I think I f-d up. I was trying to install archlinux on my new device and accidentally partitioned and installed onto the wrong card... they were both 32GB! Who woulda thunk it? Anyway, I don't think I can boot the efi firmware now since I cannot get to the splash page, it just goes straight to my GRUB installation, which also isn't working Any ideas?
It did not; tried twice. I could try a few more times though as the udoo screen was only up for half a second
Apparently I didn’t try hard enough, since I slammed esc a few more times after plugging in and it worked. Boots into uefi just fine now, and I got my bootloader running properly as well. Just ignore me
