Many thanks for your report.

Indeed there is a bug in the script, which is able to detect the root entry on Odroid XU4 correctly (https://github.com/MichaIng/DietPi/blob/master/boot_xu4.ini#L11) but not on C2 due to the leading " double quote character in front "root=": https://github.com/MichaIng/DietPi/blob/master/boot_c2.ini#L126

Fixed with: ed19661
Changelog: 82fb47a

What is that the on your Odroid now? Is it still running after you exited drive manager? Before rebooting, apply this change manually to boot.ini:

# Store the content of the old entry in a variable
rootfs_current=$(mawk '-F[" ]' '{for(i=1;i<=NF;i++) if($i~/^root=/) {print $i;exit}}' /boot/boot.ini)
# Verify that it is valid
echo "$rootfs_current"
# The output of the above should look like "root=UUID=24d16755-9c44-4541-b2ea-0fa717ad2bec" just with a different a different UUID.
# If so, apply it to your boot.ini
sed -i "s#$rootfs_current#root=UUID=24d16755-9c44-4541-b2ea-0fa717ad2bec#g" /boot/boot.ini
# You can then verify that is has been applied correctly
cat /boot/boot.ini

It should then look like here: https://github.com/MichaIng/DietPi/blob/master/boot_c2.ini#L126
but with /dev/mmcblk0p2 replaced by UUID=24d16755-9c44-4541-b2ea-0fa717ad2bec.
