When I turn on my computer, Fedora (which is the only OS installed on this computer does not boot). Instead, the following is printed to the screen:
System BootOrder. Initializing defaults. Creating boot entry "Boot0120" with label "Fedora" for file "\EFI\fedora\grubx64.efi - Not Found Failed to load Image \EFI\fedora\grubx64.efi: Not found
After what appears a blue window which title is "Shim UEFI key management". It says:
Press any key to perform MOK management
At its bottom, there is a countdown
Booting in x seconds
with x going from 10 to 1.
Fedora versions which are on my computer are the 24, and I believe three other 23, from what I remember.
I don't remember having installed a new software recently.
The first time this problem happened, as I just turned on my computer and didn't look on the screen, I pressed Enter, because normally my computer asks me for the version of Fedora I want to use. If I press the alimentation button, my computer goes off immediately.
How can I make my computer boot to Fedora again?
