I did a first install on an external SATA connected drive and this one
I then installed an internal 2.5" hard drive inside the enclosure of
the Open-Rd and tried to install debian on it using the same
I think the 2.5" HDD had an EFI partition to start with. Then the
install goes fine but at the end the U-Boot only sees the GPT with
partition type EE.
When I boot on the external hard drive into Debian, I can see the
partitions on the 2.5" drive inside but Uboot cannot boot from them.
When doing fdisk/cfdisk from the other debian install, I get a warning
about GUID partitions and that I should use parted - but that is not
my problem :-)
I also connected the 2.5" drive to a regular PC and did a gptsync.
Then Uboot can see the partitions but the boot parition was empty, so
I am not sure if this is an installer problem.
Anyway, at the end, I erased the GPT partition with dd if=/dev/zero
of=/dev/sda bs=1M count=50 - I know this is an overkill and
repartitonned using fdisk.
It was late yesterday so I didn't finish the whole thing but I am
expecting that should work - there is no more EFI stuff on the disk.
I think the existing EFI partition did confuse the installer but I did
not keep the installation logs.
