problem installing win 7 on debian machine

[Johan Thallauer]

Hi im trying to install windows 7 from my usb drive on a mchine that already 
has debian only installed on it and I keep getting "invalid partition table" so 
is there something that I have to do in debian to fix this?(I love it when 
copy-paste also copies thte dont styles, so stupid....)
see my question here:
