I already have Windows Xp SP 3 installed on my hard drive. I am buying another hard drive and am planning to install Windows 7 Professional on it without uninstalling Xp from the first one. So, I had 3 queries. Namely: Is what I'm doing correct or rather should I do this? If I do it, will I be able to access data (obviously not the softwares, just the data) stored in the first drive while working on Windows 7 Professional? If what I am doing is not right, can I uninstall windows from the first without losing my files(again, of course except the installed software)? Thank you to everyone who replies in advance. P.S. Unrelated question but does Intel Core 2 Duo E8400 @ 3.00 Ghz support Windows 7 Professional 64 bit?
