This issue seems to be pretty common on the web, but I can't seem to get anything to work. Basically, I've created a persistent Arch USB that's set up for mining. It boots and runs fine on my PC and in a VM on my laptop. My PC also has a Gigabyte mb and the drive shows up as GRUB (SanDisk). On the rig however, it shows up as "UEFI: SanDisk, Partition 1" and if I enable Legacy USB I get another entry that just says SanDisk.
Booting from the UEFI just brings me back to my BIOS setup while booting from the SanDisk entry tells me to reboot. I just updated my BIOS and the same behavior is happening. I should be booting with UEFI the same as I was on the other motherboard but for reason this is messing up. Enabling and disabling Mining Mode doesn't seem to do anything.
Thanks for any help you can give.
