Autoinstall ubuntu (programming.dev)

I want to automate the installation of ubuntu-desktop v24.04 hybrid.iso using autoinstall.yaml. I found that the steps for this are described here: https://danielpersson.dev/2023/08/07/looki-looki-no-hands-automatic-install-of-ubuntu-server/
https://youtu.be/DtXZ6BMaKbA

After making the necessary changes and repacking the ISO, I ran into a problem:

  • when flashing the image with balenaEtcher, it shows an error that the partition table is missing;
  • if I still write the new image to a USB stick, it doesn’t contain an MBR/GPT partition table and therefore won’t boot on a PC.

My question is: what am I doing wrong? Do I need to manually specify the partition table when repacking the ISO, or is the cause something else?

Thank you in advance)

Any particular reason for not using PXE?
