I managed to get Vista up and running again though.
Apparently when XP sets up a partition on the HD it leaves 8MB of unused space, and Vista did not like this.
I deleted the NTFS partition altogether and rebooted, and the system recovery part of the hard drive took over on restart and reinstalled everything.

So I still lost all my installed programs and almost a week's worth of video encoding just because I wanted to uninstall norton, but at least I'm up and running again.
