I have Laptop Gigabyte G5 KF with two operating systems Windows 11 and ubuntu.
After selecting the system in GRUB, the system boots but immediately freezes.
The problem started after I started Ubuntu 24.04 LTS from a bootable USB.
I tried to boot another system from a bootable USB but with the same result.
I reset the BIOS settings but that didn’t help either.
I thought about reinstalling the system but it probably won’t help and I’m not able to do it.
