I’ve said this multiple times in other comments, but what would be amazing is a linux-installer.exe that shows the normal installer wizard with non-techie, beginner, and advanced options that allows installing linux from windows and booting right into it.
The ultimate goal would be for the desktop environment to have a windows theme by default, have all the alternatives installed for previously installed software with desktop icons that look the same, and all files to be where they were previously. That way you could just say “go to https://windowsupgrade.com / https://linux.install and run the installer” to anybody non-technical and have them running linux in under an hour.
It should be so simple and unassuming that people don’t even realise they installed linux. If they message back “I ran it, but I’m still on windows”, that’s a success.
That would lower the barrier to entry significantly. It doesn’t address the issues with the bios but someone mildly adventurous would have a much easier time going forward.
I think something like that would have to be sponsored by and maintained by a big distro though. I’m afraid if it was a community effort the amount of bikeshedding would stop it before it even began.
It would completely eliminate the bios issue, would it not? It would prevent them from ever needing to enter the bios at all.
