How do I access UEFI Corebox 5th? А few clicks of esc does not work 
can you tell me your serial number so i can ask tech?
Thanx! I’ve already figured it out.
To access UEFI it needs to press ESC several times, but very quickly and at the very beginning of the OS boot.
There are very few settings in UEFI
oh that is great, thanks for telling because i was about to ask
