Re: Upgrade dual boot machine

One other thing, since I haven't seen it covered, BACK UP EVERYTHING,
especially any contact information/bookmarks/etc... I've had enough XP
"upgrades" cause a loss of something I wanted, that it's become second
nature. Even if the backup takes a dozen CD's or DVD's, it's worth it to
be sure you won't loose some critical license or setting value you
cannot replace. If you have any DRM-protected media, make sure you
perform a license backup separately, since those licenses won't
transfer, and cannot be recovered any other way.
