There have been known bugs in some firmware implementations here, I'm afraid. See [1] and [2] for examples.

No error reported. OK, that error comes from exactly the code I'm reading in efibootmgr. Calling that command line again with extra "-v" will print more information, maybe. >From experience with other Lenovo machines, you *may* be able to fix this by re-flashing the firmware/BIOS - this typically resets the EFI variable storage space. -- Steve McIntyre, Cambridge, UK. st...@einval.com < Aardvark> I dislike C++ to start with. C++11 just seems to be handing rope-creating factories for users to hang multiple instances of themselves.
