I had to fix one of my usb hard drive. Somehow I got it move onto another usb port that doesn't support the boot. lt took me a while to find the right usb port.
At first I thought the plug died. I keep swapping plugs around. Next I thought the usb wire died. lol
I had a few death screens.
Anyway I got the issues fix.
Thinking about using the old ASUS screen on one of the Chromebook that I have.
