Hey,
I got a Problem and need help as I am new to Linux. (and no IT professionial). I try to describe it shortly and would be very thankful for some help!
- Problem: I Installed the recent Fedora KDE Plasma in a Dual Boot with Windows 11. It worked perfectly fine for one day. When I start my Laptop now it boots directly into windows and I can not choose Linux anymore. It seems to me that some entries are missing but I do not understand what exactly is wrong.
- Goal: I want to restore the boot menu so I can choose between Fedora and Windows at startup.
- Things I tried: I tried to run Boot-Repair with an Ubuntu Live Image. It suggested no automatic repair. As I do not really understand what the exact problem is, I did not want to mess with the terminal in order to not break things even more. (I looked into documentation and quite a few videos on the topic, but did not manage to finde one, which seems to match my exact situation.) Secure Boot is disabled at the moment.
- What happend before the problem: Nothing? Just at one point when I switched my Laptop on again a blue screen with some options showed. I was irritated so I switched it of again and afterwards the dual boot options were gone. I did not update any of the two OS prior.
Thanks in advance for any help!
This ist the output of the Boot-Repair Programm:
