http://ubuntuforums.org – Computer: Toshiba P870 Laptop Drives: 2x 500 GB SATA USB Boot: XUbuntu 11.10 Live USB First attempt: Blocked by 'Secure Boot'...powered down by itself 1 minute later. Second attempt: 'No bootable device -- Please restart system' (With the 750 GB drive with Windows on it, that was a given, but the USB stick's activity light didn't even try to light up this time) Attempts 3, 4, and 5 using the other USB ports, one by one: Repeat of second attempt. No BIOS logo, just black screen until the above results. What can I do to get Secure Boot to disable itself, and then recognize the USB stick as boo (Hardware)
