Make pen drive bootable for Windows 7

Microsoft Windows 7 UltimateMany people generally go for WinToFlash for making bootable pendrive of Windows 7 but I would rather prefer the following few steps because using WinToFlash is very simple but not effective. There are some simple steps to make bootable pen drive which can be used for installing windows 7 in future as well. For this you need a pen drive having minimum space of 4 Gb and a Installation DVD of Windows 7(or ISO). Now just follow this steps:-

1. First off all you need to format the USB drive / Pendrive:-

Run the command prompt as an Administrator

Now to find the drive number of your USB Drive, you need to type this and press enter every time.

list disk

Here you can see the disk listed.Note down the disk number of your pendrive for the next step. Generally if we have one hard disk and only one pendrive attached to a system the it comes out to be disk 1. (it can be different). Lets consider disk 1 for this case.

Now type all these words to format the drive:

select disk 1
create partition primary
select partition 1
format fs=NTFS

(wait for few seconds)


Now the disk partition program will exit and you’ll have a formatted USB flash drive ready to be made bootable.

2. Now to make the bootable pendrive, follow this steps:-

Now insert the Windows 7 Installation DVD and to your DVD drive.

Now assume that DVD drive is F and Pendrive as H

Now type F:CD BOOT

Now type this command bootsect /nt60 H: to update your USB drive with bootmgr code.

Finally copy all the contents from the Windows 7 DVD to your Pendrive.

Here you have created the bootable pendrive. 

Now what you need is to make your BIOS to boot from USB. So follow this steps:-

Insert your pendrive to the PC and reboot the system.

Now Enter the Bios system accordingly by pressing the key delete.This is where you’re on your own since every computer is different. Most BIOS’s allow you to hit a key at boot and select a boot option.

Now select the USB/ Pendrive as the first boot driver.

Now save the settings in Bios and restart and you will be able to Install Windows 7 using that pendrive.

3. For those who want to use WinToFlash, then its a very simple procedure.

Download WinToFlash.
Install it.
Select Win PE option for Windows 7
Select appropriate locations.
Wait for few seconds and you are done with it.

Now I'll share my case with you people as I was able to make pendrive bootable Windows 7 in both cases and it was working on my PC, but whenever I tried to install using USB to my target laptop, WinToFlash method didn't work. So I would prefer the firist method
