I assume I’m overlooking something obvious, but I can’t get an OS to boot off USB.
I flashed a SD card using the libretech flash tool and installed the card, but when I boot up, I’m getting the grub fallback menu screen indicating it cant find a valid os on the USB stick. I used balenetcher to install the ubuntu server image from the libre downloads page. The USB stick doesnt appear to be corrupt in any way. OS appears to be on it and I can see the vfat EFI partition if I stick it in a regular windows PC.
Goal is to get it booted off the USB so I can start carving up the SD card to try to build a gentoo install on it.
