I'm trying to dualboot Vista and Kubuntu on my Dell XPS M1330 laptop, and I'm having problems.

First off, I tried installing Vista first and then installing Kubuntu, which seemed to work fine, but when I tried to boot Vista, I got a BSOD and my laptop rebooted.

I then reinstalled my Vista thinking something had gone wrong while installing updates for it, and it worked. But now grub was gone, and after reinstalling that, I'm back at the BSOD -> reboot problem...

Any suggestions on how to fix this?
