Hi,
I have been an openSUSE user for quite sometime and use this as my primary distro. I currently have my laptop dual booted with openSUSE and Debian. The one issue I am facing is that openSUSE does not show Debian in the grub menu. Debian is on sda6. These are the commands I ran -
grub2-mkconfig -o /boot/grub2/grub2.cfg
grub2-install /dev/sda
I was able to successfully dual boot Xubuntu and Rosa with openSUSE recently. Appreciate your help. Thanks!
