How to install Windows 7 from a .iso without burning onto a DVD

Windows 7 doesnot allow you to install off the same Hard Disk. But if you didn't want to burn the .iso image of Windows 7 that you downloaded to a new DVD - you can still install it off the .iso file by using the method below.

You will need a portable hard disk / pen drive though.

Incase, you have a portable hard disk or a pen drive - do the following :
1. Get WinRar ( and install the software on your machine. WinRar is similar to winzip but supports many other formats including .iso.
2. Extract the .iso of Win7 to your pen drive / portable hard disk. Place the extracted files into the root of the drive - your other data can be put into folders.
3. Restart your laptop and hold F9 / F2 to enter into boot-menu which gives you a choice to load from. Here select your pen-drive / portable hard disk - usually a USB device.

Done - that's all it takes. You can now go ahead with the normal install process.
