Windows 7: Help: use a USB drive to boot a VHD stored on HD

Hello all,

I've been working on this idea for about 2 weeks now and I've made some progress but not nearly enough. So I figure its time to ask the experts.



We are holding a lan party at my school but we aren't really allowed to touch the machines. They are all running windows 7 enterprise. My goal is to copy a VHD of enterprise 7 to the C: drive of each machine the night before the lan party and then use a USB drive to "start" the vhd.

So far I've gotten a vhd created and run sysprep with /generalize and oobe. Then I used easyBCD to make the usb drive bootable and pointed it to the vhd file but it always fails when it gets done installing the device drivers. Something about unable to configure boot configuration.

Are there any good walkthroughs on doing this or is this not really possible. We are being as ethical as we possibly can be and have enough licenses to try this on a few machines. I really can't modify the machines much other than copying the vhd to them.

Thanks for the help.
