(Caveat: I am still on Mint 17.3 -- haven't bothered to upgrade to 18 yet)
Literally the only things where I need to use Windows are:
When I'm in the mood for games, I run Steam (which is perfectly supported in Linux, so no need to mess with Windows there).
For the Windows software needs, what I do is run a virtual machine using Oracle VirtualBox. I dedicate 4 GB of RAM and 3 computer cores to the virtual machine and that seems to be plenty. Since I have 16 GB of RAM and a 6 core processor, I can basically run both simultaneously. And both do perfectly OK.
mark- i have steam on my windows boot os- how do i get it on linux? Do i need a special version of linix? I’d like to play my games on linux (dues ex- F.E.A.R- etc not too taxing older games) if possible- be much easier rather than dual booting- and i can finally almost get rid of windows altogether (expect for photoshop- need to run photoshop for photography- doesn’t run well in VM or wine-)
