efibootmgr 0.5.4-7ubuntu1 (i386 binary) in ubuntu trusty

 This is a Linux user-space application to modify the Intel Extensible
 Firmware Interface (EFI) Boot Manager configuration. This application can
 create and destroy boot entries, change the boot order, change the next
 running boot option, and more.
 .
 Details on the EFI Boot Manager are available from the EFI Specification,
 v1.02 or above, available from http://developer.intel.com.
 .
 Note: efibootmgr requires that the kernel module efivars be loaded prior
 to use. 'modprobe efivars' should do the trick.
