For some reason I can't install to 64, 128, or 256GB SD Cards, but when I tried to use a 32GB card it worked fine.
With the larger cards, the install goes fine, but on boot I get the error:
ZitatAttempting Boot From USB DriveKey (C:)
error: attempt to read or write outside of disk 'hd0'
Entering rescue mode...
grub rescue>
I tried the guide https://askubuntu.com/a/1088738, but I get an error every time when I get to the "ls /boot" command.
I also tried with a USB to SD Card adapter and got the same error as above.
Any ideas? Is there a known limitation with the size of SD card used in OMV or Debian?
