I have read through the curtin and autoinstall documentation and can't wrap my head around why this autoinstall script is working on my development laptop but not my vbox install (ver 7.0.8 on Ubuntu host). At first I thought the problem was references to /dev/mmcblk0 (virtualbox uses /dev/sda) but after making a number of different configs I don't think this is actually the problem because of the error message this gives. The is autoinstall config did not create needed bootloader partition

My theory is that this autoinstall works on the laptop because the laptop is UEFI but not on Virtualbox because it is not. I have found some suggestions elsewhere on how to make an autoinstall that works for UEFI work on MBR, but none that are able to do both.

Is that the problem with this autoinstall partitioning layout? Is there any solution? I can't use the built-in layouts (lvm etc) due to this project's specific requirements. I realize I could change the Virtualbox settings to EFI boot, but this ISO will have to be installed on a wide variety of machines some of which may not support EFI.

Here is my current partitioning layout, which is working on a laptop with a device at /dev/mmcblk0

How does this script need to be modified to work on any system? And yes, the /boot partition really does need to be that large for this setup.
