I have the same problem, and it wont help waiting! have tested it 4 times, and watied for at least 3.5 hours, ends up at a black screen whit the mousepointer! Someone heard about succeding?
Ive managed to solve this problem now!
I have a Dell, and all you need to do is to install the ACHI-drivers for the hdd before you choose which drive you gonna install windows on!
and as i said, for me I have a dell, and i got a Drivers and utilities DVD where you can find the driver for the hdd!
Hope it solves your problem!
