Hello Rebecca,

 Yes, I know. But what should I do next? There is no  "Set UEFI Boot Var"
item in it. You could select different physical drives (but not partitions
of the drives) and network cards (if PXE is enabled), and, sometimes, "EFI
Shell" which is not documented anywhere, and it doesn't work always.

 When I google "ASUS EFI Shell", for example, all results says about
preparing USB stick with EFI shell and such, not about commands and
variables of EFI shell.

 I don't say, that it is impossible, I only could not find good (or any)
documentation.
