running 24.8.3, and Armbian-install's screen looks like this:
Current root: UUID=117b851b-2be0-4bb7-8572-7edce1ef7375
SD card (/dev/mmcblk1)
1 Boot from SD - system on SATA, USB or NVMe
2 Boot from - system on
3 Boot from - system on SATA, USB or NVMe
5 Install/Update the bootloader on SD card (/dev/mmcblk1)
I have a µSD card inserted and a 4gb eMMC, but it looks like the names of these devices are missing?
