' Anti-Malware, and I have run a full scan using Avast! Free, and I have run a full scan using Spybot Search & Destroy, and none of these have caught the culprit. Could anyone help diagnose why my system protection settings keep getting changed to 50% maximum disk space being available for system restore points? I would like to set this to 5% or 10% and have it stay there... Read more

A:System protection maximum disk usage changing itself to 50%

The easiest (and best) solution is to completely disable system restore and begin using disc imaging software on a regular basis instead. It's more reliable, all encompassing, and infinitely better protection.

Hi everyone. I am currently having issues trying to diagnose the system and compressed memory bug that causes slow disk operations. I am running a computer that I have built myself. i5 6600k, 16 GB of RAM, 2 SSD and 1 HDD. The slow operations only happen on the HDD. I can notice this when folders start to become slow and playing saved videos start to lag and drop frames. I can copy these videos and watch them just fine on the SSDs without any lag at all. I have tried multiple fixes such as disabling the notifications from windows and One Drive does not seem to be installed on my computer. I have also tried all of the solutions here BEST FIX: 100% Disk Usage by ?System and Compressed Memory? in Windows 10 - Appuals.com I just tried the second one now so I'm not sure if that's going to work. I'm just a little worried that disabling the second one will have some kind of negative impact on my computer. I also have the same symptoms as the user suggested fix as mentioned in that link, but I am not sure how to go about changing the settings like they did.

It is also worth noting that this hard drive is from a previous laptop that I put into my desktop. The system boots off of one of the SSDs and the HDD that is slow is side drive. I have tried repairing and checking the integrity of the system files, defragging the drive which I thought would help, but did not. None of the services I ran reported any problems including chkdsk.

A:System and compressed memory high disk usage

Hi, if you search the forum for
system and compressed memory

you will find useful information in several threads. It may not be easy or quick to resolve. Solutions are different for different users. This was much discussed about a year ago- hardly any reports recently.

Given that, I would suggest you manually update to the AU build from1511.
Windows 10 ISO Download - Windows 10 Forums
Take due precautions, and create full disk images before you do so e.g. using Macrium Reflect (free) 0 disk images are strongly recommended here.

Why? People sometimes find the upgrade fails and their PC is unbootable, or they experience widely reported new issues with the AU esp. on older hardware. So your disk images (which you can then use routinely as good practice) can save you.

Could you please add your Win 10 build and Pro/Home to your specs.

Hey everyone,

So I've been fairly busy lately, and just recently started using my laptop again. It runs 64-bit Windows 10 and on startup, the system seems to be somewhat sluggish but nothing alarming. Once everything boots up, the system runs at what I would consider a normal speed. I noticed the system fan making more noise than usual and opened the task manager to find that 100% of the disk is being used. I have done the following things based on what I found through google:

Turned off the "Show Me Tips About Windows" feature
Quit Skype
Currently running a virus scan

What puzzles me is that it appears that most other people who encounter this issue experience a system wide slowdown after the machine boots, but I do not have this issue. I am hesitant to disable Superfetch as I do not fully understand what it does and it appeared to be more of a fix for users with a SSD, whereas I have an HDD. To go along with the disk usage, my battery life seems to have diminished, however I attribute this to the disk usage.

I haven't posted here in a long time, and have forgotten how to submit a machine log or system stat log. I can post one later if it would help.

Thanks in advance. I really appreciate the help and insight.

My laptop (Lenovo Y500 Laptop | Lenovo US) has a 1TB 5400rpm hard drive C: and it also has a 24GB chached SSD D:. The link only shows a 16, but mine was 24. Today, I left my computer idle while I was at class (I'm in college) and when I came back it was frozen on the start up screen Lenovo Logo. As customary with computer problems, I turned it off and turned it on again. It booted up fine, maybe the tiniest bit slow, but nothing really different from the norm. But, when I opened up Chrome, my entire computer froze up after about five seconds, and I had to force shut down. This happened about 10 times (not just with Chrome, but with explorer and Task Manager too). Weird thing is, I only got one BSOD, for MEMORY_MANAGEMENT. When it magically started up without immediately freezing after the first click, I scanned for viruses--nothing changed. I CCleaned the temp files and registry--still nothing. I checked for fragmentation--0% fragmented. Once I finally got Task Manager open, I started thoroughly checking all the tabs. Here's what I found:

I have had some problems in the last few days where playing youtube videos or netflix was very very choppy.

I looked into these performance issues and in order to avoid standard responses: I cleared my browser cache and clean up my flash player junk with Ccleaner as well.

Doing some observation of my task manager quickly gave me an answer to my problem: System and compressed memory would constantly use about 50% of my HDD capacity and especially when a new webpage is opened or a new program is started on my computer, it would peak to over 80% for this process with total overall HDD usage at 99%. This is what causes my videos to be very choppy, especially in the beginning.

I have no clue what to do with this or what causes this process togo bazerk like this. Does it have to do with power settings? I tried changing from high performance to balanced or energy saving, but that doesn't do much at all. Doesit have to do with recent tweaks in my Nvidia control panel to optimize my GPU performance for certain games? A quick look at my current global GPU settings say that it's all pretty default at the moment. I also changed from Norton 360 to Avast internet security lately, though I reckon it las little to do with it (i'm just desperate for answers lol)

The internet provides no answers, so I hope you guys could enlighten me.

Thank you for WindowsSeven forums. I have just registered but during the last 6 months or so I have used the resources provided here - particularly the tutorials - to set up my Wndows Home Premium x64 system.

Looking at one of the tutorials: System Protection Restore Points - Delete
I have a couple of questions I hope someone can help me with.

Options 3 and 4 of the tutorial cover deleting system restore points selectively with CCleaner or System Restore Explorer.

My questions about doing such selective deletions of restore points with these utilities are:
1. Does it actually save any disk space; or is it simply cleaning up a list so that after the deletion of unneeded ones only the restore points considered useful are presented in the list - whereas system restore disk usage is left unaffected.
2. Is there any risk in deleting restore points at various arbitrary points; are they interdependent? Will deleting some cause a risk of others not working?

Essentially, if it is possible, I would like to keep restore points done at the begiining (after drivers, windows updates and installation of programs etc.) and delete the remaining ones except the most recent one - but I only want to do this to save significant disk space by the selective deletion.

Thank you.

A:Deleting System Restore Points Selectively - disk usage

Deleting the points does recover disk space. You can see it with
WinDirStat - Windows Directory Statistics

You can use this shortcut to make restore points with your comment

System Restore Point Shortcut

Makes it easier to know what happened. For instance before installing a program I may use it and comment "before installing zappos untried newsreader" or whatever.

I would not only rely on restore points. I've heard a thorough disk defrag can mess them up. It's good to also image your system to an external drive. You can find free imaging programs.
There's a list here:

Free Hard Disk Backup and Restore, Hard Disk Image and Cloning Utilities (thefreecountry.com)

But you may find some additional if you search the Software sub-forum on thiis forum.

Hey there, so I've just been looking at my old desktop PC and i was looking into the system restore settings and seen that 12% of disc space is reserved for restore points. i've changed this 10% now as the PC barely gets any use anyway, will that be ok? (Equates to about 10GB)
I also noticed that my 2nd hard drive was enabled for system restore... However, this drive only has media on it, no programs, no operating system nothing, just music files.  Now my question is, can i use this drive for system restore points even though the OS is not installed on it? The Reason I ask is because i have a lot more free space on this drive...  If not, should I just go ahead and disable monitoring on that drive?
Any help would be greatly appreciated.

A:System restore disk space usage and using on a 2nd hard drive?

First of all yes, 10% is fine. Second, system restore keeps it's files in a hidden folder named "System Volume Information", and there is one of those folders on each drive on which System Restore is enabled. Last, the system restore points for any given drive MUST be stored on that drive.
Personally, I'd suggest disabling system restore completely and using disc imaging software instead.

If I open Settings in Windows 10, then go to System > Storage, I get the following usage for C:
161Gb used of 285Gb
whereas File Explorer gives the more sensible 21Gb used of 145Gb, which is almost certainly the correct values, given that it is a 145Gb partition, and is a fresh install of Windows 10. The C: partition is on a 480Gb SSD drive.

Here is a screenshot of disk management showing the correct values

And here is a screenshot of the Storage screen with the incorrect values

Can anyone explain why this is?


A:Incorrect disk usage values displayed in Settings > System > Storage

The C: drive partition is correctly identified as 145.70GB, however if you add up the rest of the partitions without drive letters (ie) 139.70GB + the hidden 350MB and 450MB partitions, you get 285GB not including the 160GB of Unallocated Space. Since the other partitions don't have drive letters, System/Storage is lumping those drives into the total capacity of C:.

System has over the last several months continued to slow down.  IE after booting up will sometimes open, but will quickly hang with not responding message or restarting message.  When this occurs, the system slows to the point that no other programs will be usable.  if I wait long enough, it appears to have short restarts, but eventually I need to reboot.  Sometimes it is so bad need to do the "power button" reboot.
Downloaded Firefox to see if that helps, but same issue.  Reset IE to default and that appeared to help for a short period.(minutes, not days).
I note that the HD light flashes almost solid during the hang periods.  It seems like something is thrashing.  I check the disk and it does not appear to be fragmented.
When I run in safe mode, which I needed to do to get this post sent, everything appears to run normally.
Below is the output from FRST program.
Thank you in advance

When I upgraded to Windows 7, I bought a new mobo, graphics card, etc... I installed Windows 7 on a new 128GB SSD drive (C: ), and then pulled my old 1TB drive with Windows XP on it from my old machine and installed it as D:.

When I try to go to "Backup and Restore", and click "Create a system image", Backup and Restore misidentifies my old 1TB drive as a System disk, so I can't create a backup on it, and Windows demands that it be part of the backup, even though it's mostly just documents on this drive (there are some programs installed on this drive - Steam and Microsoft Flight - is having software installed to this drive enough to make Windows think it's a system drive?)

I've already marked the D: drive as "inactive", deleted D:\Windows and all the cruft associated with it (pagefile.sys, etc...). Disk Management shows C: as "Boot, Page File, Crash Dump, Primary Partition", and shows the "System Reserved" partition on the same drive (the D: drive wasn't plugged in when I installed Windows 7.) Disk Management shows D: as "Primary Partition", and that's it.

diskpart "details disk" shows this for D:

Hi, I left my Pc on standby last night, there were no signs that the computer was broken in any way. I started it up by hitting one of the keyboard keys and it came up with a blue screen of death which I didn't take note of. After I restarted my pc and now it looks like it can't find the OS. I have tried to system restore but it won't let me. And I have also tried choosing a system image backup but it still won't let me. Any help will be highly appreciated.



A:Disk boot failure on startup, insert system disk and press enter

Hello Kyle!

What kind of boot drive do you have? What model is it? Is there another storage device in your PC?

Start your PC up and check if you see the boot drive in BIOS. If not, power down the PC, open it up change the cables and port, start up again.

Good luck!

hello everybody here at B.C

As this topic mentions this is supposed to be a BIOS guide, not exactly tho....
I will write about what i have encountered and worked with when it comes to this motherboard in hope to expand this knowledge and hopefully finding a solution with a broader network.

As mentioned this is the ABIT AN8 Fatal1ty S939 Motherboard without the SLI = double PCI EXPRESS installed
Basically my old motherboard stopped functioning so i had to replace it with the Abit Fatal1ty, at first i was very pleased becouse i read alot of positive stuff about it, altho i dont really like too much advertising this motherboard looked promising.
A part of the horror that struck me was that i needed to install WinXp from start, there were reports of users who could simply do a repair of winxp so they wont loose any valuable data, but in my case i didnt have that option, my windows could not be saved. Since i had 3 HDD's i plugged in another one after backing it up from another pc, becouse i simply mistook it for the hdd that had winxo on it, anyway i thought to myself i could backup my winxp containing drive at a later state when i get winxp installed on the drive i just cleaned. I then instaled all the hardware where it belongs and booted up and put in the WinXp SP2 cd and ran thru the first part of the setup ( where the files get copied over to your hdd before the restart )
All went well and the pc gave me as usual a 15 second timline to restart or it would do it by its... Read more

A:Bios's ( Disk Boot Error Please Insert System Disk And Press Enter )

Simply put, the disk that you think that you are booting from, and the disk that you are booting from, are not the same. I did the same thing myself not too long ago. Pull out the other disks and install XP. Once it is working, then install the other hard drives. If you are sure that you are booting from the same drive on which XP is installed, then the disk is thrashed.
You said you took out a disk from another system and it booted fine. How about trying this? Take the disk out of your system that you think is the one with XP on it, and see if if it will boot the other machine?
This is no huge mystery. It can only be one of very few things.

I just downloaded Windows XP(Service pack 3) and mounted it to a USB disc.

Problem is, it doesnt work. On the boot screen it gives me the message invalid system disk. replace disk and press any key to continue and then when i press any key, it boots into my hard drive/Windows 8.

Originally i thought something was wrong with the boot but now i think it may or may not be. All help is highly appreciated.

A:Unable to boot, invalid system disk. replace disk and press any key to continue

Few, if any, downloadable copies of WinXP are legal. The 'Invalid System Disk' error message is the tip off.

You'll need to buy a copy from an authorized source. There is no way to trick the system into recognizing an illegal copy of Windows.

Hi i have a self built pentium 4 pc that wont boot.
When i turn it on there is a very long wait at the HP Invent screen (it is a ms 6577 ver 2.1 board) and when it finally gets to the black screen with the slashing dash in the top left hand corner it just flashes for around a minute before saying "DISK BOOT FAILURE. INSERT SYSTEM DISK AND PRESS ENTER"
I have managed to get it to boot once by going into the recovery tool on the XP disk and using "FIXBOOT" but that only worked once and it wont work any more. The specs of the pc are,

PENTIUM 4 1.8GHZ 478
MS 6577 VER 2.1 BOARD
256 MB RAM

There is nothing to lose on this PC. Thanks in advance. Alex

Well, as some of you may jnow, this pc has caused me a lot of trouble. So, now its installed witha brand new Motherboard, RAM, AGP card, and hardDrive.

Installed Windows 2000 using the upgrade disk, popping in Win98 to confirm I had it. It all worked okay, but on a restart the error comes up:

Boot from CD: Disk Boot Failure, Insert System Disk and Press Enter

Now, in the BIOS, I've had the boot sequence as all sorts. First, was

CDROM, HDD-0, Floppy

No joy, so went to

HDD-0, CDRom, floppy


Floppy, HDD-0, CDROM

Then, for the sheer heck of it

HDD-0, HDD-1, Floppy

Still nothing.

I tried it with Quick Boot disabled, nothing. Seek Floppy is Enabled, was disabled by defalut. HDD S.M.A.R.T is enabled, was disabled by default.

As the pc at home is the only one there, I can only answer via the work's pc during the day. I have my motherboard booklet, and the BIOS is Phoenix AwardBIOS

Any help would be great, so close to marking the threads that I've started on this problem Solved

Thanks in advance

Help. I just built a new computer and I don't know what's going on. I keep getting the error: disk boot failure, insert system disk and press enter

Here's my scoop:
-All new parts: IBM 30GB 7200rpm, P3 800EB, Aopen AX3S pro,128mb ram, 52x standard cd, standard floppy.
-Boot sequence = a,c
-I am trying to use a win98 boot disk (tried 2)
-followed my motherboard's instructions exactly
-CMOS and POST detect everything successfully

Everything checks out. What else is there? Could it be that my hard disk is dead???? A brand new Disk????

Thank you,

Ok, I built a PC a month ago and everything seemed find no problems of any sort. The other night I defragmented my hard drive and shut it down and turned it on today to a memory test and the message "Disk Boot Failure, Insert system Disk and press enter"

The computer has access to the XP pro w/ sp2 disk only as a boot device but it will not recognize it now.

I have set Cd-rom as 1st for boot sequence then hard drive I have no floppy drive and the bios has been configured to know that.

I am not sure if this means anything but in the bios the IDE Channel 0 Master says none and when I try to turn on auto detection it wont detect a hard drive.

The HDD is fully connected and has not been touched since I installed it a month ago.

I have this awful feeling that I fried the HDD when I defragmented it last night.

Any help would be very much appreciated. But please be simple this is my first build and my knowledge at this sort of thing is very very sketchy at best.

I have installed a new hard drive and used three different sata cables none of that worked. I have even taken out the battery and that did not work. I am about to give up and scape the whole thing.

I have just moved house and my computer has been in storage for 6 months. I've just set up the PC and when I've come to turn the computer on it says "Disk Boot Failure, Insert System Disk and Press Enter". I have a Packard Bell computer with Windows Vista Home Premium installed but wasn't given a System Disk as this was pre-installed onto the computer. I suppose if I could log into the computer I would be able to run some kind of system restore but I can't get past the "Disk Boot Failure" screen.

I've made a recovery CD from the internet but when I've put this in the CD drive and even selected the BIOS setup to go to the CD drive first it doesn't boot the recovery disk.

When I click on F8 when booting it doesn't give me the option of booting from Safe Mode it just shows a list of bootable drives.

A:Disk Boot Failure, Insert System Disk problem - Windows Vista

Two things:

1. Check your cable to your harddrive and from your harddrive to your motherboard and make sure it is securely attached.

2. If that isn't the problem then go into your BIOS and place your CD/DVD drive as First Bootable and see if you can now run that disk you made.

I'm trying to install a PC with Windows 7 threw USB (2.0). Therefore I've used Windows USB/DVD Tool.
To note, I've installed a NEW hard drive, the old one broke down due to it's age.

Now I'm getting the next message: DISK BOOT FAILURE, INSERT SYSTEM DISK.

I've tried setting the boot sequence but none of that helped, I keep getting the same message.

Thanks in advance,


A:Windows 7 Installation error DISK BOOT FAILURE, INSERT SYSTEM DISK

Normally means that the hard drive is not detected. Check its connections, plugged securely into SATA1 port with no others attached, data and power cable securely attached.

Then enter BIOS setup by tapping the key given for that on the first screen. Is the hard drive registering anywhere there? It often will be represented by its Serial Number.

Reset BIOS to defaults, set SATA controller to AHCI, Save settings and Exit.

Hi everyone,
This is my first post on this site, and i want to thank you for your responses in advance.

OK so here is my problem. I know that there have been posts on this topic becfore, however mine is different than the rest of the posts. In the other posts,this has occured on a modified computer, but when it happened to me, it was my unmodded computer. So heres what happened. I boot up, and after the HP screen, instead of going to the windows loading screen, I get a message with alot of text, but the main point was that "a failure was imenent", F1 to continue, F2 to enter setup. So i hit F1 to continue, and after a minute of a blank screen and the blinking text dash, the DISK BOOT FAIlURE, INSERT SYSTEM DISK message. But I have never modified my coputer, and never used a setup disk before on this machine. What do you advise I should do?
BTW:I tried resetting BIOS, but to no avail.

A:UNIQUE Disk Boot Faliure, Insert System Disk and press Enter

Recently, after unplugging my system from its power source (removing power cable from the power supply) and then later reconnecting the power source, the machine will not boot unless a Vista system disc is in the drive upon boot, mind you, not booting from the disc, just having it in the tray and booting to the OS harddrive. If the disc is not present at startup the machine displays the following error message:


If I insert the disc after this is displayed, the machine hangs and does nothing. If I restart my system after inserting the disc, the machine boots as normal.

Attempted fixes:

bootrec.exe /rebuildbcd, /fixboot

Operations complete successfully but they do not fix the problem. These actions were attempted primarily as a shot in the dark. Typically I have encountered this issue when the molex connector or other cabling is loose on the OS HDD, but that is obviously not the issue, since I am posting this from the machine.

OS is currently installed on an IDE drive, set as master on the primary IDE channel.

Any suggestions would be appreciated to save my the extra step in order to boot.

Repair MBR:

Boot From the Windows Install Disc
The first thing you?ll need to do is boot off the install disc, and then click through until you see the ?Repair your computer? link in the lower left-hand corner.
You?ll need to choose the correct installation of Windows and then click the Next button.
And then you?ll get to the System Recovery Options screen, where you can get to the Command Prompt.

Repairing the Master Boot Record:

If you want to restore the master boot record, you can simply type in the following command:

bootrec /fixmbr

You can also write a new boot sector onto the system partition with this command (which is often more useful):

bootrec /fixboot

And of course, if you just use bootrec /? you?ll be able to see all the options.

Hello everyone,

We have tried many things to get our computer running, and no luck. We have an older Pentium II 400 MHz computer, and we installed a brand new 500 GB IDE hard drive ( which is recognized at start-up ) and we have Windows XP to install. The computer will not install Windows, and the boot disk the hard drive manufacturer provided will not boot the computer.

We have been working on it for three nights and nothing!

We set the boot in BIOS to boot from CD, and it will not boot with Windows XP, or the hard drive CD that came from Western Digital. We even reset the bios, and took out the battery for over 5 minutes and no luck ( except that it helped the computer to finally recognize the new hard drive - we only have one which is set as the Primary Master. We checked all the cables, and disconected the main cables from behind the hard drive, and the two CD roms and nothing!

Can anyone please help us?
