QuoteThe FAT TYPE partition is required and has been since the get go. Though the size requirements continue to grow. I go with 500Mb. You also have to flag it EFS and check the bootable flags as well...
QuoteYour BIOS not allowing a Legacy boot environment is kind of surprising to me. Should be a spot to disable Secure UEFI, then enable CSM Boot.
QuoteBoot Order: Ensure the Debian entry is not the only EFI boot option available. There might be a way to manually add or prioritize boot entries.

You got it. Debian has a signed EFI key somehow and Arch also will do an EFI boot and install, Last I heard or read (i.e. more than a couple of years have passed) reFind used Debians signed key.

Your BIOS not allowing a Legacy boot environment is kind of surprising to me. Should be a spot to disable Secure UEFI, then enable CSM Boot. (i.e. Legacy boot mode) After doing this you should also be able to boot to any USB/CD ISO you choose.
I'd for sure delete the signed MS EFI key if your able. Totally personal choice I suppose but I consider it beneficial to all future installs on that laptop as long as MS isn't in your vocabulary!
That's it, all I know and remember without some actual digging. From all the digging and research back then, I learned it was futile of me!!! Don't end up in a rabbit hole VastOne!
