Dell Vista, Repair Your Computer by pressing F8 - fail

Hi Mark Wharton, are you there?
Can I use the procedure you were giving to DGIBSON?
I have a Dell Vostro loptop with Vista and when i go to Advanced Boot Options and press F8, then i highlight Repair Your Computer and press ENTER, it leads me to normal login window, instead to „Factory Image Restore.” Should i run the bcdedit /enum all: ?
