• How to Boot ISO Files from GRUB2 Boot Loader

  See also UEFI drivers that can read a bunch of other file systems (btrfs, ext2/3/4, HFS, ISO, NTFS, UFS/FFS, XFS, ZFS, etc):

  * https://github.com/pbatard/efifs

  The UEFI spec specifies (§13.3) that firmware is only required to read FAT32/16/12, which is generally why your /boot/efi is VFAT/FAT32.

• Is exFAT bootable?Can I boot WinPE with exFAT?

  In theory you would still need a FAT32 efi 'stub' partition with the exFAT filesystem drivers which you have to load before loading the WinPE loader (bootmgfw.efi).

• How do I configure the refind.conf and refind_linux.conf (and or config.yaml (for ZFSBootMenu)) files properly when installing Arch Linux with ZFS Native Encryption?

  I am pretty sure that that I am doing something incorrectly with the configuration files for the rEFInd bootloader, but everything else should be correct. However, as I write this, I barely realized did I not use the following commands recommended from the "Usage" section from the aforementioned website where I downloaded the zfs_x64.efi driver file for rEFInd:

• Grub vs Systemd-boot --removable question
  1 project | /r/archlinux | 22 Jan 2023

  I found the drivers here https://efi.akeo.ie/ . Which means, that any EFI bootloader able to load them will be able to use them. They are not for bootloader, but it is the firmware which will use them. As i said, i am little bit afraid that it will not work on any board as some manufacturers have pretty buggy firmware when talking about infrequently used features. Also i am bit unsure they will work with secure boot as they are gpl3 thus will be never signed by Microsoft and i don't know what UEFI requirements for drivers are in this regard.

• Why use a bootloader? Just boot directly into a unified kernel image

  Even for those using systemd-boot with custom efi drivers to provide functionality, it's worth noting that those drivers are being developed downstream of GRUB.

• Latest grub update on arch distros seems to cause boot issues

• So why do so people still use GRUB?

  I think you can also add btrfs filesystem support for sd-boot by including the EFI drivers for it on the EFI partition instead, from https://github.com/pbatard/efifs/releases I think. Haven't tried it myself though.

• Is any ESP filesystem other than vfat supported on coreboot? (lemp9)

• Fedora considers deprecating legacy BIOS

  EFI doesn't actually mandate FAT for the system partition. The system partition can be any filesystem that the firmware supports.

  Of course, pretty much all EFI implementations only support FAT, so it's a bit of a moot point; the only one I'm aware of that supports anything else is the one on Intel Macs, which also understands HFS+.

  You can find a huge selection of EFI filesystem drivers at https://efi.akeo.ie/ but they're derived from GRUB and hence GPL, so don't expect the likes of American Megatrends to be bundling these any time soon.
