Most computer having only one operating system but in this tutorial you can understand that how you can have multiple operating systems and choosing between them at boot time — is known as “dual-booting.”
You can install Windows 8 with Windows 7, have both Linux and Windows on the same computer, or install Windows or Linux.
Step 1: Make a backup
Firstly make sure that you have backup of your all data. So just create backup and store at other hard drive or external hard disk.
Step 2: Create a partition for Windows 8 installation under Windows 7
As you can see in disk management, I have a 160 GB hard disk that is configured with a 64 GB in (C:) partition on which Windows 7 is installed and other two data partitions which are blank. Now what is need to do now for installing windows 8?
Step 3: Install Windows 8
- Make a bootable Pen drive or CD of windows 8.
- Just plug in pen drive or insert CD on your system and restart it, then a screen comes down of booting then press any key to continue.
- Windows starts to install automatically. When you’re choosing installation type, be sure to select Custom (advanced).
- And now be careful here. Choosing the wrong partition and you will loss or wipe your data. Installation altogether, so make sure you pick the new partition created for Windows 8 installation in the first step. Choose it to continue.
When you are done your computer automatically reboot. And in system booting time it asks you that choose an operating system.
