Answer #1
format your Drive where u install win7. then install vista this drive. (10GB Space Minimum) NTFS Format.
Answer #2
I doubt if you’d be able to format that drive during the setup of Vista cus it happened with me once that when i was downgrading from Vista to Xp, the XP setup couldnt remove Vista files. Still try and do post here the outcome, as even I need to downgrade my desktop to copy some data.
Answer #3

Answer #4
format it using win7 dan install vista..
or Restore System to last working date..

Anyone that helps you install Vista must dislike you =/
You need to install Windows 7. Vista is total crap!
Back up your data, insert windows 7 install disk, format HDD, then install…
