SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Create a bootable USB drive 2. Tick "bootable" and "bios-grub" 3. save 4. unselect "bios-grub" 5. save 6. boot into it OBSERVED RESULT I had this on a failed Tails install, which only worked through Rufus. Additionally not not booting, it kept booting into grub, although I had disabled it twice and saved in between. EXPECTED RESULT Normal select / deselect behavior. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu (available in About System) KDE Plasma Version: 5.22.5 KDE Frameworks Version: 5.86.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION BIOS, old well supported Hardware, no Problems booting into Linux
Can you please explain a bit more what you were doing. I don't think partition manager has capability of creating bootable USB drives. Did you create USB drive with some other program and then edited partition flags with partitionmanager?
