Something is wrong here. Code ef00 is reserved for the EFI system
partition, yet you have that code on three partitions. You could change
the code on the two Debian partitions, they should probably be 8300 if
they are normal Linux file systems.

It might be a good idea to clean up a bit and get rid of the operating
systems and partitions you don't use. If you need a lot of different
logical volumes within Linux, look at LVM instead.

I *think* ef02 is reserved for the Grub 'BIOS boot partition',
something you should not need with UEFI. I might be wrong, though. 8200
is swap AFAICR, the others I am unfamiliar with.

Right now I can't see any overlapping partitions, but I could be
overlooking something.
