I have a partition on my hard drive: C & D. My "C" Drive has good old Windows XP and "D" drive has Windows 7 release 264 pre-RTM (activated). I have not used XP for six months. I got the Win7 RC and kept upgrading all the way to release 264... compliments of ... WZor Question: I want to format my C: [XP] drive and install Windows7 RTM. Will the boot manager know the difference between v264 and RTM? Once windows 7 RTM is.. ahem... activated, I will move all my settings and programs over from my D drive. Then I will format drive "D" and add it to C, or keep a smaller partition "D" for back ups. I use EASEUS Partition Master Does anyone see a problem with my thinking here? Thanks, Mrwirez PS Great site! I posted this in the wrong section earlier.
