I am not fully understanding the problem.

Is GRUB loaded on the XP drive, or is it loaded on the FedoraCore 1 drive?

Which drive is booted first by the BIOS ?

How are the drives set up; primary/master and primary/slave, or is one a secondary, and which are which?

When using separate drives for each OS ( which is easy ) I usually like to install Windows on the primary drive first, then change it to a slave or secondary drive and make the Linux drive the primary/master, then using GRUB to boot to either: If I want to remove the Linux OS for any reason I just pull the drive and make the Windows drive the master/slave again, thus eliminating any need to change anything as far as boot loaders. If I want to replace the Linux version/distro, I merely have to format the Linux drive, reload, then set up GRUB on the new distro to boot Windows ( the second drive. ) ( Or one could set the BIOS to boot to the Windows drive first if that is an option available, depending on the original setup.)

The only time I ever loaded GRUB ( or Lilo ) on the Windows drive was if I was installing more then one OS on a single drive. With the newer hardware, even that is made simpler as the Windows OS can sit on the first partition nicely by itself, and GRUB can be loaded on a second with the new OS; make the second partition active and not the first, and BANG!, you now have the GRUB boot loader at start-up, but can at any time go back and make the first ( Windows ) partition active and it boots directly into Windows.

So I think what I am saying is, to make this brief, could you supply details of your architecture and your grub.conf files so we might understand what you are facing? There are other alternatives out there ( like using win2k install disks ) to doing repairs besides the original install disks, but to offer a proper solution one needs to know what the problem is.



BTW, anyone else's browser hanging up on view.atdmt.com ??
