In this guide I’m going to walk you through installing 3 or 4 separate operating systems on one PC – ideal for someone who wants to try out all of them on the same hardware or learn an operating system other than Windows. There are five basic steps to making this work:
- Configuring your disk partitions to hold 3 or 4 different operating systems.
- Installing your preferred version(s) of Windows.
- Installing Mac OSX. (Not surprisingly, this is the longest step)
- Installing Linux Ubuntu.
- Configuring the GRUB boot loader to include all OS partitions.
Setting up Your Disk Partitions
This is the first and in my opinion most important step to setting up a multiple-boot system. Unless you are using third-party software, changing partitions can really screw up your system, as certain actions are not allowed in Windows’ Disk Management program (combining empty space to the left of the system partition, etc.). I like to set up the partitions for EVERY operating system before I start. This way there is no creating/splitting/combining partitions later in the process. There are three different disk managers for the three different types of operating system, so things could potentially get out of hand very quickly.
