I am using Z97M-plus motherboard.
So i downloaded the ethos 1.2.5.iso and then use HDDRawCopy1.10Portable to copy to pen drive and HDD.
I can entered my motherboard bios, and set the pen drive to boot,
but after that, I see only "_" underscore on top left on the screen, and no text appearing.
keyboard numlock is working, i assume is not hardware problem.
I didn't use any GPU, use only the mobo inboard gpu to boot.

Anyone encounter this problem before?
Tried with HDD 1.0TB, not working,
Tried with eth 1.2.4.iso not working as well.
