Anyway I second what has already been said: being ext4 the default file system used in Ubuntu 10.10, the partition(s) on which Ubuntu was installed (generally more than one as it's common usage creating a partition for / and a partition for /home, plus the swap) have to be completely deleted before you attempt running the Windows 7 installer. Make sure you have backed up all your data before you proceed wiping them.
Other than that, I don't see anything different than a clean install in this case
