Last week my new netbook crashed. I felt a problem is the how to install Windows 7 through a USB. At last i found a solution.
To create a bootable pen drive with Windows 7 you need a ISO file of Windows 7 and a pendrive with atleast 4 GB size .
Below are the steps to create a bootable USB using the Microsoft tool :
System Requirements:
Windows XP SP2, Windows Vista, or Windows 7 (32-bit or 64-bit)
Pentium 233-megahertz (MHz) processor or faster (300 MHz is recommended)
50MB of free space on your hard drive
DVD-R drive or 4GB removable USB flash drive
