I am new to Endeavor and new to bspwm. I just installed Endeavor. When I reboot my grub menu only shows endeavor (sda1) and not my Opensuse installation (sda2).
What do I need to do to fix this and why did this happen?
Thanks!!
Hi! Welcome to the forum! 
Is your issue because grub is not running os prober? 
You may try this:
sudo nano /etc/default/grub
Go to the end of the file, and type this in a new line:
GRUB_DISABLE_OS_PROBER=false
Ctrl + s to save
Ctrl + x to exit
Now update Grub configuration:
sudo grub-mkconfig -o /boot/grub/grub.cfg
It may take some time because os-prober is slow. Be patient!
