After lots of request from our reader and followers now I am going post the best and very simple method to install Windows7 via USB drive.

So, today I am going to post a article about installing windows 7 via USB drive, this because in-case if you got a net-book which doesn’t have the DVD drive or your DVD drive is faulty then you came to the right place. You can also use these step to create boot-able USB Disk for Windows repair disks/any windows Vista also. Ok, enough talks, lets get started.

So, at very firstly what you’ll need is as follows:
  • A Windows 7 DVD/Physical Disk or an ISO file of your copy of windows or the ISO or an IMAGE-file of what you want to make it boot-able..
  • USB Drive (4GB or higher depending on your Windows version.(You can even use external HDD also)(If you are creating repair disk than you can use 1GB is enough).
  • A working system(recommended Windows-7) to prepare the USB drive.

STEPS:

PART-1

1.) Plug in your USB drive to your computer.
2.) Open Command Prompt under administrator right. Start>All Programs>Accessories>Command Promt.
Run as administrator

open an elevated command prompt

Right Click On Command Prompt and choose Run as Administrator(In case of windows 7). ( other users just run it under a administrator type account)

3.) In the command prompt, type ” diskpart ” and press Enter.

4) Then type “LIST DISK” press ENTER(It will list all the HardDisk drives and removable drives).
5) Now type  “SELECT DISK 3”  (In my case I have selected 3 as my selection but it depends upon you, what you want to select
(e.g.Check for the size that is similar to your USB drive, in my case it is a 8GB pen drive)
6) After you have selected the disk, then type  ” CLEAN ” press ENTER. ( It basically clean your previous partition table for the USB drive)
7)Now type ” CREATE PARTITION PRIMARY ” and press ENTER. (It will create a primary partition on the USB drive).
8)Now type ” SELECT PARTITION 1 ” (It will select the partition that you have just created).
9)Now type ” ACTIVE ” . (It will mark the partition as Active).
10)Now type ” FORMAT FS=NTFS QUICK “.(It will format your USB drive with ntfs file system).
11.) Now type ” ASSIGN “.
12. Now type ” EXIT “.

PART-2:

1.) Now, insert your WIN-7  DVD to your drive or Mount your ISO to the Virtual drive and remember the letter.(In my case it is H).
and also remember the USB drives drive letter also.(In my case it is J)
2.) Now, again start (an elevated command prompt) cmd as you did in previous step.
3.) Now, type “ h: “.(It will change your drive to H:).
4.) Now type “ cd boot “. (It will change your drive to boot folder).
5.) Now type ” BOOTSECT.EXE /NT60 J: “.(It will update your USB drives MBR to bootable).(Here J: is my USB drive).

So, Now copy all the contents(or all files of the Win7 iso) from the DVD drive to your USB.

whoaa!!!. That’s it your USB drive is now bootable.

Now, Start your computer and change the boot order of the first boot drive as USB drive or
also you can temporarily select the boot device by using the start-up key of your BIOS.

e.g:  F2, F11, F12, Esc, F8, Del etc.(Press any one of this on the BIOS screen)
