Interesting installation of Linux Mint onto external boot NVME media, still boots in about 10 seconds and you would never guess it was running from USB, BIOS limitations can sometimes present problems but there almost always another way.
This is a great way to keep your Windows installation completely separate from the Linux and also you have a portable operating system that can be used on multiple laptops and desktop computers without leaving anything behind on those computers.
It functions and behaves in the same way as a normal installation would, except for the fact you can take the operating system with you on a USB drive or memory stick.
If anyone would like to try something like this then get in touch and get yourself a fully featured portable Linux operating system
