How to Create a Bootable windows USB

1) Run command prompt (cmd). This can be done by clicking start and typing typing cmd in Windows 7. In Windows Xp, click on start and then click on run. Type cmd and run. This will open the command prompt which will look like this:
2) Then run diskpart utility from command prompt, by typing ‘diskpart’ on command prompt and pressing enter. This will run the diskpart utility in a separate windows, which is shown in 2nd picture below:
3) Now put in your pendrive in a USB port. Your pen drive must be atleast 4 GB, 8 GB pendrive is best for this purpose. Now go back to the diskpart console and type ‘listdisk’ and press enter. This will list the various storage devices available. You can see the size column of the disk and here we can see that ‘disk 2′ is our pen drive. Warning: In your computer it may be some other number. In our case it is ‘disk 2′.
4) Then you have to type ‘select disk 2′ and press enter. Note: in our case it is disk 2, in your case it may be disk 3, or disk 1 or any other number. You can enter ‘detail disk’ to see the details of the disk after selecting it to verify that you have selected the correct disk. You can see these steps in the image below:
5) Then you have to run a series of commands. The commands to be run in the order are:- clean
- create partition primary
- select partition 1
- active
- format fs=fat32 quick
These steps are shown in the image below:
Please help us in paying our Server maintenance cost by clicking on the ad below.
6) The format step will take some time. You can have a tea or coffee in the meantime and come back. After the format is complete you have to run ‘assign’ command. And after this you can exit diskpart utility by entering the ‘exit’ command. The steps are shown below:
- assign
- exit
- Check out the video below for more


7) After the format is complete, insert Windows 7 Media in your DVD drive, or if you have an .iso image of the DVD, mount that image using any virtual drive software like Power ISO.
- On My Computer, and open the contents of DVD Drive. Press ‘ctrl+a’ to select all contents and copy all the contents by pressing ‘ctrl+c’.
- Now go back to My Computer and open the USB Drive and press ‘ctrl+v’ to paste all the contents of DVD into the USB Disk.
 8) When the copy finishes, you are done just eject the USB Drive and use it to install Windows 7 in your computer/laptop.

Error: A required CD/DVD drive device driver missing, while trying to install Windows 7.



We have already resolved this problem in earlier post but what if you do-not have an ISO/CD-DVD to recreate the bootable USB.

Note: Assuming you already have a windows 7 bootable USB.


Step 1. Download Windows Image tool Click here for the direct download link.

Step 2. Extract and run WindowsImageTool.exe



Step 3: Choose None at Source Path, connect your Bootable USB disc to the desktop/Laptop and select it at Destination path.


Step 4: Press Start and you are ready to install :)


In some motherboards USB drivers wont work even after installation of windows use DVD drives to install the drivers or in-case you do not have a CD/DVD drive drop us your e-mail ID at comments below.
