I want to upgrade Win 7 beta to newly bought final version (Home Premium). I also have 'Boot from old windows' choice with XP SP3. The question is, is it safe to upgrade/install Win7? Will it recognize XP MBR saved by beta and preserve it for future use?
P.S. Also, the installation will be from W7 disk, as I cannot boot into W7 beta anymore (stuck in infinite "repairing" process).
