BIOS boot vs UEFI boot

[T-Aoki]

UEFI has evolved significantly since my 2012 version so I stick with MBR on this machine.

At least some PCs with legacy BIOS allows GPT boots.

Note that, as I've described in the above-linked page, at least old ThinkPads need special care on partitioning. And now, gpart(8) has lenovofix attribute to cope with it.

I refuse to use Secure Boot

Me, too.

It wasn’t so long ago that some users preferred BIOS boot over UEFI boot for its robustness and lack of issues. I’d like to know what the situation looks like today. What would you choose for a system on which only FreeBSD is installed? Is BIOS boot still considered less problematic than UEFI boot?

I install each FreeBSD in BIOS+UEFI setting after choosing Auto (ZFS) option - but these times I mostly (like 95%) boot with UEFI - I just keep BIOS option as fallback ... not sure if that helps.

I had BIOS+UEFI configuration, too, for several installations for testing UEFI boot codes (first smh@'s and later Naomichi Nonaka's) for emergency legacy BIOS boots. And I'm still using the latter (my variant), now with UEFI-only configuration.

Notably, UEFI mode is the only mode that allows you to boot with graphics on a bhyve VM without using remote desktop software.
