When you boot from media/cd/dvd the drive letters got changed.

please consider D drive as C Drive.  As c drive is your boot media.

I've run into this same problem on multiple Windows boxes. Most of the time, the fixes mentioned above work. Some times they did not work for me and I either ran a Windows repair from the Windows CD or clean Windows install on that box based on what worked best and how long I'd been working on it.

Sometimes, it's quicker to call it quits, backup the data and run a clean install. It's better than continuing in a lost cause.

Hope This helps!

this XP has SP3 and I put the disk in a Windows as 2nd disk and I defraged the disk.

So I think this kb doesn't correspond with my issue but If you think it's posibble I do it.

Depending on how you installed XP, you might have to modify the Microsoft process. You need to evaluate that and make a decision. I can't tell how you installed Windows or what mods may need to be completed.

Boot using the Windows XP installation disk, press R. Then type the following commands:
note : you can test after each command

      BOOTCFG /rebuild

      copy E:\i386\NTLDR c:\
      ATTRIB -arsh ntldr
      copy e:\i386\NTDETECT.COM
      ATTRIB -arsh c:\

E: should be the location of your CDRom where you have the Windows install disk located.
and check if those files are in the root :   NTLDR   boot.ini

Contents of the boot.ini file :
[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect

check this too for more info :

ok nobus, I'll try but

If I do "copy E:\i386\NTLDR c:\"  I get an error "access not allowed".  If I try enter to a Directory in C: I get the same error " access not allowed"
