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: This is the first and in my opinion most important step to setting up a multiple-boot system.
Try not to take up all the shrink space, but give a healthy space to your other operating systems well. I shrank my partition by 20000 MB (20 GB) to give some space to OSX and Ubuntu.
From here you can add, delete, format, extend, and shrink partitions.
If you have one instance of Windows taking up your entire hard drive, you will see a screen similar to mine.
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.
