Bug Description

I have a device that has a 64bit processor but need a 32bit UEFI for Installation.

Please add possibility to change/modify UEFI to the own need.

Add an UEFI section to Cubic where you could tick the UEFI you need. e.g. 64bit, 32bit, ARM, RISCV (RISCV seems in development)

https://packages.ubuntu.com/focal/grub-efi-amd64
https://packages.ubuntu.com/focal/grub-efi-arm

This looks a little more complex than what you are stating.

I think you need a distribution that supplies a bootia32.efi file.
I couldn't find such a file with the available Ubuntu packages.

If you can list out the exact steps, using packages from the Ubuntu repositories, I may be able to incorporate it into Cubic.

I did find...

  https://askubuntu.com/questions/775498/ubuntu-on-32-bit-uefi-only-based-tablet-pc

However, the accepted answer in the last link states "Canonical doesn't offer a bootable 32-bit ISO that has an EFI bootloader." The approach described requires you to download a Debian ISO image to get the correct 32 bit EFI.

AdlerHorst,

Based on the following...

    https://askubuntu.com/questions/775498/ubuntu-on-32-bit-uefi-only-based-tablet-pc

I suggest you download a copy of bootia32.efi.

Before you click the generate button, copy this file to...

    <Your Cubic Project>custom-disk/EFI/BOOT

Then generate the custom ISO in Cubic as you normally would.

I think this all you should have to do.

Unfortunately, I can not test this because I do not have a 32bit UEFI machine to test with.

Please let me know if this works?
