After install, simply plug back the first drive and you are done.
Power of your PC and unplug your first drive and then plug in the second drive and install a second OS on that drive. If you are adding the second drive to your PC for the second OS, you can simply do the next thing. In these two places firmware will find the location of your installed OS and then give control to your OS.īut then how are we dual booting and as always there are a couple of ways (freedom :)). This is a bit too technical but don’t worry you only need to know that there is info where your OS is stored, and PC but need to have this info in order to boot your PC. Now, the firmware searches somewhere to find the entry point for your OS and that information can be found in Master Boot Record MBR for Legacy Boot or in GUID Partition Table (GPT) for UEFI boot. To get more detailed with this we need to know a bit about the boot process, and how does our PC know to start our OS.Īt the beginning PC doesn’t know anything about its hard drives, and the first thing is to perform something that is called Power On Self-Test or POST. Basically If you can install an OS on your machine, you can dual boot it with Another OS that can run on your machine. It can be Windows and Linux, Linux and Linux, Windows and Mac in some cases, and so on. When we say dual boot we are saying that on our PC and/or laptop there are two Operating Systems installed. So, what is Dual boot Pop OS? What is good to know before we start.
