Well, people say that downgrding from Vista to XP with Windows.old is impossible. Well, Wednesday, I decided to confront this statement. I took Windows.old, stuck it in F:\ and went with the Windows XP setup. I formatted the C: partition and I hard resetted. I copied Windows, and all the folders via WinPE (Could have been done in Recovery Console) and I went in the console after. I copied all the boot files in the C:\ directory and I typed fixmbr and fixboot. Within 4 hours (Transfer of files is long!), there we go. I am back in, the way I left it.
