How To Install Two Windows Operating Systems In Single PC

This tutorial shows, how to install Windows 7 or 8 with Windows XP. To follow this tutorial, you should have enough free space on your HDD and at least two local disk drives already created on your HDD. In case you don’t have, you can also create them while installing Windows 7 or 8.

Remember! You can only install newer operating system with older operating system already installed. For example- you can install Windows Vista, 7, 8 or 10 on Windows XP but you can’t install Windows XP on Windows Vista, 7, 8 or 10. If you install older version of Windows over newer version, only newly installed Windows (older version) will work and you will lose your currently installed newer version of Windows.
