I was installing windows 7 onto my new pc using a usb. My motherboard doesn't have boot from usb an option so I set the harddrive boot priority to the usb. It starts and installs fine but as soon as it restarts to finish it boots from the usb again restarting the installation. If I choose for it to boot from the harddrive it says

Verifying dmi pool data...
Error: unknown filesystem
Entering rescue mode...
grub rescue>

And nothing happens from there. How do I get it to finish the install and boot properly?
