My test install really isn't going very well. Fired up an install on a new little test desktop, and installed it to my USB drive. Install went fine. Boot to the USB Drive and it gets to Grub and loads the 32/64 bit option, but a few seconds in to loading it flashes a screen and reboots. Boots into safemode fine. Found a thread on here with a very similar problem, and one guy mentioned it wasn't able to find the root drive or something. So I installed it to the hd on the box and its working fine. Of course I want to use the hd for tests and the usb disk for the OS. Anyone have any fixes for this?

Thanks
