So the Solution is Below..

Method 1.

Requirements to create bootable Windows USB:

# Windows 7 or Vista ISO

# Pen drive with 4GB+ (2 GB is sufficient for XP)

# 15 Minutes of free time

Procedure:

1. Insert your USB flash/pen drive to your system and backup all the data from the USB as your USB drive will be formatted during the process.

2. Now download WinToFlash tool (free) from here.

3. Run the tool, and browse to your Windows 7, Vista, or XP DVD files (make sure that your USB drive letter is correct).

"WinToFlash starts a wizard that will help pull over the contents of a windows installation CD or DVD and prep the USB drive to become a bootable replacement for the optical drive. It can also do this with your LiveCD.

You don't have to worry about scratches on the disc or misplacing your original media discs once you transfer their contents to the flash drive. The optical drive is quickly becoming a thing of the past, especially in office environments, as media is shifted to the cloud."

4. Click Create button to begin the bootable USB process. Wait for few minutes to see the bootable USB.

5. That’s all!

Method 2: Manually
Create Your Pendrive Bootable
bootable USB guide, here we assume that you are using either Vista or Windows 7 to create a bootable USB.
1. Insert your USB (4GB+ preferable) stick to the system and backup all the data from the USB as we are going to format the USB to make it as bootable. 

2. Open elevated Command Prompt. To do this, type in CMD in Start menu search field and hit Ctrl + Shift + Enter. Alternatively, navigate to Start > All programs >Accessories > right click on Command Prompt and select run as administrator. 

3. When the Command Prompt opens, enter the following command:
DISKPART and hit enter.
LIST DISK and hit enter. 

Once you enter the LIST DISK command, it will show the disk number of your USB drive. In the below image my USB drive disk no is Disk 1. 

4. In this step you need to enter all the below commands one by one and hit enter. As these commands are self explanatory, you can easily guess what these commands do. 

SELECT DISK 1 (Replace DISK 1 with your disk number)
CLEAN
CREATE PARTITION PRIMARY
SELECT PARTITION 1
ACTIVE
FORMAT FS=NTFS
(Format process may take few seconds)
ASSIGN
EXIT 

Don’t close the command prompt as we need to execute one more command at the next step. Just minimize it. 

5. Insert your Windows DVD in the optical drive and note down the drive letter of the optical drive and USB media. Here I use “D” as my optical (DVD) drive letter and “G” as my USB drive letter. 

6. Go back to command prompt and execute the following commands:
6.1. Change directory to the DVD’s boot directory where bootsect lives:
d:
cd d:\boot

6.2. Use bootsect to set the USB as a bootable NTFS drive prepared for a Vista/7 image. I’m assuming that your USB flash drive has been labeled disk G:\ by the computer:
bootsect /nt60 g: 

(Where “G” is your USB drive letter) 

7. Copy Windows DVD contents to USB. 

You are done with your bootable USB. You can now use this bootable USB as bootable DVD on any computer that comes with USB boot feature (most of the current motherboards support this feature).
