can't get kubuntu and windows xp to dual boot

[x1650]

i'm having trouble with getting windows xp and kubuntu to dual boot
im using 2 harddisks 1 with windows and 1 with kubuntu kubuntu booted fine then i told the bios to use my windows harddrive windows worked fine then later on when i switched back to the kubuntu hard drive through the bios it attempted to load linux as usual but it failed and wouldent load any farther. What could this be? also is their any drivers available for the radeon x1650 for kubuntu

thanks is advance

Have a look of Section A of the 2nd link of my signature on using two hard disks booting Windows and Linux.

You can use the boot loder Grub, which is used by Kubuntu, to do the bios switching.

Your first priority is to go back to the first step of booting up Kubuntu as the first bootable disk.
