Getting the UEFI shell on boot and the mistake I made that caused that

I mistakenly wrote an x64 Ubuntu iso to my SD card.

When I tried to boot my Orin Nano off it, I got a UEFI shell prompt. That was not something I’d seen before, which confused me, and googling didn’t really come up with any good suggestions.

Only when I went to rewrite the SD card a second time did I notice I picked the wrong image file the first time and, of course, picking the right image worked fine.

So, I leave this here so the next person who makes a similar mistake has something more helpful in their search results.


Actually it no needs to be surprised. Even if you didn’t write the wrong image, default bootloader on jetson orin series is UEFI… maybe you just didn’t notice because previously there is always correct boot drive…
