simple steps to Install Windows 7 or Windows 8 without creating any bootable pen drive or bootable dvd

Hello today i am going to tell you that how to install window 7 or window 8 without creating any bootable pen drive or bootable dvd. If u have .iso i.e. image file of windows 7 or/and windows 8 and uwant to install windows 7/8 in dualboot configuration this simple and useful trick can save u lot of time which u would otherwise be wasting in first creating bootable media (pen drive or dvd). what u need is a any freeware iso mounting software or iso extractionsoftware like *. Daemon Tools Lite *. Alcohol 120% *. win rar *. virtual clone drive i prefer virtual clone just ~1.5mb in size installs under a minute. Follow these steps:- *. Simply mount or extract the contents of iso. *. Then u look for sources folder and under sources folder there will be an file named setup.exe *. Just open that by double clicking and installtion starts like normal boot . only drawback of this method is that u can not format the c: drive or other drive in which your currentoperating system is installed. if u want to upgrade install , it is then again as normal installtion. enjoy...
