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?

Thx

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

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.

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)

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.

Hello Saketis, welcome to the forum

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?

If you have a boot disk with fdisk on it boot from it. At command prompt type fdisk /MBR

So I was attempting to fix my laptop hard drive, so I connected it to my computer using an external enclosure. My laptop was having problems finishing a Windows XP installation, so I decided to try to install XP using my other computer. I booted my Windows Vista based computer to the Windows XP installation cd. I selected the laptop hard drive to install Windows XP on to. Once it finished formatting the partition, I received an error stating that the hard drive was unable to complete the partition process. I just assumed that the hard drive was dead. Therefore, I unplugged the laptop hard drive from my PC, and attempted to boot to Vista, the only OS on my PC. This is when I got the "Error loading operating system" error. I tried researching this problem, and I found this article:

http://support.microsoft.com/kb/919529/en-us

I was following the steps using the command prompt on the Windows Vista installation cd, in the repair section. Once I tried to enter "C:\boot\Bootsect.exe /NT60 All" which is the first step in the directions, it said that "C:\boot\Bootsect.exe was not recognized as an internal or external command"

I really think this is the path I need to follow, as I believe that Windows XP may have messed with the Windows Vista Boot Manager. If anyone has any ideas, please post. Thanks.

A:Error Loading Operating System

It looks like you may have deleted your boot information for Vista. You may have selected the secondary hard drive to install XP to, but it will still try to write info to your primary hard drive.

I'm not sure of a quick fix, unless you can do some type of re-install of Vista, but choose to keep your current system and just re-install windows vista.

After thinking about it, I decided to boot up off my Windows OEM CD. At the menu I chose "R" to go into the Recovery Console.

There is a problem with my old PC (Windows 7 x32, Intel duo core processor, 2.5 GB RAM) which was custom or assembled, it says 'Error loading operating system' and I have been trying to fix it for hours..
Earlier when this happened (A lot of times), I fixed it from the Repair option when I press F8 contineously, but when i keep on pressing it, nothing happens (System Repair Blackscreen does not come).
It happened when I pressed the restart button in my CPU when my PC was stuck for a long time, instead of waiting and manually restarting.
The biggest problem is that I LOST my Windows 7 CD. All I have now is just a USB with backup files.
When I put on the USB while booting, it says 'BOOTMGR is missing, Press Ctrl+Alt+Del to restart' but it shows the same thing when I restart.
When I pressed F10, It showed the Boot Option Menu, it had 3 options:
• SATA: Optiarc DVD RW AD-72203
• Realtek Boot Agent
• MBIC SS MMoser Baee Disk PMAP (That one is my USB)
These 3 didn't work either....
So, Please help me to find a way to fix it.

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.

Hello!

I know you all are quite good at helping others fix their problems, and I have been stalking these forums for quite some time. However, I have recently gotten an issue with my computer booting that I can not fix, or find a fix on here.

So, about two hours ago (On this current PC I am typing on now.), my computer decided it would basically freak out. I got a few three pop ups, saying sticky notes has crashed, gave me the option to select cancel. I got one pop up for each sticky note that I had up at that time.

Then curse had done the same thing, which I found was odd, as curse has NEVER once crashed on me.

Then suddenly, the dreaded BSOD appeared, and before I could even try to restart my computer, it shut it self off.

I went to start up my computer, thinking maybe it had just crashed. It did its normal start up stuff, got to the welcome screen, and took about 5 minutes to load past that. Once it did, another 5 minute load or so on a blank, black screen. I walked away as it was taking a while. I came back, and on the top of the screen, it said "Error Loading operating system."

I had no errors, or any other warnings before the system crash, nor did I have any viruses (Checked three days ago.)

My operating system is Windows 7, I use an Intel R Graphics card, and my computer is a HP touchsmart 520 PC, all in one, antivirus is the AVG free edition, and I use MalwareBytes, both are run on a regular basis.

Reboot into BIOS setup to see if the HD is detected. If so start with the HD tests and then work through the other Troubleshooting Steps for Windows 7.

You'll note we recommend an AV which is not AVG, which hasn't been recommended anywhere for years since it bloated up and never slimmed back down. We only see problems with it here. I'd uninstall it and install MSE asap.

So the HD and AVG look like your likeliest suspects, however if you still have the HP factory preinstalled Win7 then that is the worst install of Win7 one can have, so it could be a combination of these or something altogether different which will likely turn up as you work through the steps.

Now would be a good time to consider getting that one great Clean Reinstall - Factory OEM Windows 7 since you only need to get it right once, then save a backup image in case you ever need to reinstall again it would be a 20 minute reimaging operation.

I recently made my 2 partition laptop back to one partition and on reboot I get the error message 'error loading operating system' how do I fix this?

A:Error loading operating system

What steps/how did you, make two partitions "back into one"?

It sounds like you wiped the hard disk.

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 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.

Ok. Not very happy right now.

When I boot up my pc, it immeadiatly (or almost) jumps to black screen stating "Error loading operating system" nothing more, nothing less. Right before I got this message, I had BSOD "Driver IRQL not less or equal". The only changes to my system were opening my external hard drive to clean it. I am looking for a remedy to make this drive, os and all, useable again. Please dont repost saying reformat. That wont be of much help. Thanks in advance.

This problem basically came out of nowhere...comp was fine then bam..doesnt work. If you can help me I would greatly appreciate it

Thanks in advance.

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.

I think it's Windows 64 but it could be 34 I have no idea, and as I cannot get into the computer I am not sure how I would find out.can someone please help. I think I may need some recovery discs.

Hi
My computer been acting weird since about 4 days ago
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,
 
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.

Thanks,
Ballmoss

Hi

I'd be grateful for anyone's thoughts on this one.

I downloaded the latest security patch from MS [the one about remote takeover of computers] installed it, restarted and then got a horrible error message - error loading operating system. Its like an old fashioned command prompt that you see in the movies - just that single line on a completely blank screen with a flashing cursor awaiting instruction.

I'm running a dell 8200, with windows XP home, service pack 2 and all other patches etc. installed. Everything was fine prior to this. What happens is that I switch on, the graphics card details flash on the screen [as normal] followed by the Dell splash screen with F2 and F12 prompts and bios version [a08] then the above blank screen. Nothing works once the above screen is reached.

From reading the web I've kind of figured out that this is a problem on the bios and that, somehow, my bios has become corrupted. One solution offered on a few sites seems to be go into bios and then change the hard drive access mode from auto to large, but i'm not sure about this and it sounds a bit scary.

Any thoughts?

My prime concern is that I have a lot of data on my hard drive [stupidly only partly backed up - I know!!!] and I'm really worried about losing it.

I should confess that I'm a bit of a newie at these things and my technical knowledge is very limited so please, phrase any replies in simple terms.

Thanks.

A:Error Loading Operating System

My prime concern is that I have a lot of data on my hard drive [stupidly only partly backed up - I know!!!] and I'm really worried about losing it.Rightly so, but who among us have not been caught in this situation?Without addressing your original issue, I just want to speak to getting the data off of the hard drive. You could always remove the hard drive and install it in another computer as a 'slave' drive. The working computer should still boot up from the 'good' Master hard drive, and then you will be able to navigate (start > my computer) to the slave drive and recover your data. More info on how to install a second drive can be found HERE.But of course, if you need help with this or any other procedure you can just ask for help here and we can explain it in more detail or refer to somewhere on the web where it will be explained more fully.

I seem to have done the unthinkable and stupidly tryed to install a second Windows XP after having Windows Vista and Windows XP installed. As soon as my computer restarted after copying the XP setup files, I got confronted by "Error Loading Operating System". I've been searching around the net for about 2 hours now and it led me to a few different methods to try, which i did, but I still can't figure it out.

What I've done so far is put my Vista disc in and hit repair, then tryed the first option to fix the startup, which didn't work. I then went into the CMD option and tryed to fix my boot file. I understand this is done through bcdedit. First I executed "bootsect -NT60 All" and it reset the master boot to be handled by bootmgr but nothing changed except a new symptom appeared. When I restarted. instead of telling me to press a key if I wanted to launch into the DVD, it came up with something to the effect of "CDROM: BOOTMGR MISSING" (I can't remember exactly). Then after restarting it just asked normally if I would like to launch into the DVD, which I did again and this time I went to BCDEdit and deleted the original Windows XP boot details. Now I'm left with just the Windows Vista boot details but the same problem still arises.

When I view the details on Windows Boot Manager through BCDEdit it says that the device is on partition C: (the partition with XP) and the Windows Boot Loader details says that its device and osdevice is on E: (th... Read more

*Sorry I couldn't figure out how to edit the original post*

An update to what I've done, I just realised that bootmgr is infact in the right place and there really doesn't seem to be any problem. I also re-added Windows XP through BCDEdit but no change.

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?

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.
