I am doing a duel boot Mint and Zorin on a MacBook Pro. I formatted the Mac drive. I partitioned and then installed Mint and Zorin. I cannot get a grub menu. I ran:
sudo apt-add-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install boot-repair -y
boot-repair
With a Mint flash drive and the results were that grub was fixed. Rebooted and still no grub menu. What can I do now?
Long time ago I used rRFInd to boot multiple OSs on my macbook. From doing some reading, it seems that's still the ideal way to go, and the link @swarfendor437 provided (just the home page) has some good instructions on how to use it there.
