I am attempting to partition my hard drive so I can dual boot Vista and Windows 7. Ive tried to partition my hd once before and it said it couldn't be formatted completely, after about 96% complete..So now I don't know what to do..On my C: drive it says I have 217.83gb NTSF..It says healthy (system, boot, page file, active, primary partition) it also has a Recovery side which is (E:) 15.00gb healthy (primary partition) then it has 55mb (healthy, EISA configuration)..how much should I shrink the volume for Windows 7?? All I did the first time was shrink what it had in the 'how much do you want to shrink box..Which I knew was more than 40gb that Windows 7 can run on comfortably, so I was told..I don't know what I did wrong but obviously it was something..Can anybody help me?? Thanks in Advance.. WH
