Please forgive me for this stupid question, for some reason I haven't kept notes on how I done this and Google is not being my friend.
I have a PC with Windows XP installed and want to dual boot it with Windows 8 upgrade edition. I have 5 licences for XP, one of which I used as an upgrade to 8. The XP installation on my PC does not have the license that i used to upgrade to 8 so no problems there but for the life of me I can't remember how I done it last time.
I have had to replace my hard drive, I have cloned XP and 8 across but the MBR didn't make the copy (bigger drive) so I had to do an XP repair to bring it back. I'm happy to reinstall 8 as i don't use that much (yet) but I don't remember how to do the dual boot.
