I have had a surface pro for a while now and I have decided to try and boot from USB on it. It won't boot from it.
I have tried an external hardrive with Windows Vista on, a Windows 98 Microsoft-dos boot disk and even a Windows repair disk on an external disk drive. All of these devices boot on everyone of my computers except my surface.
I have tried disabling secure boot keys in the BIOS and I have tried booting via Windows 8 advances options and by holding down the bottom volume rocker at start up. None of it works.
