Fwiw I've had pretty good experiences with getting LLMs to do the gruntwork of porting Bash to Python in my case. It's a translation task after all.

I threw the code away again in the end. We didn't have that much of a need for non-UEFI targets, but I was experimenting at the time with booting on some cloud x64 machines that lacked UEFI support.

If I had to do it again, I'd probably just write a loader myself. It took about the same amount of time to fight grub as it would have done to smush together a basic GPT / FAT / jump chain.
