How to install linux on a lenovo 720s-13arr (amd ryzen 5) laptop?

Yes sure I'll be glad to tell you but first I'm going to assume you're running Windows 10 you need to go to the control panel first and then find power options find what the power button does click on that find where it says show settings that are currently unavailable then uncheck fast start click apply.

Now in BIOS verify that secure boot is turned off at Legacy is enabled in search your installation media F12 to your boot menu then go ahead and let Linux load up from the stick after you have verified that everything is working click install you can either let Linux use your entire disk which will wipe out windows 10 or you can choose to make a partition and install it along side of windows good luck if you have any further questions just ask me

Get Linux. Install.
Search Google how to.
