Dear fellow Fedora users,

I am trying to back up/clone/save an image of a raspberry pi 4 machine running Fedora 39.  It reports an error that GPT/MBR mismatch :

This disk contains mismatched GPT and MBR partion:  /dev/mmcblk0

I am doubting what to do, as I have tried to clone Fedora raspberry pi installations and have not succeeded.  How can I tell what type it is ?  


The disk must be MBR so that the RPi 4 GPU can boot the system from the files in the MSDOS disk.
And I can run with the 6.6.6 kernel without error.



user@debian:/media/mmcblk0p2/home/olivares/Downloads/kerTeX/Documents/mptmp$ uname -a
Linux debian 6.5.0-3-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.5.8-1 (2023-10-22) x86_64 GNU/Linux
user@debian:/media/mmcblk0p2/home/olivares/Downloads/kerTeX/Documents/mptmp$ exit
exit

That says the system is debian not Fedora.

Please confirm exactly what you are doing.
