I bought OPi 3 with 8 GB emmc, installed Armbian for OPi3, buster version, in the instructions I found a way to transfer the system to emmc - the nand-sata-install command. Then my actions:

1. Without apt update/upgrade try run nand-sata-install. There is only one option in the window that appears - Install/Update the bootloader on SD/ eMMC. Ok > WARNING > ok > done > ok. Reboot without sd > OPi3 not booted.  Nothing changed.

2. apt update/upgrade, try run command. Only one option - Install/Update the bootloader on SD/ eMMC. Ok... Nothing changed.

What do I do wrong, maybe the version is not that, or do you need to download something? In the instructions immediately after starting and Running This Command offers three options.

Oh, sorry, I found a problem and solution, moderators, could you please delete this topic, it only litters the list of topics.

Sure we could do that but if you would share the solution of your problem it would be even better because others could find the topic and how you solved it even if it was a trivial issue
