Content preview:  I am currently running Mint and Ubuntu along side of Windows10
   using Grub2. Â I want to replace Ubuntu with Zorin. Â I've searched for info
   on how to do this, but everything I find deals with installations including
   only one Linux system and Windows. Â Any help would be greatly appreciated.
