Dual boot Windows XP and Ubuntu: XP won't boot.

[Dotan Cohen]

I have installed Ubuntu on a neighbour's computer in a dual-boot
configuration with Windows XP, which was already installed on that
system. Windows is on sda1 and Ubuntu is on sdb1, with Grub on sdb and
the BIOS configured to boot from sdb. Before the install, BIOS was
configured to boot from sda, which was the existing Windows install.

Upon startup, the computer gets to the Grub screen just fine, and if
the user selects Ubuntu then the computer boots as expected. However,
if the user selects Windows then he gets a black screen with the text
"Starting up...". This screen does not change, I have waited over an
hour to see if it would continue. However, if I change the BIOS
setting to boot from sda then Windows boots up fine. I tried changing
the Grub boot configuration for windows from (0,0) to every other
logical value, but Windows would not get past that "Starting up..."
screen.

Any ideas on what to fix? Thanks in advance.
