I have purchased a copy of Windows 7 Professional Edition. I currently have Vista 32 Bit Home Premium installed on my C drive with various programs, utilities etc. As the C drive only has a capacity of 34GBt I want to install a 64 Bt Windows on a clean formatted 1TBt Samsung F3 Spinpoint drive but fear wiping the C drive and loosing all my programs etc. I don't want to backup the C drive if avoidable and I am unsure how to proceed. I know that "dual booting" is feasible but how to do? Any information would be appreciated.
