Hey,

i'm using a new Sony VAIO laptop for two months now and I really often tried to boot Backtrack on this laptop, but that wasn't successful. I think the problem is the UEFI system, what is preinstalled on the hardware. I turned "Secure Boot" in the options off, but it always says "no operating system". The only reason to boot from CD or flash drive is setting the bootmode to legacy every time. That wouldn't be a problem at all, but I would prefer a dual boot with Windows 8 and Backtrack 5 R3 under UEFI. Is there a reason for my problem?


(if you found mistakes you could correct them )

Thank you!
