If you try to install Trisquel 7.0 1)Trisquel Operating System website: https://trisquel.info/en on a MacBook Pro using Virtual Box 2)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.
This is due to Trisquel kernel requiring PAE 3)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
This option “Extended features: Enable PAE/NX” must be enabled. Restart the VM and you can continue installing Trisquel GNU/Linux.
