First thanks for all the work.
I'm using my own build machine
cpu:intel i3-6100
mb:gigabyte h170m-d3h
ram:kingston 16g ddr4-2133
psu:corsair rm550x
hdd:4*3tb seagate nas hdd
I used the usb boot image for bare metal in UEFI mode in first page on a sandisk ultra fit usb drive
and edit the grub.cfg
but just "Welcome to GRUB"
and i can't even see anything in the assistant
is lack of driver?
thanks for helping
