Did you save a backup image of Vista, or save the Vista Recovery partition and will it still run from the hotkey given at boot?
If not your options if it's factory preinstalled are to order Recovery disks from OEM or find a Vista installation DVD to clean reinstall with Product Key on COA sticker using these same steps: Clean Reinstall - Factory OEM Windows 7
Or you can buy Win7 upgrade version.
Alas, I deleted my windows.old directory.
