I managed to get it done, on top of your advise I needed to change the UUID as well in the fstab

Hi Nico, thanks for your help. Sorry to answer only now, I needed to wait 24 hours to be able to write again. What you describe is what I did blkid showed for /dev/mmcblk1p1: UUID="719e2259-339c-4a64-8012-cdd30ffc7dfc" This UUID was the one mentioned in /boot/armbianEnv.txt And I changed it to the UUID of /dev/sdb2: UUID="bd07f3d4-1caa-443d-b91a-07e4057b41f6" didnt work

Unfortunately this is not working, I changed the rootdev UUID from the current one of mmcblk1p1 to the one of my sdb2 in /boot/armbianEnv.txt using nano. When I reboot, board is not booting at all now. I will flash the SD card again.

Good evening, Is it possible to "re-use" the system on SATA ? And how would I do that. I use a HC4 with SD card, a SSD and a HDD I flashed the SD card with Armbian_20.11.1_Odroidhc4_buster_current_5.9.12.img.xz then used armbian-config to Boot from SD - system on SATA. (sdb2) also I installed PiHole, OMV ... Due to an power failure the HC4 was not booting anymore. With a newly flashed SD card its booting again, but of course its not using the system on sdb2 When using armbian-config it would erase by sdb2 before Could I somehow use the system which still should be on sdb2 instead of starting from beginning? thanks for your help best Regards Igge
