Q: Missing Operating System/Error Loading Operating System

Hey all! I am pretty new to this kind of Win7 issues, so I hope some of you will be able to help. Story goes...

After few hours of gaming the computer died. (It happened right after switching keyboards.) Now, on every setup BIOS(?) comes up with list of options (F2 enter BIOS, F11 boot options, F6 Flash etc.). After that a black screen with error message comes up: Missing Operating System.

I tried rebooting from USB (since I have no disk-drive) and I keep on getting the answer: Error Loading Operating System.

Any ideas?


Preferred Solution: Missing Operating System/Error Loading Operating System

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.)

All unlikely, but possible - (a) your HDD died. (b) your bios became corrupted (c) your HDD boot sector became corrupted (d) your HDD partition is corrupted.

Does the drive spin up when you switch on (feel it)?
Check the bios to see if the HDD is reported correctly and is at the top of the boot order.
Find a bootable CD - an OS installer, or create Easeus partition manager bootable CD http://www.partition-tool.com/personal.htm and boot from it. What does the HDD look like with Easueus?

I'm trying to fix my friends Hp and I usually know what im doing. But here I have no idea what to do.

I tried going into the bios to change the boot order to cd to format and I can't. Can anyone tell me what to do.

-I changed out his hard drive with mine and it does nothing. just posts and goes to a black screen instead of trying to boot and blue screening as it usually do when you change hardrives between two computers

-Changed the Ide cables no luck.

Hi all,

Installed a DVDRW drive but comp crashed when installing some software and it stopped detecting my Primary Master and Slave drives. I've fiddled about with the Master and Slave configs and have managed to get it to detect my HD and DVDROM.

I've unplugged my DVDRW and my small HDD and am trying to get windows to load up.

After using FDISK /MBR an rebooting, I get "Missing Operating System".

Tried installing Windows XP after formatting, it seems to have installed but it's not loading.

Current config:

Slave: Pioneer DVDROM (not the DVDRW)
Master: Seagate 80GB (C: = 15GB) & (D: = 61GB).

D: has files on there that I'd like to recover. Too big to put on floppy.

I've run a search for similar problems and tried some of the solutions but no good. Any ideas? Thanks

then it says hit ctrl+alt+ delete to restart. and the thing is there is no operating system on it. and it says this whether or not a cd is in the cd/dvd drive. i have tried windows 7, and even my old windows xp disk and nothing. it isnt the same thing where you can repair it through the disk it doesnt give me that option just goes straight to that. and it restarts and does it all over again. I first tried to install through USB mode, that didnt work so i quick formatted the hdd on another computer, the hdd is a wdc 750 gb. the motherboard is a gigabyte m68mt-s2. now that i got a piece to make my old pata disk drive to a sata i could do disk. i have tried pulling the motherboard's battery out and putting it back in but nothing. any help would be much appreciated.

Sounds like hardware for sure. "Sounds" like .

Try one of these thorough hardware tests. Use the advanced options to test what you want. Avoid the "destructive" drive tests, of course, if you want to keep what you have on your drive.

Hello Saketis, welcome to the forum

This could be caused by a few things, have a look here it is old and out dated but the info is good (except the bit under the header "Corrupt boot files on the computer" you should ignore this paragraph) (and the boot order should be CD then HDD) Computer stops at verifying dmi pool data....

I have a Dell Latitude E6500 with no current OS. It was given to me ready for OS installation, in working order by an IS guy.  
The only problem was I didn't know how to install the OS.  I thought I would just follow the prompts.  So, I tried to install a Dell Reinstallation CD Windows XP Home Edition including Service Pack 1 CD.  However, I reached a point where it asked me a question in the process and I wasn't sure what to do so I aborted the process by removing the CD.  OOPS.

A few days later I decided to try and install Windows OS again, thinking when I got to that same question I would call a friend for advice. However, now when I put the CD in, I get the message Error loading operating system.  When I turned off the computer and turned it back on with the CD in the CD slot, it said Press any key to boot from CD.....Error loading operating system. But that's it.  No matter what key I press or how much I plead with it, it's not budging from this screen.
Any suggestions?  The computer was supposed to go on a plane to Central America with me Tuesday for a friend there and I really want to get it working so I can take it.
Appreciate any help.

Here's my story:

I have a Compaq Presario notebook on which I had two operating systems; Win XP (NTFS) and Red Hat 9 with GRUB loader. I used PM7 to delete all linux partitions and set win partition as active. after rebooting, Grub still went on, I loaded XP, PM made it changes (and looked like it crashed on some error) and after reboot I get message "Error loading operating system". Tried running recovery console from WinXP CD and running command fixmbr, but it doesn't help. When I try using fixboot, can't help. I can't boot from a floppy (USB floppy, even if I set it in BIOS - never worked for some reason).

I realize that I did a pretty stupid thing but I trust there is a way how to get over it. I would appreciate any help and hints...

A:error loading operating system

Ok, I fixed it myself this morning. Solution: I made a boot floppy with fdisk on it (actually for Win 98) and made a bootable CD from it. Started with CD, I ran fdisk /mbr and fixed the problem. After reboot, computer changed its message to "operating system missing", so I loaded Win XP install CD and did the repair. Afterwards it worked fine.

Hi, I've tried searching the forum, but nobody seems to have had the exact same problem as me.

I've had the same computer for 2 years now, one which I built myself, and until a couple of days ago, it's been fine.

However, it was starting to get a little slow, and so I looked on the internet for ideas on how to fix it.

I can't say for sure what caused the problem, because I did a few things. However, most was removing itunes from startup and the like (obviously I didn't stop any services that I shouldn't have) and the windows sidebar. The only thing that I hadn't done before was a service called error checking, and I also selected the scan and perform recovery of bad sectors bit.

Anyway, when I tried to boot again I got the message "error loading operating sytem."

I have tried changing boot settings in the BIOS, switching the hard drive that is used to load in case it was using the wrong one.

I saw a lot of people had success with fixboot and fixmbr with the vista disk. I have one, but can't load from it. I put it in and select to boot, get the press any key message, loading windows components, the bar loading, and then just a blank screen. I've left it for hours and still nothing happens.

This is driving me crazy, does anyone please have any idea what I could try?

A:Error Loading Operating System

Try booting in safe mode F8 during system post logo. If Windows loads go to start type in CMD in the command prompt

It is odd that the Windows disk does not work. Could be scratches on the disk. Is the disk a genuine copy?

I was attempting to load XP on a separate drive from my Vista machine. Booted in the XP CD, formatted and began the installation. After the setup files were copied to the other drive, the computer rebooted to finish the installation. Upon reboot, I got "Error loading operating system".

Reading further, I see that the mbr, boot sector and boot files were overwritten on my computer. I booted from my Vista DVD, navigated to the Boot directory, and issued "Bootsect.exe /NT60 All" at command prompt. Says it was successful. I reboot and still get the same error.

I also tried the automatic repair option. It didn't find any problems and didn't fix the error.

Booted again to command prompt from the Vista DVD. This time tried:
bootrec /FixMbr
bootrec /FixBoot
bootrec /RebuildBcd

When I issued last command, it said it was successful but # Windows installations found was 0.

Also did a chkdsk on my hard drive and came back clean. All files and directories are still present as well.

Rebooted and still getting the same error. What do I need to do?

I recently contracted a nasty virus on my office computer (via trojandropper). That computer is running on Win7. The virus messed with the MBR. In my effort to fix it, I connected the drive to my home computer (running XP Home) and ran an antivirus scan, which found plenty of infection but didn't solve the problem and also ran chkdsk, fixboot, fixmbr and bootcfg /repair.

Now my home computer is also broken. It won't boot to Windows. I get the message "error loading operating system". The drive is found in BIOS. The partition is found in chkdsk and bootcfg /repair which reports that it is repaired.

The drive looks fine if I slave it to another computer running XP. I also ran AVG and EASUS Partition Recovery 5.0.1 on the drive while it was slaved. Still no bueno.

I noticed that in diskpart the drive (a 320GB Seagate Barracuda) has 65MB of unformatted space. I tried to clear out that space by partitioning it, formatting it and then deleting the partition. It would not allow me to partition 1MB of the free space.

Finally, I tried Repair Install of XP, which recognized the old installation and completed fine, but the computer still won't boot to Windows and gives me the same error message.

Please help. I do not want to wipe the drive and start over.

how can i fix this?

A:Error loading operating system!

This is a tricky one - I had this problem with a computer in my house a while back, and had to reinstall. Firstly, you're going to need an XP install disk - if you got one with your computer, that should be fine (you don't need it yet, but just in case the following doesn't work). Also, your comp's specs and info would be very helpful.

1. Try to boot into Safe Mode - when the computer boots, as soon as you see your manufacturer's logo, press F8 or F12 (it depends on what make you have). Then, from that menu, hit 'boot into Safe Mode', or the text to that effect.

2. If safe mode fails, try booting into safe mode with command prompt - another option on that menu. It may hang at a certain DLL which could indicate a problem with that file. After you do those two things, we'll proceed.

Howdy all. I was hoping someone -- ANYONE -- could help me with what has become the bane of my existence!

Long story short, my first SATA drive, a Maxtor 6B250S0 died a few months after I got it, and was covered under warranty. Upon receiving the new drive, I wanted to GHOST (v10) the old EIDE ATA Drive onto the new SATA drive. The operation succeeded except I could not make the new SATA drive the system drive. I eventually gave up and decided to rebuild the system. I mention this only because I was able to successfully move all the contents of the old drive onto the new one (and I could access and manipulate the files, I just couldn't boot from the disk) -- the consistent problem was that after navigating the BIOS on boot up, I would receive "Error loading Operating System" when the OS should have taken over.

Now to my existing problem. Actually, the same problem. I have killed the existing partition and low-level reformatted the drive. After copying all of the XP files onto the hard drive, I'm getting the same error -- "Error loading operating system". Here is what I have tried in no particular order:

1. Fixboot
2. FixMBR
3. Tried using Maxtors MAXBLAST to establish the a full 250 GB partition (running original XP disks; not SP1 or SP2)
4. Tried utilizing standard 137 GB partition via XP
5. Removed all EIDE cables except those utilized for CD-ROM/DVD access

Does the BIOS actually try to boot from the drive? Maybe you have to tell it to boot from SATA? Did you perform the fixboot and fixmbr procedures with only the SATA drive attached too?

Last night I performed some extensive but fairly routine maintenance on my primary computer including running its complete anti virus scan, some anti spyware programs and Window's disk cleanup. I also installed some routine Windows updates and even rebooted to complete their installation.
All seemed well when I shut down the computer last night, but when I tried to turn it on this morning I got the following error message:

Error Loading Operating System

It seems unlikely that the HD itself is dead; It's a Seagate Barracuda 320 G SATA drive which is only a few months old. And given the file cleaning I did last night the timing of the error would seem wildly coincidental for a drive failure.

More likely is that in the process of cleaning files, the computer has lost the ablilty to detect it. Since the motherboard is older the drive is connected to the computer through a PCI controller card.

[ My intent was to upgrade the computer part by part last year. I bought a bigger hard drive that I needed and chose a SATA drive thinking that I would be upgrading the motherboard and processor before too long. That's been delayed somewhat but with the controller card the hard drive had performed flawlessly to date. ]

I am unable to use the Windows disk for a repair installation of the OS or to use the Recovery Console as this only leads to the message:

Although I didn't get a response, I was able to glean enough information from other similar posts to resolve my issue. In case something similar happens to anyone else this is what I did:
In reading one of the posts, I found that it was possible to install a third party SCSI RAID driver when booting to the Windows CD by pressing F6.

Although the manual for the controller card wasn't very helpful, the disk that came with it contained the necessary driver files. I was able to copy the files to a floppy drive from my backup computer and install it when using the Recovery Console.

At the C:> prompt I ran fixboot

And the problem was resolved immediately.

I rebooted the computer and it worked perfectly. Just has it had last night.

hi.. i've seen error loading operating system in my system. i've formatted the hard disk and installed xp os in it by keeping the hard disk in another system(second system's hard disk is replaced with the issue hard disk). now when i try to keep the issue hard disk in the original system and try to boot, it is showing "error loading operating system". i've tried changing the bios settings to default but same again. what is to be done now? how can i clear cmos memory? will that be helpful? how can i change to large or lba of access mode? i don't get that "access mode" in the bios setup.. help me getting the issue resolved...

A:error loading operating system

Hi Isaac. You can clear the CMOS memory by removing the battery (looks like a quarter) on the motherboard for a minute or two and then re-install it. Just pay attention to the polarity. Wiill it help? Hard to say. Will it hurt? Highly doubtful. You'll just have to set the information back up that you lost when you pulled the battery. Nothing major.

Does it give you any other error information or just that it has an error loading the OS? It almost sounds like your system is looking at an address location to start the OS but the address location isn't where your OS is.

Is this a new build, old HD w/fresh install, previously working computer now won't start? Is there important data on the HD? Where to start is in the bios, check to make sure the HD is being found and ID'd by the computer. Check the HD jumper and verify it is set to master. Since it boots off the CD and not off the HD and you can access it, download the diagnostic utility for your brand HD and run it. It's possible corrupt files on the HD are preventing the boot, but test the HD first for mechanical errors. Mike

If you use your laptop recovery CD's you will lose the lot in most cases as it reinstalls Windows and leaves the laptop as it left the factory. But you don't have them?

If you tried to use your Dell CD it will fail as the Dell CD will have all the Dell specific device drivers, and will likely be BIOS code locked to the Dell, so it will either refuse to even install (likely) or if it did install the laptop would be borked as all device drivers would have the wrong code force fed and fail. All data would also be lost.

About now you should be considering dropping the HDD out of the laptop and attaching to an XP desktop via an adapter (2.5 to 3.5 IDE) or in an external USB case, to recover your data.

Data that only exists only on a HDD is data that you don't care about losing, as file systems or hard drives can corrupt or fail at any time with no warning. And they do.

You may have to get your Sony CD's or buy another copy of XP.

I really need help here. I am not very computer savvy so I'm completely lost at this point. When I turn my computer (Dell Dimension 8400 running Windows Media XP) on it looks as though it's going to start but then the dreaded blank screen stating "ERROR LOADING OPERATING SYSTEM". I read a bit in the forum that I may need a recovery disc, which never came with my Dell computer. I called Dell and they will not send me a recovery disc because I'm out of warranty, big surprise. Is there any way I can download it from the internet or is there something else I can do. I unfortunately have no back up CD. My priority is to keep all my programs, internet bookmarks and documents. If anyone has any ideas I would love to hear them. Remember I?m not that computer savvy so I?ll need very detailed instructions on what to do. Thanks to all.

Well, you could try...Follow the directions at How to Create a Bootable XP Recovery Console CD - http://www.bleepingcomputer.com/forums/t/276527/how-to-create-a-bootable-xp-recovery-console-cd/.Once that is done...follow the directions for How to use CHKDSK in the XP Recovery Console - http://pirules3.14.googlepages.com/recovery_console_chkdsk.If any error messages appear onscreen...write those down and post in your next reply.Do not exit after the chkdsk /r command completes.Type the command fixboot and hit Enter.When that completes...type exit and hit Enter.Typically...the error loading operating system indicates a failing hard drive, from what I see.Louis

I'm looking for solution for my friend's laptop using WinXP SP2. She keeps getting the "error loading operating system" when WinXP starts.
Does she need to format the whole harddisk to get things work again? is there any better solution as she does not want to lose anything on her harddisk if possible.

A:Error loading operating system

I guess you could just boot from the win xp cd and say 'repair previous installation', or if that doesn't work, just re-install windows (by booting from the cd again). Data on other partitions will not be lost - only you might need to format the partition you're installing xp in if you decide to do a reinstall.

Hey everyone, I am new here and have a huge problem with my computer. I have a gateway computer that is 2.5 year old. I am running Window XP home version. I have spyware by webroot, cox security suite, agv anti-virus. My computer has been working fine until this morning. I used the computer last night and everything worked fine. I shut the computer off went to bed. When I woke up this morning and turned it on and it runs for about 5 seconds and I get a black screen with the message "Error Loading Operating System". It does not bring up the gateway screen or anything before I get the error message. I have the XP disk if needed. Also everything on the computer is already backed up.

IF you can boot to Safe Mode, uninstall the printer software and reboot and see if it will boot normally.

Hey guys,...not sure if this is under the right forum but I'll post it here for now. Mods, if in the wrong forum, please relocate as you see fit.

Recently, I've been getting this msg "Error Loading Operating System" whenever I boot up my computer. I tried running a diagnostics, and the hard drive was detected and also passed. Do you guys any suggestions on how to fix this problem? Thank you in advance,

A:Error Loading Operating System

I think you were on the right track by testing the Hard Drive. You should immediately backup important data, and then try another diagnositic for confirmation.Go to the manufacturer's website and download their disk utility to check the hard drive out (this list is kind of old, some of the links may have changed): Fujitsu "FJDT" DOWNLOAD Works with fujitsu models only.
Hitachi / IBM - DFT "Drive Fitness Test" DOWNLOAD Works with all manufacturers.
Maxtor "Powermax" DOWNLOAD Works with all manufacturers.
Samsung "hutil" DOWNLOAD Compatability unknown.
Seagate "Seatools" DOWNLOAD Works with Seagate drives only.
Toshiba - N/A There are no tools available for Toshiba, but you may be able to use IBM or Maxtor's.
Western Digital "Data Lifeguard" DOWNLOAD Works with WD drives only.

I just got my new windows 2000 laptop at work. I was poking around in it to see what new stuff was on it, and decided to backup the hard drive...
Here's my problem.
1) I don't know what the program was that I was using. It said Do you want to take a snapshot of your hard drive?
I clicked yes.
2) It then said that it would reboot in DOS and continue taking a snapshot of my harddrive, and that it may take 2 hours to complete.
Again, I clicked OK.
3) It shut down and tried to reboot (in DOS, I guess) but I got an "error loading operating system" instead.
4) I don't have an ERD made yet.
5) I tried pressing f8 to go to the last known good config, but (of course) that only works with an OS.
6) I have no clue what to do next.

Welcome aboard, I see this is your first posting.

It sounds like you are able to recover and access Windows 2000, but cannot get the backup to work. Is that your problem? It sounds like a drive image utility which can be used for backup was installed but it is broken or damaged. Windows 2000 does not come with one. The two most popular ones are Norton Ghost and PowerQuest DriveImage. To fix the problem you would need to reinstall the utility that was installed.

I just installed vista onto my computer probably a few days ago and it was working fine. Before that I was trying to partition my hard drive so I can keep my windows xp files and use vista at the same time. well it erased the windows xp and didnt create the other partition so I was left to either installing a new xp or vista....I chose vista for some odd reason.....

but to my problem....

well yesterday I decided to stop being lazy and install xp in a different partition. so I booted the windows xp cd and created a new partition using it, it restarts but it doesnt continue the installation....so I tried to install it again but after it reboots it wouldnt continue. So then I tried to boot to vista and I get "error loading operating system"

I tried using ptedit to see if it was hidden but vista was active. So I decided that maybe deleting the partition would work so I deleted it and I still keep getting the same message.

any remedies?


btw I want it back because I have tons of important files on it.(so stupid shouldve just installed xp in the first place....)
thanks again!!!

Hi guys, Newbie here! i did join up to the forum about a year ago when i last had a problem with my PC but my account has been closed. I'm no expert but if someone guides me through something then i'll be ok.

Right can anyone help me? here goes: Basically my problem stemmed from disabling my gfx card to play an old game (destruction derby 2) as per usual making XP run in win 98 mode didnt run the game and after reading a few posts on other forum's i thought turning of my gfx card would do the trick.
anyway..................it didnt. the game did load but kept freezing up when starting a race, so i tried playing around with the pixels settings and re-started the PC. When the PC started the usual stuff came up when re-booting then the screen went black, windows was working because when i pressed enter the XP intro theme came on through my speakers. but nothing was there just a black screen. I have 2 ports for my monitor, one for my gfx card that i currently use and the other being my old onboard GFX, neither worked.

So i went into BIOS and had a tinker with the setting where you can change something to AGP or PCI, and i put the setting to optimal setting and saved it.

then when re-booting i get the message: ERROR LOADING OPERATING SYSTEM. even when i put the old setting back on in BIOS this message comes up. so then i tried to re-install XP by formatting the C: drive where XP is installed but when re-booting after formating the message ERROR LOAFDING OPERATING SYSTEM ...

Hi everyone!

Well as the title says, I got that message when booting. Actually it is a long story before i got that message so i'll try to sum it up. So, what i've done and what happened are as follows:

27 October 2012: I built my PC from a scratch.

three weeks ago: I began suspecting HDD failure because it is not detected in the bios frequently, failed short dst and long generic test in seatools for windows and began to make weird sounds (kind of a scratching or grinding noise, but I can't really describe it) only when booting or extracting .rar files.

two weeks ago : the problem with the bios was gone. But the sound retains.

1.5 - 1 week ago : the PC loads gadgets and some programs (that launch on startup ex. drivers, antivirus) a bit slower. I suspect the HDD is causing this because the other components are fine and my PC could play games in full HD. Windows explorer also crashes sometimes, and minecraft too.

Just YESTERDAY : I've had enough with constant explorer crashing and slow system, so I decided to open my HDD to check for hardware problems (It's a stupid move, i know) but I failed because after i opened the screw and tried to open the cover I can't because the cover is shut tight and prying it open wont work. Then i just put the HDD back together with the PC and booted, then magically an error status 0xc000000f appeared on my screen. I searched forums and run repairs from my installation disk but my OS is not listed. So i went on to the commant prompt and use... Read more

Hi I have been trying all day to dual boot using the tutorial and no success.
I have windows 7 install on my computer. I want to have windows xp.
Now I have shrink my hard drive so I have 2 partitions now. Ok the problem is When I boot xp I goto install on D:/ the new partition it then copies all the files to that hard drive all good so then it wants to restart which is normal.
Then When it reboots it will say error loading operating system or just nothing.
Then I cant even Run windows 7 I have to delete that partition on windows xp and then put windows 7 and repair startup and Im back on again. It has to do something with the boot loader or something because I reckon Its trying to do start windows 7 but there is xp trying to install it self. Im not sure but I think I have tried every idea.
I have tried 2 different cds of xp.

One day I booted my PC and got the error message

Verifying DMI Pool Data...
Error loading operating system.

I entered the BIOS (Mercury Motherboard) and chose the "Load Fail safe defaults settings" and XP booted successfully but when I'm choosing "Load optimized defaults", I get the same error message again.

A technician told me to run the system on fail safe defaults only as there is no need for optimized defaults but I was not satisfied. He told me that the HDD in which Windows is installed has some problem so I should either get the HDD changed or install Windows in another HDD. I just wanted another opinion from the TSF team on this matter. Please advice me.

A:Error loading Operating System

yes that would indicate a hdd problem.

go to command prompt and chkdsk /r and let chkdsk do its thing.

Also download the hard drive manufacturers diagnostic utility and run that.

If you have the xp disk put in the drive and from the run box type sfc/ scannow this will install any corrupt or missing windows files again.

It sounds like something in windows was corrupted. If you have a windows xp cd, try booting from cd and running recovery console. Here is a microsoft overview of how to use it.http://www.microsoft.com/resources/documen...e_overview.mspxIf you have trouble booting from cd, go into bios setup and change boot order to have cd drive ahead of hard drive.
