I want to install Linux on a portable external USB SSD. The scenarioįirst of all, let’s summarize what I want to do. In the end, we’ll get a UEFI bootable device, but without being scared of breaking the UEFI boot loader of your computer, since we’ll do that using a virtual machine.

Remember that the idea is to have a USB drive that will work as a portable Linux operating system on any computer. That’s the third post on installing Linux on a USB drive!
