Q: Error loading operating operating system

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.

Any ideas

Preferred Solution: Error loading operating 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.)

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?


A:Missing Operating System/Error Loading Operating System

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?

Yesterday, I was working on the computer, and decided to give a quick restart, no previous problems, unusual noises or otherwise, but on reboot "error loading operating system"

I have tried to read previous posts on the internet and are either too technical for me or don't seem to apply, but this is what I have tried so far

BIOS does recognize the drive
Exchanged with another HD with working XP and works, but obviously wants me to reactivate copy
OEM Windows XP disc does load> setup> Drive C is unformatted, damaged, or formatted with incompatible file system with options to format or return to previous screen......and that where I decided to stop and ask the experts before I really mess something up...I did post on another site with no responses, so any help will be appreciated.
Since then I connected as an external and was able to determine the c: partition of the drive is unreadable, the D: is fine

Is there any way to recover C: and how did it happen???

My computer is a hodgepodge of parts, so not sure what to include
was using up to date Win XP
no recent hardware changes
to the best of my knowldge no untrusted software downloads
HD: Hitachi Deskstar 200GB

If you need anything else please let me know

I have an Asus laptop computer with Windows 7 and when I turn it on I get this message, "error loading operating system." Just those white letters on a black screen, nothing else. I have had the computer for about a year and a half, and have not recently loaded anything new onto it.

Hi guys, tired man here.

All was well... until an error message chose to appear every time I boot my pc.

"Error loading operating system"

I've tried switching from Auto to Large (no change), I've tried mounting my windows partition in linux (doesn't even work although is has before) and It's looking like im screwed for good.

Does anyone know anything that would help me?

The best solution would be actually loading the operating system, but if that's not possible then the next port of call would be somehow backing up files (read something about hooking it up as a slave to another machine?)

Well, thanks for taking your time to read. And hopefully one of you wizards can help me

Hello everyone!

I had Windows Vista on a WD Velociraptor (74GB). Then I got a WD Velociraptor (300GB) and put Windows 7 on it. So, two Operating Systems on two separate hard drives. Normally, after my BIOS screen, a menu loads asking if I want to boot Windows 7 or Windows Vista. Vista was the C drive, 7 was the F drive. It worked gloriously for several months. But now the pain has begun. The sound on my computer was very quiet one day. Everything seemed set correctly, so I decided to try a restart. During the restart, when it reached the black Windows 7 screen, it seemed to freeze. I restarted the computer again. After the BIOS screen, where I would normally be asked what OS I want, it instead says "Error Loading Operating System". And now that is the message I get every time I try to restart my computer.

-Both hard drives are listed by my BIOS.

-If I disconnect or disable only the 74GB drive, I get "Error Loading Operating System"

-If I disconnect or disable only the 300GB drive, I get "Error Loading Operating System"

-I have not been able to locate my Windows Vista CD yet (although I probably could if it were the likely solution)

-I located my Windows 7 CD. I booted from the disc with only the 300GB drive and CD drive enabled in the BIOS. I went to the "Repair your computer". In the System Recover Options screen, there are no operating systems listed. I don't have a system image to restore from, so I sele... Read more

So I have a dell inspiron 1720 laptop and I have gotten rid of vista. I have been using tiny xp and just recently decided to reformat after a virus bomb. I was going to particion my drive space so the OS would be in it's own part just in case it happened again I wouldn't have to lose some info. In the middle of the reformatting it lost power. When I try and start up the comp again it gives the error loading operating system message, and when I try to boot from the disk it gives the same message. So I can't continue formatting. I'm doing a diagnostics test right now to see what errors it gives. Is there anything anybody could think of to fix it? Any advice is much appreciated. Thanks.

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.

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.

I have a computer that got struck by lightning which fried the motherboard. In the process of waiting for a replacement motherboard I put the hard drive in another computer and did a window repair on it to get it running. I put in the new motherboard and needless to say it didn't work and all I had was a blinking underscore.

I tried a repair on the hard drive again this time in the same computer, nothing, I changed every part in the computer accept the motherboard still nothing, i've run chkdsk so many times its rediculous. I've written a new boot sector, and a new MBR. After doing all of this I get Error loading operating system when I try to boot the computer. I upgraded the bios still nothing. I can't lose whats on this hard drive no questions about it. I do have a backup of the hard drive which also doesn't work in the computer. When I put either the backup of the real on in the computer that I did the repair on it boots fine.

Any help would be appreciated

A:Error loading operating system

the easiest thing to do would be to install your questionable hard drive in a working computer in slave mode, assuming both are the same file format, or at least the removed drive isnt ntsf and the surrogate drive isnt fat32...
on the working computer, unplug the rom and use the power and ribbon cables for your hard drive, you probably will need to pin the hard drive in the slave position.
once that is achieved, copy your info via windows explorer.

on the bad computer, the motherboards would need to be the exact same model for the installation to work without loading the chipset drivers for the new mainboard... http://www.geocities.com/kilian00720...p/sysprep.html

and a power surge will normally take out the power supply.

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

Hi all, I have searched several tech forums for answers, found some, but none have fixed my issue.

When I start my computer, I get the black screen with one line across the top saying, "error loading operating system".

I thought by putting the Windows disk in, I could run a recovery. The only option it will allow me to select is to reformat the harddrive. I would like to figure out why I get this message and how to fix it.

If it can't be fixed...I have also tried to make this harddrive a slave to another one. I am able to see the new drive in my computer, but if you click on that drive, it says drive is not formatted. Is there any way I can get the data off of this disk?

everytime it load it keep saying "Error loading operating system" on the start up screen instead of showing the Window Xp logo.
why is it saying that?
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.

Hello and Welcome to TSF,

Enter bios: press F2 when pc first turns on
Boot order:
cd/drive rom
other devices (varies)

First lets test the harddrive.

Go here for a HD utility:
use seagate tools if yours is not listed, otherwise you can use these below:

dban - http://www.dban.org/download
killdisk - http://www.killdisk.com/downloadfree.htm

Burn the image to a cd:

perform a harddrive test, if harddrive test passes then
perform a full erase of harddrive.

if everything goes smoothly, proceed onto installing xp windows

After windows is installed, install drivers next.

Go here for the drivers for the pc:

Note: install the chipset first before any other drivers, reboot pc after each
driver install.

install protection - antivirus and antispyware protection for the pc.
Update windows using the window update icon under start button, all programs

After formatting the hard drive and reflashing the bios it started to say error loading operating system. I have tried fixboot and fixmbr. Formatted the hard drive with a quick, full, and low level. Ran the Maxtor Powermax utility that says my drive is fine. I have tried using another drive. Still all I get is error loading operating system.
I am about to try to totally wipe the MBR but that is the last thing I could think of unless it is a motherboard hardware problem. It has been working now for months without any problems. Also going to try Windows 2000 to see if that makes a difference.

Hello experts,

My IBM PC (Model R51) gets "Error Loading operating system" message at start up.
Advice that I have been given is to go into the IBM recovery Program and take the option for a Full Recovery (e.g. Reformat Hard Disk and re-install Windows XP, etc.).

I assume that this will overwrite everything on my disk (why didn't I invest in a backup device!!!).

Is there any other options for getting round this problem and saving data?

My computer recently decided to stop booting normaly and to load a black screen with "error loading operating system". The computer was running fine beforehand but I have a hunch it is something to do with my Motherboard rather then my windows installation.

My computer specs are as follows;
Operating System- Windows Vista 32bit
Motherboard- Asus M4A77TD Pro
Processor- AMD Phenom II x4 840 @3.2Ghz
Ram- 4 Gb
Hard drive- SATA SS Samsung HD103SJ

Now i have tried to boot from a copy of vista CD to use the command prompt to fix the MBR but it will no longer boot from the cd. It would at first but because my computer clearly dosent want me to fix it, it has decided to stop booting from the CD.

Now when i say it wont boot: it will boot into the loading screen where it says it is loading the files on the cd with the loading bar. Once that completes it goes to the microsoft loading screen as if it was starting up and then instead of going to the installation/recovery page it just loads a black screen and stays there. Nothing else will happen.

I have absolutly no idea how to get around this so im wondering whether my hard drive has really just died completly or whether my Motherboard is extremly corrupt. And yes the boot priority is set to boot from CD 1st.

Your help is really really appreciated!

A:Error loading operating system.

Why do you suspect your motherboard? Often it's the owner's "hunch" that solves these sorts of problems, so it's important to know why.

Meanwhile, let's start with these free, bootable diagnostics: Initial Hardware Diagnostics
If you still can't boot from the disk, then try removing both cables from the hard drive and seeing if you can then run the memory diagnostic (this sometimes happens when a hard drive is dead/dying).

OOOOOOOOK, this has been my own personal Headache for a couple days now and i'm really running out of options. I'm trying as hard as i can not to resort to reloading a system, so i come here for possible assistance.
Start from the begining, get a Gateway GT5622 that was apparently viral with a corrupt operating system. Unfortunately those weren't the only issues with this system, the hard drive has actually failed in front of my eyes. Now, i have attempted a windows in-place upgrade repair, XP PRO SP3 install disc. it had no problems in the start of it. rebooted after files were copied to continue setup, got a kdcom.dll is missing or corrupt, so i copy from another XP Pro machine the kdcom.dll to a flash drive, now when trying to boot to a mini xp, via hirens, it continuously locks up on me. so i pull the drive and attempt to move the file externally, this is when i realize the original drive is bad. so i image over what i have on old drive to new drive, i was surprised to see it actually work considering how much ticking and clicking original drive was doing. So i attempt to boot with newly imaged drive and get a blinky cursor on a black screen. so i boot to recovery console /fixboot /fixmbr, ran a plethora of chkdsks until they came back with no errors detected, and have even attempted the inplace upgrade repair again... and of course none of these have remedied the situation. anyone have any suggestions, ideas, SOLUTIONS?!?!  please post back. i check my forums...

A:Error loading operating system

The only logical answer/solution for a system with such problems...is a clean install, IMO.  The system dates from 2007, so it's probably still capable of adequate performance, assuming there is no evidence of a motherboard problem.
If the owner user created recovery disks...as specified in the manual for this system...then I would employ those.

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.

I had been using my computer and I got a blue screen. I didn't think much of it, but when I tried to restart, the BIOS stopped with a message "Error loading operating system" and understandably won't go past that. I have a multiboot linux live usb with puppy and ubuntu so I can access my computer but in puppy my hard drive isn't showing up (haven't checked in ubuntu yet). What can I do to repair my OS/hard drive?

A:Error loading Operating System

Well...IMO...if the hard drive can't be seen in linux...that would be an indicator of a possibly failing hard drive, with just a matter of time before all goes awry.
First thing I'd do is move anything off that drive...to a safer location.
Then, I would run a hard drive diagnostic on the drive, with the expectation of bad news.

I recently bought a new hard drive, and decided to upgrade from Win98 to Win2k. I put the new hard drive in the computer, and started to install Win2k. The setup program ran, then rebooted the system, and I got the 'Error Loading Operating System' error. Nothing I did seemed to fix it. I repartitioned, I tried NTFS and FAT32 partitions, that didn't help. I tried fix mbr and fix boot from the recovery console, nothing. I was able to install Win98 without a problem, and decided to upgrade from that, but I still got the error.

I finally found a message somewhere that gave me an idea. The new HD was a Maxtor, so I went to Maxtor and got their PowerMax drive checkout software. I did a low-level format of the drive, and then Win2k installed without a hitch.

I'm not exactly sure WHY I had to do a low level format, as this was a brand new drive that had never had anything on it. But, the point is, it worked.

So, if anyone is having problems with installing and getting the 'Error Loading Operating System' message, try doing a low level format of the hard drive and see if that helps.

I had seen a few messages about this error on this message board while I was looking for a fix, so I thought I would post my story and how I fixed it, so that someone else may have an easier time than I did.

Last night I was playing an online game... It froze on me so I decided I would take out the battery (so I could turn it off... Stupid, yeah? I know...). When I turn it on now, it has the message: Error loading operating system. I'm not sure what to do about it... If anyone has any idea on how this even got here in the first place, please do tell. Umm... Not much more to say, except for the fact, if you guys don't mind, please put things into simple terms. :D

I come home from work, open the lid on my comp, and see this black screen. I've never messed with the HD, or have had any problems like this in the past. When I left the computer everything was fine (I left the power on) After seeing this message I hit the power button and tried to reboot again, only to have the same issue. What the heck happened? Anything I can do? I have windows 7.

Hi -

Boot with your Windows 7 DVD or via the HDD recovery partition and try system repair or Windows System Restore.

Hi there. I've searched the web and these forums for information about this error message, and found quite a few suggested solutions; however, this error seems mostly to occur after a fresh install of Windows. This is not the case for me.

Over the past month, I have noticed my computer running slower, and crashing more often. It became particularly severe during the past week. I would get programs simply freezing on screen for a minute before I could move the cursor again, or simply freezing so long the only option was to restart the computer.

Two days ago, I woke up to this black screen with the message "Error Loading Operating System". The only change I have made to the system recently is, two weeks ago I got a blue screen crash and after reporting the issue was taken to a website which said the crash was due to a chipset driver of some kind and that I should update it, which I did as per the instructions that were given. However I had the slowdown and crashing prior to this so I'm am not sure if it is related in any way.

Any information or suggestions anyone could give is very much appreciated, and I thank you for taking your time to read this post.

I have a Dell computer with Windows Vista 32 bit. The computer is only about a year and half old, and works great, that is until now.

The tower sits on the floor under the desk, and one day my dog went under the desk and knocked it too its side. I stood it back up, and suddenly the computer screen froze with a beep. I restarted the computer, since I couldn't do anything, and the first restart was successful. It went to the login screen, but it was kind of messing up so I decided to restart again but when I did, instead of it loading all the way like before, the screen went black and it said "Error Loading Operating System" after the Dell logo came up. I don't know a lot about computers so I asked a friend, and they told me maybe something disconnected from the motherboard when my dog knocked it over.

I opened up the computer and everything was connected, but a little dusty, so I cleaned it out, connected the computer again, and same Error comes up. So I was hoping if you guys could help me out. Since I'm 'dumb' with computers, could you guys give me step to step things so I can fix this problem. Thanks for the help! I hope I gave enough information to get this whole thing sorted out.

sounds like the hard drive was damaged in the fall. thats what it sounds like to me anyway, you may need a new one. if its still under warranty Id contact customer support and say its broke, otherwise you will most likely have to replace it.

I have a problem with my laptop. it's a ideapad z470.
my problem is that whenever I turn on the laptop, it gives me a error loading operating system message.
I have searches multiple threads and tried them but it didn't work for me.

What I Have Tried
1. windows repair disc- after it loads the Microsoft loading bar, the screen stays black
2. windows installation disc- screen turns black but with movable cursor.
3. pressing f8- after loading all the files, it just stays there for a few minutes and then black screen with cursor.
4. re-putting back in the harddrive- no effect
5. system recovery button- stays on "loading files" bar for a while then to black screen

The BIOS detects the harddrive though.

I recently got the message "error loading operating system". My computer was working fine, so I have no idea what is causing it. I left my comp in standby mode and when I went back to it several hours later it was completely turned off (which leads me to believe one of my roommates turned it off by pressing the power button on the comp itself). When I turned it back on it gave me the error message, but when I hit F12 during start up and select "primary master" startup it wil work perfectly. Whenever I try to restart it keeps giving me the error. Does anyone know why my comp will only work under these conditions. Any help will be appreciated.

A:error loading operating system.....again

Check you BIOS setting and make sure your machine is set to boot from the C: drive. Also you might want to run a scan disk. Goto My Computer > Right click on C: drive > left click properties > click tools > then under error-checking click check now > check both the boxes at the top. Next time your computer reboots it will check the intergirty of the c drive. Let us know what you find.

Hi there,
I own a DELL Dimension 4600C, and I had a trouble with it last week. I got the message for "Unmountable Boot". I misplaced my original Windows XP Pro CD, so I used my friend's bootable XP CD, and try to check disk. I followed instructions on the Microsoft website, nothing worked until I made bootable floppies and tried to repair the system. It wouldn't complete the repairing and always went back to the blue screen with the unmountable boot error.

I decided to reformat, so I deleted the partition and tried to install the new windows. It took way too long to delete the partition, and at the end I received a message indicating can't be completed ( I can't recall the reason).After that, I keep getting black screen with error of loading operating system.

Any guidence or help to resolve this problem will be really appreicated.

Welcome to TSF,

Download and run the drive manufacturer’s utilities If the drive passes diagnostics, use the utility to wipe or zero the drive and try the install again. Sounds like remnants of the old install are preventing the new install

WHAT error message?

This morning, I went to turn on my PC and received a black screen with the following message - Error loading operating system. I have Windows XP Professional.

Yesterday, I was having trouble w/IE 6.0 - it kept radomly closing on me - so I thought perhaps I had a virus. I installed the latest MS updates and then ran my virus scan, Etrust antivirus overnight. When I checked out the PC this morning it had rebooted and was showing a black screen w/the above-referenced error message.

I do not have an Automated System Recovery disk for this PC, and, even worse, I do not have my files, etc., backed up (yes, I'm an idiot). Otherwise I probably would have simply reinstalled Windows

I ran a diagnostic called BootMaster Partition Recovery (http://bootmaster.filerecovery.biz/index.html) and it told me that an NTFS volume on drive 1 appears to be in an unstable condition (called it a dirty volume) and BootMaster couldn't repair it, and that I should call Microsoft, which I'm not really inclined to do (I'm happy to pay for tech support, but I'm not convinced calling Microsoft is the most expeditious way to go).

So, any thoughts out there on whether or not there is any chance I can save my data?

Many, many thanks.
