Your best bet is to probably use System Restore.

Pop in your Vista install disc, startup your computer and boot to your Vista DVD. Click 'Next" when the installer starts up and "Repair your computer". Follow the choices and select System Restore. Restore your computer to a day or two prior to the time of your OS X theme installation.

i m not sure the disk problem or wat.
because cannot booting into vista dvd,it just it just skip the "press a key to boot cd".

You have to go into the BIOS (Hold DEL during initial system start-up screen) and set the first boot device as the CD/DVD-ROM. Otherwise it will skip the boot to CD process because it detects an OS on the hard disk.
