You need another Linux system and a card reader. Attach the card reader with SD card inserted, check output of
lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,UUID
Then you need to mount the 1st partition of the SD card and edit /mnt/boot/ArmbianEnv.txt and adjust there the line reading
rootdev=UUID=e59363f1-765c-4660-9275-4563bb872371
and replace the part after 'UUID=' with what lsblk showed for partition of your SD card.
The above example assumed that you mounted the partition to /mnt, if that differs you need to edit still the respective file (/boot/ArmbianEnv.txt on the SD card's 1st partition)
