there is nothing to doThe other day, Elementary announced elementaryOS 6 preview builds for the Pinebook Pro. I went ahead and flashed an SD card with a build image to try it out. Instead of booting to elmentaryOS on the SD card as the system should have, it booted to Manjaro. While a quick restart from Manjaro caused the system to boot from the SD card, I figured it must be time to upgrade the bootloader, U-Boot. As it turns out, it was time because this solved my boot issue.
This tutorial provides instructions for updating the Pinebook Pro’s bootloader from Manjaro Linux.
First, ensure the system is up-to-date.

Flashing to the wrong device could destroy your data. If you have an SD card connected, you might want to unplug it to be safe. |
