Hi, a few days ago during patchday I received an firmware update. No obvious changes, bootloader still worked, but now as I wanted to restore my linux partition from a backup I can not boot it any more. Spent a few hours, even blanked the whole SSD and installed linux from scratch, but the bootloader does not work any more. Of course secure boot is turned off. The installation runs through, grub, everything looks normal, but it does not boot. When I restore the whole SSD to its previous state with EFI, Win8 and Debian partition it immediately boots into Win, no grub bootloader any more. Are the previous firmware files somewhere available, to try a downgrade? Can anyone confirm my observations? I guess a workaround seems possible, with a Micro SD carrying some minimalistic linux to boot into the partition, but this is a major drawback, and I do not know enough about Linux to get this running - so I have carry two PCs into my holiday :-( With best regards Ralph.
