No option to dual boot Zorin

General Help
1

I have a mid-2010 Mac desktop, 1 Tb HD, 12 Gb Ram. Installed Zorin on half the drive, could boot to Mac High Sierra or Zorin. Have some concerns about Zorin, wanted to try Linux Mint. Booted, tried live, decided to install. Installer said could choose between Zorin and Mint. Not so. When I reboot, I can choose between hard drive (Mac OS) and EFI boot which boots Linux Mint. How can I get the option of choosing between Mint and Zorin? I don't care about the Mac OS, will never use.

Thanks for any help.

Was Zorin OS installed as MBR boot?

Hmmm, I really don't know. How can I tell?

Says gpt
If I can safely delete the Mac partition, that would be great. I'll never use it again.

You certainly can do that if you want to.

You may need to boot a LiveUSB of Zorin OS and reinstall Grub.

I'll have to read up on that. :slight_smile:
