My Lenovo Idepad S205 seems to be in a worse situation than in the question here.
Unfortunately the answer given there does not solve the problem.
The laptop just boot cycles. It will boot my USB stick to a live copy of Ubuntu and I've run boot-repair but with no luck.
boot-repair output here
I've managed to get the message that flashes up on boot and it is as follows.
Could not open "\EFI\BOOT\fallback.efi": 14 Failed to open \EFI\BOOT\grubx64.efi - 800000000000000E Failed to load image Failed to open \EFI\BOOT\MokManager.efi - 800000000000000E Failed to load image
