You must still have full options, with how you setup your winnt.sif. If you get this menu: 1. To setup windows XP now, press enter. 2. To repair a Windows XP installation using recovery console, press R. 3. Quit. If you select 1, then you can repair or install fresh without repair. Or you can select 2, then enter diskpart at the cmdline, just like the old fdisk. And delete/create partitions, format etc. Are these the options that you are receiving?
