Re: Installing Windows XP on Vista (not dual booting)
use the xp cd to do a format then. if you have lots of data on there you could make a new partition, store only what you want to keep on this, then format the old partition with vista on it and install xp on there. then you can merge them together which would save you backing up the files externally.
