Hi!

 

Can I install a clean Armbian from within Armbian, without flashing a SD-Card?

 

One idea: After installing Armbian, I used the NAND-SATA-install to copy my files to a harddrive. But on the SD-card there is still the old system. Can I switch back to boot the SD-system?

Can I switch back to boot the SD-system?

Yes, you can. Mount your sd card somewhere and edit /path_to_your_sd/boot/boot.cmd . Change the line "root=", from whatever it is (root=/dev/sda, i assume) to this:

root=/dev/mmcblk0p1

You can also check if your sd card is mmcblk0, first. In some cases it can be mmcblk1. Generate new boot.scr :

sudo mkimage -C none -A arm -T script -d /path_to_your_sd/boot/boot.cmd /path_to_your_sd/boot/boot.scr

and reboot.
