I have a 2019 Predator Helios 300. It came with two M2 SSD slots. One is already with Windows 10 installed, which is my main OS. But I'd like to buy an extra SSD to put in the remaining slot and install Linux Mint in it.
But this is the first time I'm doing such a thing, so I'd like some guidance. I know I'll need the Linux Mint image (duh), which is obtained from their official site. But afterwards, how do I go through the procedure of having two OS's at the same time? I'd like making possible to alternate between the two when I turn on the laptop or something.
A step by step guide would be very helpful.
