iMac OSX Lion Bootcamp & Sysprep Problem

[DEfrostphone]

I have a problem with bootcamp on a new Lion iMac, installed Windows 7 64bit not problem but when I run sysprep or mysysprep it reboots and starts to setup the pc but then comes up with a error “Setup can not continue setup will restart after a reboot” the computer then reboots and other again.

 

The answer file, I have been using for both mysysprep & sysprep works on a normal PC and I have even tried just run sysprep with no answer file and it still produces the same results. Has anyone got any suggestions.

 

Thanks
