Making your USB drive bootable for windows 7

i saw couple of post regarding this topic but believe me guys those all tutorials are very hard to follow. i wounder when there is an easy way to do the job then y to go for more harder one... i assume you are a windows XP user and you want to install windows 7, so here is how you do that...


Requirements:
USB Pen Drive (Min 4 GB)
Windows 7.iso

Software needed
MBRwiz Click here to download and Extract it on your hard drive (Diskpart utility for Windows XP doesn’t detect USB drive as Disk hence we need to use this free utility to make bootable USB drive).
Virtual drive (i prefer virtual clone Click here to download its free and easy to use. )

You have these things and you are good to go.

1. connect your USB in your computer. Navigate USB from My computer. right click on USB drive Icon and click format. (if you have any important data in USB, save it first).
2. Mount your windows 7.iso in virtual drive.
3. Goto command prompt(start -->rum <type "cmd"> and press OK ).
4. Now dir to directory where you have extracted MBRWiz and run following commands.

mbrwiz /list (note down disk number of your USB Pen drive)

mbrwiz /disk=X /active=X (X is Disk Number of your USB Drive)

exit

    5. now type these commands

J: (Drive letter of Windows 7 iso mounted with demon tool)

CD boot

bootsect /nt60 Y: (Y is drive latter of your USB drive )

    6. Now copy all files from drive where you have mount Windows 7 iso.
    7.Now reboot your computer and press F9 to get your BIOS screen and select USB drive as your boot   drive.
    8. If every thing goes fine, Your Windows 7 Installation should start from your USB drive.
