Legacy or UEFI Boot?

[cboettig]

Curious if folks recommend Legacy or UEFI boot option in BIOS? (When running A18 BIOS). Do both options work? Is there any reason to prefer one over the other?

I have always been on UEFI, since the beginning. Easier for firmware upgrade, as you can access /boot/Efi from the OS.

Once switched in BIOS, and you OS installed, AFAIK, you can switch one or antoher, because of GPT. Legacy BIOS needs MBR & Co.

Thanks. I've switched to UEFI. Surprised that I no longer get any screen input (e.g. no DELL logo at startup with the 'hit F2 to enter BIOS) menu, it just boots straight up. Is that expected? This is mostly fine, but It's not obvious to me now how I would tell the system to, say, boot from a bootable USB to do a fresh install...

Nope, I have the dell logo at boot here.
