First, sorry for my bad english, i'm french
I tried to make an unattended version of my Windows Vista Sp1
I choise to make a bootable DVD on the first menu
But when i try my ISO with virtual PC, or when i boot from the CD that i have burned, i have this error message:

I tried a lot of time, with version 1.1.6 and the last 1.2 RC, and i always got the same error message
Can you help me ?
Thanx
