I have been trying to install Ubuntu on the new Vista machine for a while and MS makes it hard as they put some files at the end of the filesystem that you have to remove, but they are to do with some recovery features you have to turn off, it is much easier to simply install Ubuntu in the Windows partition these days, not as good performance, but there you have it, now it is in the NTFS file system and all the partition hassles go away. I just did it this way to try out.
