Trying to help another district - same Acer Aspire V5-131 we have, the ubermix install (option 1) asks to configure the primary and secondary hard drive. Never seen any mention of a secondary drive.
When the user answers yes and the process completes, the system boots to a purple screen and hangs.
He also can no longer mount the USB key.
Any thoughts? Could it be seeing the USB as the primary or secondary?
