USB works under any system but not for boot. I tried everything possible from the oustide.
So please do not ask me if some options is activated in the everything, i also tried all BIOS.
I also opened it and tried to unplug/replug the connections, clear CMOS and things like that...
This looks obviously like an hardware problem and i can't get any support from the brand or seller.
Once my external HD was connected and it appeared in boot menu, but never again.. Just thought WTF..
Of course my USB keys (two from different brand) or HDD are bootable, they worked on all other PC around.
