This also includes the EFI default/fallback loader at /EFI/Boot/boot*\&.efi\&. An gummiboot entry in the EFI boot variables is created, if there is no current entry\&. A created entry will be added to the end of the boot order list\&. .PP \fBgummiboot install\fR installs gummiboot into the EFI system partition\&. A copy of gummiboot will be stored as the EFI default/fallback loader at /EFI/Boot/boot*\&.efi\&. An gummiboot entry in the EFI boot variables is created and added to the top of the boot order list\&. .PP \fBgummiboot remove\fR removes all installed versions of gummiboot from the EFI system partition, and removes gummiboot from the EFI boot variables\&. .PP If no command is passed \fBstatus\fR is implied\&. .SH "OPTIONS" .PP The following options are understood: .PP \fB\-h\fR, \fB\-\-help\fR .RS 4 Prints a short help text and exits\&. .RE .PP \fB\-\-path\fR .RS 4 Path to the EFI system partition\&.
