I'm curious: why not run one or the other in a VM? Looking at Mike's resume, the technologies he is working with (LAMP stack, Ruby, PHP) seem like they would run perfectly fine in a VM.

I've been doing embedded development (with a Linux based toolchain) on a Windows 10 host with Ubuntu in a VM, and it seems to be plenty nice on modern hardware (and a lot of RAM). And I don't have to make a choice to boot back and forth: Two systems for the price of 1.5. :)

Edit: My question aside, I fully appreciate the article's primary goal, which is to document the nonobvious hoops the author had to jump through to get dual boot to work. Thanks!
