Installing dual operating system on the same hard disk

Sometimes we need to install dual operating system in our computer. For example: you are very familiar with one of the earlier versions of windows operating system but you want to try the new version. In this situation you may install and use the newer release of windows operating system on the same computer alongside the older version.

On the other hand, we may also install and use both of windows and Linux (including Ubuntu, Kubuntu etc.) operating system at a time on the same computer, in the same hard disk drive.

Installing both windows and Linux operating system on the same hard disk drive is not so hard. Even it will work very smoothly and successfully without any disturbance. Let's see how to install dual operating system on the same hard disk.

 Step 01  Select two different drive/partition for two OS
First of all you need to select two different drives (also known as partition) of your hard disk drive. But in some computers there is only one disk drive with a single partition. If you have such a computer then you need to re-partition the hard disk drive.

However, suppose there are three drive/partition in your hard disk and you want to install an earlier version and a newer version of windows operating system. In this case you have to select Local Disk (C:) for the earlier version and the last partition for the newer version of windows operating system.

 Step 02  Install the earlier version in Local Disk (C:)
Simply install the selected earlier version of windows operating system in the first partition/drive known as Local Disk (C:).

N.B. If you want to install a windows operating system and Linux/Ubuntu together, then you have to also install the windows operating system first in the Local Disk (C:) and later the next one in the last partition of the hard disk drive.

 Step 03  Install the newer version of windows OS
After installing the earlier version, now you need to install the newer version of windows OS or any other OS like Linux, Ubuntu, Kubuntu etc. in the last drive/partition of the hard disk. Now restart your computer, you will get an option to select the operating system by which one you want to boot your computer.

Boot your computer with one of the installed operating system and enjoy your dual booting computer. Learn to make a pen drive bootable and install an operating system using it.
