grub2 on sata HD detects xp on ide hd but will not start

I have 2 hard drives:
1) SATA HD with Ubuntu 9.10 (installed when drive 2 was not installed (plugged)).
2) IDE HD with Windows XP (installed when drive 1 was not installed (plugged in))

Each OS works fine when the other drive is not plugged in, and when both drives are connected to the motherboard, the grub menu displays the XP Option, but does not start it.
Ubuntu starts without problem.

To start XP, I have had to unplug the SATA HD with Ubuntu 9.10

Please see the attached file for detail info.

Any ideas on how to solve the problem?

I am attaching further info here:
