Definitely prefer the BootLoader in YaST for a new user. The Boot loader seems to be somewhat stuborn if you edit /boot/grub/menu.lst yourself in 11.2, I have had phantom extra entries appearing as a result.
The expert should unddoubtely turn Perl Bootloader off, and just have a “Latest” entry, and a known good fallback kernel, which won’t get updated.
Others should best, edit the sections and adjust so you just have one called “Windows”, I found it offered to boot things like Restore partitions which would try to wind back Win’s C: to it’s OEM pristine condition.
