Before grub, during grub, post grub? Can you enter your BIOSto see if it sees your drive properly? One solution to try would be booting from a rescue CD and re-installing grub. If you simply want to get Windows back up initially you can run fdisk /mbr which will cause the master boot record to be re-written for Windows. So Windows should boot up fine again. If it does, then your issue is not likely your BIOS. Jacques B.
