Unable to boot to newly installed Linux OS
My new board arrived a few days ago. I was able to boot to USB stick with Linux Mint. I successfully installed Linux Mint. When I remove the stick and attempt to boot to the newly installed OS, the device goes straight to boot menu and then BIOS. It boots to the stick correctly every time. I installed the OS multiple times - the second time choosing UEFI.
I checked the boot menu settings and they look fine. This is my fifth Up board and first time that I have had issues. However, this is also the first Up2 board.
Any known solutions - other then returning it for a replacement?
