> That's not a feature I have any intention of using Fair enough, but it is a security feature I can use to harden my system against attackers. Several Linux-distros support this OOB these days. But if you're not interested, no pressure. Everything works fine without it. > Purely anecdotally/ranting, my only real experience with EFI was trying to boot from a USB stick on someone's machine (to try and recover some of their data, if I recall). I couldn't figure out how to even get a menu or anything, so I gave up. EFI is different for sure. I can't say I blame you for not wanting to read up all about it[1] when you had other stuff to do. That said, EFI is conceptually and practically much simpler than traditional BIOS boot. It doesn't rely on magic bytes being written in specific sectors, it doesn't put a limitation on boot devices or types. (Overly) simplified: It just says that if your medium of choice contains a file a \efi\bootx64.efi on a FAT-partition, your machine will be able to boot that thing with no further action required on anyone's part. As such creating a bootable medium involves 1. having the right FS-type, 2. copying the files. I haven't looked into OpenFirmware so I can't really compare, but compared to traditional BIOS I find EFI conceptually much simpler, much more manageable and to top it off much more secure. I'm happy. [1] https://www.happyassassin.net/2014/01/25/uefi-boot-how-does-that-actually-work-then/ https://www.happyassassin.net/2014/01/25/uefi-boot-how-does-...
