I've finally installed Manjaro on my second machine. However, because it's main purpose is for gaming, this os is currently not capable of running certain games (dayz, arma 3, star citizen, etc). I have tried running Arma 3 through a Windows Vbox VM, but the performance was terrible. I have heard of KVM, however I'm not how much time I want to sink into learning, installing, and troubleshooting that process (unless someone has a quick and easy solution for the switch). So, I've decided my next best option is to just install windows on another drive to play certain games. In my past experience, windows ruin the grub boot process, and so requires a fix up after installation. Does anyone know how this works? I've read here that it's as simple as typing a command into windows after installation. However that guide is for Windows -> Windows + Linux. I'm not how it would translate, going from Linux to Linux + Windows.
Anyone have any advice?
