Installing an operating system through a bootable USB pen drive is much better then DVD.
But, to use the usb pen drive to install an OS, it should be bootable; or you'll get some error like "missing operating system". Its because, some systems wont support the usb pen drives to boot, which are formatted in filesystems such as FAT32.
These pen drives should be formatted in NTFS filesystem, in order to make it bootable.
This process can be done by using the command prompt in windows 7 or windows 8, So you don't need any program or software to make a pen drive bootable.
Now bootable USB pen drive is ready to use.Now you can copy and paste windows 7 or windows 8 in your pen drive. It is easiest way to install windows 7 or 8 in your system.
When you want to install windows, plug-in bootable pen drive and restart the system and press boot function key as per different system (f1——-f12).
Before making bootable USB pen drive please make sure that you are using only one Pen drive at this time. This process is only for windows 7 or 8 not for Xp.
