Dual booting Niresh Mavericks with Mojave?

Don't see how you could brick your system if you're installing Maverick on a separate partition. They both will be using the same EFI folder to boot from. If for whatever reason Mavericks won't boot, Mojave will continue booting unless you make changes to the EFI Partition to accommodate Mavericks.

I never used Niresh's stuff but it should be the same as any installer. So instead of booting with Niresh's boot loader, boot with your Mojave loader, when you get to the Clover GUI, select to boot Mavericks. Continue with the installation if you could get that far.

Distros are best avoided. This being said, if Niresh Mavericks is booting with Chameleon -and I believe it does by default-, you won't be able to boot Mojave which requires Clover at this point of time (or Enoch if you know how to set it up). But you cannot possibly "brick" your E7240, no. At worst, you'll break your boot loader, that's it.

 

You'd be better off by:

  1. taking a backup/clone of your Mavericks current installation
  2. installing Mojave on a 2nd partition
  3. install clover in the EFI

 

Normally, Clover should be able to boot Mavericks but since there are significant changes between the 2 x OS and their respective ACPI patching/Clover setup, you may encounter trouble. Question is: why do you want to keep running Mavericks 10.9. It's 5 years behind and obsolete these days.

 

If you're adamant on keeping Mavericks, you could always use your Mojave USB installer to boot Mojave on a 2nd partition of your disk.
