          I’m pretty sure there’s definitions of this elsewhere in the forum or in documentation/wiki that is more thorough.

          But here’s a quick overview

          Exit Types

          EFI exit type

          • Used for computers in EFI/UEFI mode. This is used in all modern computers for the last few years
          • Setting the efi exit type is the behavior fog will use when ‘booting to hard drive’ the pxe menu was booted to via an efi/uefi boot option

          Bios

          • For older computers or computers using legacy/bios mode
          • This defines the behavior when the fog boot menu is accessed via a legacy/bios boot option and then ‘boot to hard drive’ is selected

          SANBOOT

          • Works for bios exits by issuing a sanboot command to boot to hard drive
          • Doesn’t work with efi in my experience
          • This is a good standard default for bios exit type

          GRUB

          • Uses a grub boot loader hosted on fog to attempt to boot to the OS
          • This can work with efi or bios, but it isn’t always super reliable in my experience. It’s a good option to use when troubleshooting a computer that is having trouble exiting the fog boot menu to get to the hard drive

          GRUB Sub options

          • The sub options like first_HDD, first_windows etc. attempt to do exactly what they say. They are just GRUB bootloader options

          rEFInd

          • This uses a tool called rEFInd, which re-finds all efi boot options
            • The fog refind conf just boots to the harddrive/os option it finds. It can be configured to give a menu of options
          • This can work with bios options in theory, but it’s meant for EFI exit
          • This is a good default for efi boot options

          Hope that helps.

          Have you tried the FogApi powershell module? It's pretty cool IMHO
