Now that you have a bootable copy of each OS on DVDs or USBs (as explained in part 1) here are the rest of the steps to use Windows and Linux on a single computer.
Installing the two OS
Now the next step is installing Windows and Linux on your computer. For Windows, you are going to need a product key unless your computer came with Windows already installed. In such a case the key would be embedded into your computer. But if you bought the retail version of Windows during the installation process you are going to need that key for proceeding forward. For Linux, since in most cases it is free, you don’t require such. Just follow the instructions of the installer to advance. You would find installing Windows a lot easier and less time taking. While for the Linux distribution it is highly likely that you would need to invest your time, energy and mind.
It is better to install Windows first
If you want to make this process less hectic install Windows first on your PC. Why? Because during the installation process many Linux distributions, such as Ubuntu, give you the option to install it while keeping Windows. If you select this option, the installer will handle this. It will analyze the Windows and partition your hard disk without causing any trouble. However, Windows provides you with no such option. Hence you would have to partition your hard disk if you want both the OS on a single hard disk and you might mess up.
You’ll have to allocate space to each OS. This allocation would depend on your needs. You would definitely want Linux to have more memory than Windows if you wish to use it more often and vice versa.
Switching between the OS
To switch all you have to do is restart your system. You will be asked to select the OS you want to access when the computer is booting and that is it.
