Where did you install Grub ?
On the flash?
If it is on the Flash and I think it is, than you only can boot with the flash installed !!!!
You don't need to install grub at all with a flash, because mostly you can boot (option in the bios) directly!
You can make the XP drive bootable again from the system cd.
