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.)

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?

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

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

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.

I have recently encountered an error when booting up my computer that says "error loading operating system". I tried a format, I tried reinstalling windows xp....I did a fixboot in Repair console and chkdsk...still nothing. Tried switching my BIOS to read the drive in LBA mode....The message didnt come up..instead a black screen with color characters on the screen showed up..and nothing happened...

I have no idea what is causing this error....

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 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.

You could connect it to another PC as a slave drive, get all your important data from it and then reformat it and reinstall your OS.
Before you reinstall the OS, download to disc the Disc Utility for your particular Hard Drive, ie; Maxtor/Seagate, WD and run a
disc check to make sure your drive is still in good shape and if shows the disc is good, use the same utility to ZERO out the drive,
then format and reinstall

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.
Ask me if you want any more information.

Thanks now its solved

!!!!!THANK GOD!!!!! I just had this same problem and was reading this forum to try and find an answer (though sadly i did not). Instead i decided to boot from my original windows install disk and run the recovery console (press R). at this screen type 'FIXBOOT', it will prompt you for a confirmation so just say yes (type 'y'). It will write over your previous boot files BUT NOT YOUR PERSONAL DATA!!!!! after this runs and says that it has completed successfully, type 'exit' and the console should quit and your computer is back.edit: caution, i think this is only a temporary fix (meaning you'll have to go through the same procedure every time you boot your computer) so i would recommend backing up all of your files onto an external hd and then reformatting your computer (by the way i have the same computer, Dell Inspiron 5100, so this fix will probably work the same for you as well).Was having the same problem. Followed the instructions, but computer still won't boot. Now, its not even giving me the option to boot from CD. The new message Reads "Windows XP could not start because the following file is missing or corrupt:\WINDOWS\SYSTEM32\CONFIG\SYSTEM" At this point, I just want to do a clean reinstall of XP. There is no data of importance on the computer. Any help would be greatly appreciated.

I'm looking for solution for my friend's laptop using WinXP SP2. She keeps getting the "error loading operating system" when WinXP starts.

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 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

A:Error Loading Operating System

Hi megatron, and "Welcome to the Seven Forums." . . .

Now to the problem at hand. First we need to know what operating system you are using. Microsoft Office 2007 is not an operating system. To find out what OS you are using "press and hold the down the Windows Key then push the Pause Key." Doing this will bring up what is known at the "View basic information about your computer."

From that screen you will see the basic information about your operating system and the computer itself. Now type in that information so that we who wish to help can see what operating system, and computer you are using. With this information we can at least start to give you some ideas as to the problem. . .

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.


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 am using windows 7 on my computer and recently I figured that my computer started freezing a lot so I decided to install a fresh copy of windows. I did the same and scanned my whole computer and found no viruses either, the freezing problem was still not fixed. I searched up some but found no good solution. Then somehow the condition started getting worse, my computer stopped booting and it started restarting itself at the win7 startup animation. And then even worse.. now it only shows a black screen after turning it on and then shows the error "error loading operating system"after a few minutes. I tried many things I found online but nothing worked since I can't even get Into my windows for now. Safe mode isn't working either, I have no idea what to do now, please help me with this error. Or could it be a hardware problem too?
Please remember I only have a bootable windows 7 USB with me, no cd/dvd at this moment if the fix requires a copy of windows.

I did try to use the F8 key after BIOS (Dell Inspiron 530 Bios 1.0.13) but no avail just clicked - i am able to get to xPUD via the boot disk but not sure where to go from there - if you need a copy of the mbr this can be provided. Any help is appreciated would really like to fix this. It is our hub for our family network and obviously is a drag. The wireless is still kicking and all can still use the network so no issue there.

the first error that started all this was an invalid disk partition or something like that - that is what lead me down this road and eventually to you!

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.

Hi, I was programming on my computer and a few days ago, my computer shut off on me randomly. I don't know how and today, I restarted my PC and come to find out that I receive an error saying, "Error loading Operating System.". I'm not sure why it can't detect my OS. I've looked it up on what caused it and how to solve this issue, but no solution has come to me yet. They say I have to update my BIOS, but I came here to make sure if this was true or not. If this is, how would I update it since I cannot go into safe mode nor regular. I can't re-install Windows XP; I just get an error. The error is written in binary, "0x00000000". It says that three times. I'm not that good with binary and I was wondering if anyone knew about what it meant. I was also wondering that if I did need to update my BIOS, and if I were to do it with a USB drive, how would I format the USB in order to boot from it? Help is very much appreciated. Thanks.

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:


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.

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...

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.

I have a Dell Inspiron 2600. I turned it on and got only a blue screen. someone looked at it to see if they could fix it and they were unable to do so. they have given it back and now i just get a black screen that says Error loading operating system. I cant even get into the set up menu or anything. Is there any way to fix my computer?

A:Error loading operating system

Can you boot into Safe Mode. Press F8 immediately after you start the computer begin pressing F8. This will take you to a page that looks very similar to the picture below. This is the Advance Boot Options. You need to use the up and down arrow keys to navigate on this page. Once you have moved the cursor to the option you want press Enter on your keyborad.

You have or have access to a retail XP installation CD that is the same version as the one installed on this Dell, eg. Home or Pro?

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.

Hi everyone. I really don't have a clue about what has happened to my pc. I shut it down fine last night - no problems. I haven't installed anything new either. This morning i turn it on again only to see a black screen with: ERROR LOADING OPERATING SYSTEM.

I tried putting the pc into safe mode but no luck. I tried F1-12, DEL,ESC etc on boot up but it just refuses to go into safe mode. The error message remains and doesn't budge. All i hear is a beeping everytime i'm pressing one of the buttons mentioned above. I honestly don't have a clue where to start with this. I'm really worried about losing my files as i only have half of them backed up and they are really important. Is there any way i can fix this problem and retain my files at the same time? Any help would be appreciated. Thank you

EDIT: here is a pic i took of the problem:

The line just out of sight in the screen shot would be the Pri. Master drive. Is there a drive listed there? It looks like it's trying to boot from CD, possibly because there is no hard drive found. There is a distinct possibility that your hard drive has gone south.

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.

I have been unable to load Windows XP on the new hardrive (only drive in the system). Initially, everything apperared to be working. The expected screens appeared during setup and got down to formatting the hardrive. Because this process is lengthy, I left the computer and on returnng the computer had shut down. Any attempt to restart the process of loading Windows XP gives the above error message. Disconnecting the hardrive allows the seup process to continue until setup is unable to detect a hardrive, then it stops. How do I get around this error, which I suspect has something to do with the hardrive? Any help is appreciated!

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?

A:Error loading operating system

If your xp installation went through smoothly without skipping any of its files then i'd suggest you to download EasyBCD. This one will allow you to modify your mbr at ease, it works fine in vista but in xp it requires dot net framework 2.

I am trying to load Windows XP on a 500 G hard drive that I have just formatted. I checked the Bios and changed it to boot from the CD ROM, and when I turn it on, it goes through the initial start up checks and then I get this error message, Error Loading Operating System. Any one have any ideas.

Thanks in advance

A:Error Loading Operating System

Could be something to do with the BIOS, check for BIOS updates. Also, make sure that you are deleting the partition and creating a new one, then formatting. One other thing, make sure that you don't need to install a driver for the hard drive during Windows setup if all else fails.

I have this same problem. I set partitions for installing XP the setup copies the files, restarts and says error loading operating system.

I have tried:
Taking out 1 of 2 RAM sticks
Updating BIOS
Swapping CD ROM drives for install
Used a different XP installation disc

The BIOS detects both HD and CD-R
There is only 1 IDE port on the MOBO so its running the CD ROM and Hard Drive through one cable, its awkwardly wired but iv done this before and it works so im presuming this isnt the problem. Jumpers are set correctly for master and slave. The ribbon cable end is going to the Hard Drive MASTER and the middle end of the ribbon cable is going to the SLAVE CD ROM.

The PSU is 400W running an Athalon X2 4200+, 2 gigs of ram, 160gb hd, 1 dvd rw, an ATI x700
Dont spose this is related in any way.

No idea what else to try, has anyone got any suggestions?

A:Another Error Loading Operating System

Using a generic xp disk

1. make sure the ide hard drive is set for the 2nd boot device in bios/turn off sata

2. delete the primary partition, recreate it and slow format from the cd, this will set that partition active

3. if that doesn't work? what is the motherboard brand and model number
reusing an old pata drive in a newer computer?

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.

Hello I have a Sony VAIO VGN-A250 notebook running Win/XP Home. When I boot it up it goes to "Error loading operating system" I know the HD is detected because I checked the BIOS and it lists it as the 1 boot device.

If I use the recovery disks will I lose all the data on the HD? Will I have to reinstall Windows?

I don't have the recovery disks that came with the notebook but have the Win/XP disk for my Dell desktop, can I use that disk?

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.
