Re: Vista Restart
I hope you have installed Ubuntu "behind" windows and you didn't move the windows partition to the end of the disk. If you did, you probably need to reinstall windows, although a vista guru might know how to fix it.
I'm trying to say that if windows was installed on partition 1, it should be on partition 1 after the upgrade as well. If it was on partition 3, it should be on 3 after the upgrade.... etc.
If Windows is still on the first partition you should be able to boot it with the following lines in your /boot/menu.lst (Windows is on the third partition of the first drive (sda) in this case):
title Windows Vista/Longhorn (loader)
