I do not have a EFI shell on that type of laptop, not to know about it. I can access the firmware setup and already performed a reset and switched back to default settings. No effect. I just downloaded the newest CURRENT mem stick and extracted both boot1.efi and loader.efi and installed those into the ESP as described, setting the efibootmgr env accordingly. Still the same error. It seems that there is indeed no EFI/UEFI shell. There are Lenovo specific EFI boot options, like "diagnostics" and so on, if selected, the UEFI boots into a firmware embedded diagnostic menu. I tried several from the list given via efibootmgr show -v, but there is no shell from which I could access/boot an alternative loader. How I'm supposed to achive the access to this EFI shell? I doubt that on the E540 (beware of the E, it is not a L or T model) does have such a shell. Regards, oh > > > > >> > >>> On 21 Aug 2019, at 20:58, O.
