Installing Trisquel GNU/Linux on a MacBook Pro

If you try to install Trisquel 7.0 ((Trisquel Operating System website: https://trisquel.info/en)) on a MacBook Pro using Virtual Box ((Virtual Box website: https://www.virtualbox.org/)), you’ll run into a problem.

When you configure the VM, and go to start it, you’ll get the following error:

This kernel requires the following features not present on the CPU: pae.
Unable to boot – please use a kernel appropriate for your CPU.

Error with Trisquel on a VirtualBox VM

This is due to Trisquel kernel requiring PAE ((Physical Address Extension wikipedia article: https://en.wikipedia.org/wiki/Physical_Address_Extension)), to be enabled.

The solution is to enable it in settings –

Settings->System->Processor

Trisquel running on Virtual Box VM - System VirtualBox Manager

This option “Extended features: Enable PAE/NX” must be enabled. Restart the VM and you can continue installing Trisquel GNU/Linux.
