Help installing Dual Booted System Drivers (Win Vista - XP)

What exactly does it do when it fails? Does it not go through completely, stop during the middle? Etc./

Also, there may be a problem trying to make an XP partition over a Vista partition. Now, I know there was no sort of conflict before Vista with preexisting OS's, but Vista is very notorious of taking over everything after it's installed, that could be a possible problem? (it's so conflicting in muh head).

I'll try tomrrow at work when I'm not so tired and find you the correct drivers for your laptop..
