I've flashed image on USB stick but my rig wont boot to it, is says bootable drive not found. Same rig with same USB drive flashed with SMOS worked, any ideas why this wont?
What program are you using to image you USB key?
If your using a Windows build computer; I would use hddrawcopy for v0018.
Also depending on your motherboard; you may need to disable bios settings related to: secure boot, or TPM.
