I am currently dual booting on two separate hard drives. XP professional 32bit on one and Windows 7 professional 64 bit on the other. No problems with this. I am going to buy a new mother board but swap my processor and ram from the old mother board to the new mother board. The new mother board is the same make as the old one but much more advanced. My old mother board is a Gigabyte GA-H61M-S2P-B3 (Rev 1.0.) The new mother board will be a Gigabyte GA-Z77X-UP7 (Rev 1.0) Will this change in mother board affect my dual booting and if so do I need to do anything in advance. Both disks are backed up at regular intervals.
