I just bought a Sony Vaio VGN-A270, it came with Windows XP professional and no recovery disks. I would like to load Windows 7 on it, and have a Win 7 Professional DVD. Does this sound about right: Since the Bios is not showing as having SLP 2.1 (or any version for that matter), I am going to need to get a modified bios from someone to have any hope of activating? If I had to go back to Windows XP (I have the Windows XP sticker on the bottom of the laptop which I assume I could use), I would need to get a DVD with Windows XP Professional? (I do have a Windows XP Home Upgrade DVD but didn't think I would be able to use with the key I have?) Does this sound about right? Suggestions? Thanks!
