At least the BIOS's I have used map the drive that you boot from as the first hard drive. This was needed by older versions of Windows that had to boot from the first hard drive. This gets tricky because you do not get this change of mapping when you boot from the CD/DVD drive. So the map created when installing/upgrading from a CD/DVD is not the same as when you tell the BIOS to boot from the IDE drive instead of the SATA drive. Now, if you are using the Windows XP boot loader to load Grub, then you will probably need to update the boot file you created from the boot record on the IDE drive to reflect the upgraded version of Grub. This is because the file locations on the drive for stage 2 (or stage 1.5) are hard coded into stage 1, and it is stage 1 that you copy to Windows. Chances are, the file locations changed in the upgrade. But part of the old files may still be there.
