And that is one of the reasons Linux isn’t at a higher market share. Linux is actually incredibly easy to install. Even back in 2008 or so, it was easier to install than windows. The live CD would give you a full OS with an install button. If you could install windows 7 you could install Linux.
Asking a user to then install something like virtual box and understand virtual hardware and disk images is a step up from that. Not to mention the clunkiness of it all.
