Hey, I've recently got a copy of Windows 7 Ultimate 32-bit and I'm currently running Windows Vista. I got it because I wanted to upgrade my OS, I know I may be been able to upgrade from vista->7 using the upgrade software which Microsoft do, but I didnt want to do that. Well, my current windows vista computer is bought from Dell and running their OEM OS. They have partition my hard-drive so I can restore if I want to. I'm planning to do a clean/new installation of Windows 7 on the hard drive, however I still want to keep the restore part so...If I want to go back to windows vista, then I will have to install it again. I will be backing-up all my data onto a external hard-drive so I can copy all of pictures, documents etc to the Windows 7 part. my question is: How will I be able to install Windows 7 and uninstall Windows Vista, so I can still revert back to Windows Vista (OEM from Dell) in the future if I want. Will I need to delete/reformat the windows vista partition and then install windows 7 over it?? Will this still keep the recovery partition as I have not deleted it? Thanks in Advance
