I am not sure I am following you here. The EfiShell is an application. You can use 'eficonfig' to add/delete boot entries for EFI, which will appear on a menu. > And EFI-based secondary > bootloaders like rEFInd could let us choose them in a graphical menu, > efibootmgr could change their order or reboot into a non-EFI flow... I'll have to check rEFInd, but I think it looks for PE/COFF binaries? Thanks /Ilias
