http://bugzilla.suse.com/show_bug.cgi?id=1157670 http://bugzilla.suse.com/show_bug.cgi?id=1157670#c22 --- Comment #22 from Stefan Hundhammer --- I learned just recently that our yast-bootloader module indeed reads the /boot/grub2/grub.cfg file. That file is generated; some parts are generated by the /usr/bin/os-prober command. If that os-prober finds some other OS on the disk that has such an invalid UTF-8 sequence in its name, it might write that name to the /boot/grub2/grub.cfg file (as name for the corresponding item in the boot menu). That might be plausible if that other system dates back to the pre-UTF-8 era. Please try invoking that command manually: sudo os-prober Does that output contain weird characters? Is that output corrupted or cut off? If that output contains any more than the one entry for openSUSE / Leap, please redirect it to a file and attach that file here. sudo os-prober >/tmp/os-prober.txt (attach /tmp/os-probert.txt to this bug) -- You are receiving this mail because: You are on the CC list for the bug.
