windows xp repair cannot detect existing installation

Hi I am trying to repair a Win XP install that was orignially upgraded from Win 2000 so Windows is sitting in the WINNT folder. The drama is that when I try to use the disc to run a repait install it does not give me the option to repair but only to install from scratch. Tried 2000 and XP CD and tried chkdsk /r , fixboot and fixmbr.

Actually this is the original error:

Windows NT could not start because the below file is missing or corrupt:


I tried copying the file from a backup with no luck.
Try using system restore from Ubcd4win to go back before the corruption appeared.

If restored successfully, try a repair afterwards or an in-place repair.

Get backup of any important data firstly!

How have you tried CompTroub,
is this xpsp2?
Do you have the COA?
Slaved the hard drive and tested it is functioning ok?
I use the 3 R's, Rebuild Repair and Recovery
for repair
to perform a reinstallation of Windows XP, sometimes called a repair installation?
You will need the COA key on the sticker and the xp setup disc that is installed on the computer
Configure your computer Bios to start from the CD-ROM drive  insert your Windows XP Setup CD press f10 to save and exit, and restart your computer.

When the Press any key to boot from CD message is displayed on your screen, press a key to start your computer from the Windows XP CD.
 Press ENTER when you see the message To setup Windows XP now, and then press ENTER displayed on the Welcome to Setup screen.
 " Do not " choose the option to press R to use the Recovery Console.
 In the Windows XP Licensing Agreement, press F8 to agree to the license agreement.
Make sure that your current installation of Windows XP is selected in the box, and then press R to repair Windows XP.
Follow the instructions on the screen to complete Setup.

Here is some good guides I have kept  illustrating the steps,, please look below the typing.

Another method is to create a new folder to install xp to. Name it WINDOWS2
same principal as above but use the run setup and install windows instead and when your current installation of Windows XP is highlighted it will ask you if you wish to install over XP you say no and it will install to a new folder in c drive called WINDOWS2 this has worked for me and then I boot into that and fix the old windows by checking the boot-ini
You only need 250 megs to do this.
Do you have have the 1386 folder in C drive?
At any time before you actually start setup you have the option to QUIT
Method 3
hal.dll file missing
Boot from a Windows XP CD.
 At the next screen press R to repair using the Recovery Console.
Press the number correlated with the Windows installation you want to fix. Typically this will be #1.
In the Administrator password press [ENTER] if you have not set a password for it.
expand x:\i386\hal.dl_ y:\windows\system32\hall.dll
where x is the letter of your CD-ROM and y the letter of the drive your operating system is installed on.
Take out the Windows XP CD and type exit
If none of the above fix it then I dont think you have any option but to check if this system is ready for xpsp2
Coming from windows 200 shoudl be performed on a new clean partition, have the sata drivers ready if you have a sata hard drive.
You need to press F6 to install them  if i remember :)
good luck

You probably do not use the same version of XP as used for installation / upgrade, as you said (pirated version, perhaps ?!). Don't you think it's time to do a fresh install ? (Upgrade to XP from 2000 ... bleah ... :D ). A Happy New Year to you and your love ones!
