restoring mbr

[Paul Maser <paul@maser.net>]

I have two hard disks that I used for linux and now I'm trying to
use them with Windows, but with both drives the computer (Dell)
cannot see the hard drive as bootable. It comes up with the error
message "Primary hard disk drive cannot be found."

The BIOS recognizes the hard drive and I can install Windows or
linux, but it won't boot until I hit F1-ignore.

I had this problem before and rewriting the MBR fixed it, but this
time I have tried to rewrite the MBR using a DOS 5 boot disk, the
Win2K fixmbr and fixboot utility and even loaded debian "woody"
and tried a lilo -U, but nothing has worked.

Anyone got any ideas.
