So I'm an intermediate-level Linux user (I've run things like Ubuntu in the past but I'm still learning lots) - recently I got fed up with Windows and decided to install Arch. Having done so, I suddenly realized I wouldn't be able to play any of my Steam games and concluded that I'll need a Windows partition for that.
All the guides I've seen online have recommended installing Windows and THEN Arch, and I'm struggling to understand why that's the case.
I mean, couldn't I just boot into my Arch livecd, use fdsik to resize my Linux partition (which is currently the only one on the disk), create an NTFS partition with what's left, install Windows and then reconfigure GRUB to include the Windows partition in the boot options? Or am I oversimplifying and missing something? I suppose it's possible that Windows will change the MBR somehow and make itself the default boot partition but if that happens I can always just head into a GParted livecd and make my Linux partition the boot, can't I?
