Dual boot Mint and Zorin on a MacBook Pro

Installing Zorin OS
1

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?

I think the last response you had on the Mint Forum is what you need, but they did not provide a link:

Did You check in the GRUB Config File if the GRUB Menu is active?

4

GNU nano 6.2 /etc/default/grub

If you change this file, run 'update-grub' afterwards to update

/boot/grub/grub.cfg.

For full documentation of the options in this file, see:

info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

Uncomment to enable BadRAM filtering, modify to suit your needs

This works with Linux (no patch required) and with any kernel that obtains

the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)

#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

Uncomment to disable graphical terminal (grub-pc only)

#GRUB_TERMINAL=console

The resolution used on graphical terminal

note that you can use only modes which your graphic card supports via VBE

you can see them in real GRUB with the command `vbeinfo'

#GRUB_GFXMODE=640x480

Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux

#GRUB_DISABLE_LINUX_UUID=true

Uncomment to disable generation of recovery mode menu entries

#GRUB_DISABLE_RECOVERY="true"

Uncomment to get a beep at grub start

#GRUB_INIT_TUNE="480 440 1"
GRUB_DISABLE_OS_PROBER=false

Still no Grub Menu?

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.
