I have a machine from the company I am working in. I don't have the permission to change anything on it. It's on Windows and it sucks.
I am thinking of installing Ubuntu 20.04 LTS on a brand new external SDD. I want to be able to boot from this SSD if it's plugged in and from windows if not.
What could go wrong? If the Windows OS is damaged, I may be fired !
An help? I would appreciate a link on how to do it the most safer way. There is tons of tutorials with different approaches. I am lost.
PS: the machine is Dell 3351 and the OS is windows 10 PRO.
