Just some insight I have been around computers all my life.
If I install to hdd (Install goes with no errors) it will not boot.
If I install to usb thumb (Install goes no errors) it will not boot
If I install to usb hdd (install goes no errors) it will not boot
(When I say not boot it does not see the drives)
On the Usb thumb and usb hdd I get error
/dev/disk/by-label/root does not exist
I even set raid controller to raid mode and HBA no luck
So I am out of ideas for this project.
