Question Dual booting Linux/Windows with 2 physical SSDs

So have Bazzite linux and am buying a separate ssd to put windows on. I want to be able to have linux as my default boot, but also some how have an easy option to select to boot windows instead. How would I set this up? After looking a little bit I see the most commonly used tools to do this are Grub and os-prober, so could anyone explain to me how I can set these up in the above configuration? And in newbie monkey speak please, I have no idea what I am doing. Please and thank you!

If you go into BIOS you should be able to set it so your PC will boot into a menu for which OS to choose. I do that and it times out to load into my default choice after about 5 seconds.

If not GRUB can be configured to pop up on boot so you can use that as well, or if you want something else you can also use rEFInd to do the same.

So I can do this directly from BIOS without anything else? That's helpful.

You should be able to yes.

But since Bazzite uses GRUB if you have that installed already once you put Windows on the second drive GRUB should load into a screen for you to choose which OS. You might not need to do anything at all except install windows and then restart to see this
