One could perfectly state this sentence otherwise, unskilled people install popular OSes all the time. Apart from that, this topic was created by a person who didn't seem to be a beginner at setting up an operational system, but Mint and Ubuntu do offer full instructions "for dummies" to set them up, specially alongside windows. Sticking the discussion to this topic... Unfortunately, a lot of multimedia drivers for home use are feature richer and often stabler in windows (Linux resounds much cleaner due to its low level hardware output capabilities though). Many proprietary video drivers are actually present in windows by default (MS-rebranded) and fully hardware-rendering capable, which doesn't happen with FOSS. Installing/updating drivers from its official proprietary releases (companies' websites/sources) is easier in Windows. A Windows setup may take over the MBR, but popular Linux distros installations respect and will only wreck it when the user is not careful enough. It's pretty basic to understand which may be installed first for multi-boot purposes; the topic owner knew it. The problems he experienced were solely his fault, I hope he figured that out. However he probably wasn't too familiar with *nix partition tables, he have used a Mac OS, and despite the apparently misleading MS-DOS references, he made sure on which storage devices and partitions his OSes and boot loaders were installed, guided by storage sizes. It was not hard to realize what he implied. Agreed. Also, as constantly mentioned, he could have placed grub in the MBR of the HDD in which only Mint was installed in order to boot it with bios shortcut keys - not ideal for most users, but it seems he would mainly run Linux for the sake of a single game. His disk array is rather simple. Ubuntu based distros installations are smart, they can take care of it. The main problem, here, is that he must acknowledge there were no software flaws.
