I am planning on upgrading from XP Home to Windows 7 Home Premium and would like to install two new hard drives with RAID 1 at the same time. I purchased the Upgrade Windows 7 version, not the full one. But I do still have the full version of XP. So I'm thinking that I will have to configure the RAID, install XP on the new drives and then go back and do a clean install of Windows 7. Is there any shorter way to go?
