what i know is that vista doesn't need a boot disc to run setup. it is created to be bootable. so what you will have to do place your vista disc to your CD/DVD drive, restart your PC and it leads you to vista setup.I have a new Hard drive I have managed to get initialized, formated and partitioned, ready to go. I also have Vista Ultimate on this pc, and have copied it to the new HD. How do I get a Vista boot disc so I can boot the new HD and run setup? or do I need a boot disc?
