I brought an Aspire S3 today to replace my ageing Vaio but I can't get it to boot from my USB drive.
The S3 arrived with Win8 which works fine and sees any USB drive I connect to it. However when I try to opt from a bootable one it just goes straight to Windows.
The USB drive is definately bootable and works perfectly on the Vaio.
I've gone through all the options in the BIOS (Insyde H20) and tried every combination of boot order. When I try the Boot Order key (F12) during POST only the internal HDD shows up.
Is there a known issue with booting from external devices on this device or am I missing something?
(Don't think it helps/makes a difference but the USB drive is a SanDisk Cruzer Blade 4GB, made bootable by YUMI and has 5 bootable OSes on which I need to be able to access.)
