It’s 2023, Linux has great UEFI support, there is no ONE reason to be using MBR over GPT.
I have to admit, I’m a little surprised someone has a machine that doesn’t support UEFI, because the board I bought in 2012 had UEFI support… 11 years puts most machines into barely being usable in Windows.
While it’s a valid reason, guy has to be working with either some really old or very specific hardware.
The thing is… I think a lot of people don’t know that they have uefi support…
I have had the same windows install and motherboard (AMD is so great with long term socket support) for years, and figuring out how to change my bios and os setting so that I got a propper uefi boot was non-trivial.
Uefi has been a thing for a long time, but it’s not been the default for motherboards afaik. So you have had to go into bios and find the right settings.
