After some more investigation and especially after stumbling upon a mail
from Otto Moerbeek from 2020, I found that the problem was a missing 'i'
partition in the disklabel.
installboot(8) needs the 'i' partition in the disklabel to find the EFI
partition, otherwise it will try to fall back to MBR.
After manually adding the 'i' partition, everything went find.
Here is the updated disklabel:
# disklabel sd0
# /dev/rsd0c:
type: SCSI
disk: SCSI disk
label: KINGSTON SA400S3
duid: 09a9344c23abff6c
flags:
bytes/sector: 512
sectors/track: 63
tracks/cylinder: 255
sectors/cylinder: 16065
cylinders: 14593
total sectors: 234441648
boundstart: 1024
boundend: 234441615
16 partitions:
# size offset fstype [fsize bsize cpg]
a: 230692352 1024 4.2BSD 2048 16384 12960 # /
b: 3748239 230693376 swap # none
c: 234441648 0 unused
i: 960 64 MSDOS
installboot(8) works as expected now:
# installboot -v sd0
Using / as root
installing bootstrap on /dev/rsd0c
using first-stage /usr/mdec/biosboot, second-stage /usr/mdec/boot
copying /usr/mdec/BOOTIA32.EFI to
/tmp/installboot.AfBA3OfNsR/efi/BOOT/BOOTIA32.EFI
copying /usr/mdec/BOOTX64.EFI to
/tmp/installboot.AfBA3OfNsR/efi/BOOT/BOOTX64.EFI

Hi,
I have trouble with installboot on a small embedded amd64 system.
I get the following error during sysupgrade and also when I run
installboot manually: installboot: no OpenBSD partition.
You can find the output of installboot, fdisk and disklabel below.
I also attached a full dmesg.
I initially installed with 7.2 and I just upgraded to 7.3. This should
be a GPT install but installboot seems to find an MBR, maybe this is the
source of the problem.
If possible, I would like to be able to fix this problem without
reinstalling the system.
Do you have some idea what's going on?
Best regards,
