Might be a corrupted system file in Windows. You can try doing a repair installation if you have your Windows XP installation disk, which will use the system restore feature to bring you back to a prior point where everything worked. Instructions are here.

Other than that, if the system actually doesn't recognize the hard disk the disk might have a problem. When the computer boots up, does the BIOS detect the disk?

When you first turn the computer on, before it tries to go into windows, you can usually enter the BIOS by hitting the delete key (sometimes another key - see what the startup screen says).

Don't change any of the settings. But if you can get to the screen in BIOS that lists your hardrives you can see if your hard disk is listed. If not there might be a problem with the disk or one of the cables connected to the disk. Usually just hit the escape key to get out of BIOS with no changes.

That message means that the harddrive may be failing, or is just may need a simple chkdsk.

Boot up with your Windows XP CD.
When you see the menu, choose RECOVERY CONSOLE.
You will see a command prompt. If you did NOT set a password, just leave it blank and continue.
When you finally reach the RECOVERY CONSOLE and you just see a prompt blinking, type the following code in and press ENTER:

chkdsk /f /r

Let the scan run. This will take awhile. After it is done, take out the Windows XP CD and reboot the computer. Can you access Windows now?

A repair installation from the XP disk won't reinstall windows, it will just take it back to a prior point in time where everything worked (e.g. maybe a week or two ago). You won't loose most of what's there, just any changes that were made since that last restore point. The process will typically not affect any documents on your hard drive.

All a repair does, is fix the OS by rewriting all the corrupted SYSTEM files, and you will also lose most MICROSOFT UPDATES. You will need to retrieve these again when you repair the OS.

Try running the chkdsk though for me please :whistling:

Yeah that seems about correct.

Is your PC a manufacturer PC? Does the CD have a hollowgram color?
