hello. I've been using a dual boot system for two years with xp-pro and win 7-pro 32bit os. I mostly work in XP because of old software that will only run well in that os. But I'm getting to the point where it's time to replace mobo/cpu/ram and am trying to migrate to win7 predominantly. The new hardware will make it easy to run win7-64. Before I invest in the hardware I want to run a trial ver of win7-64 on a new partition. If I install it on the same hd that already has xp and 7 partitions, will the new w7-64 partition now contatin the master boot loader for everything? Should I run easybcd from there? Thanks for the help.
