How to Install Windows 7 from USB easily

There are few methods to do this, most of them involve running disk part commands and partitioning USB drive etc. which I think it makes harder for technically challenged people. Using this method it makes it very simple and can get the things done easily.

We are going to use Windows 7 USB/DVD download tool to create Windows 7 bootable USB stick.

Install Windows 7 from USB

Step 1:

Download Windows 7 USB/DVD Download Tool for free from Microsoft.

Step 2:

Install the Windows 7 USB/DVD download tool on your system.

Step 3:

Go to Start > All Programs > Windows 7 USB DVD Download Tool and open the application.

Step 4:

Now you need to click on browse and select the Windows 7 ISO Image and click next.

Step 5:

You’ll get two options to choose either USB or DVD, In this case you could select USB.

Step 6:

Once you select USB click on Begin copying.


Step 7:

Once it begin first it will format your USB drive and copy the installation files to it.

You’ll see the above screen once it’s complete. Then when you plug in your USB should be seeing  this screen.

If this method fails then you could try the following manual creation method.

Step 1:

Open the command prompt (If its Windows 7/Vista open it as administrator) and type in Diskpart


Note: If it fails to find diskpart then you could download it from Microsoft.

Step 2:

Then type in list disk


In this case my USB device is Disk 4

Step 3:

Now type in Select disk 4

Step 4:

Now we have to clean the drive so type in the command clean and press Enter.

Step 5:

Now we have to set the USB as primary partition so type create partition primary.

Step 6:

Now type in active to make the partition active

Step 7:

Now to we need to convert the USB partition as FAT32 so we have to run the command

format fs=fat32 quick

Step 8:

In order to enter drive letter type in assign

Step 9:

Now you can start copying the Windows 7 installation files to the USB. Once that’s complete your Windows 7 USB Installation drive is ready.

  1. LOL – I was just in the process of making a short post on covering WintoFlash and will schedule it soon 🙂

    Doesn’t DiskPart have to be from Vista or Windows 7 in order to work on the USB Flash Drive?

  3. Yes but if you look the Note under step 1 I have mentioned the link to download it from Microsoft. If you can’t find it I’ll re-post it here

    What space do i need on the USB thumb drive?

  5. I would recommend 4GB and above.

  6. redk9258

    The DiskPart linked above is 10 years old. I don’t think it will work on flash drives.

    Hi all here,

    It’s very interesting the info here and i would like to try to create
    a bootable usb flash stick to install Win 7 in my laptop which hasn’t attached a DVD drive, but there are two problems:

    1. The download link provided here (step 1) for the “Win 7 USB/DVD download tool” is dead. No one didn’t noticed that??!

    2. DiskPart in Win XP i tried, can not “see” usb flash sticks..

    Now what..?


  8. The link is working. Please re-check.
    Anyway here is its direct download link from Microsoft:

    Hi again,

    I’m sorry but the link is dead.. This is the same link which posted in thread
    referred in step 1 on this thread. So, where did you get this tool to make
    this comprehensive tutorial with screenshoots??

    Also, what about DiskPart? As i already mentioned, i tried this tool in
    Win XP, but it can’t see usb flash memory sticks..

    Windows 7 USB/DVD Download Tool –
    Or use 7-zip to extract it from the Windows 7 ISO file…
    This would have to be a 32-bit ISO if your current OS is 32-bit.

    BTW, this tool can ‘burn’ other bootable ISO files too. The trick is that the ISO must be in UDF format, not ISO9660 or Joliet. You can easily build a UDF ISO using the excellent ImgBurn. If you have an ISO file that is ISO9660, use 7-Zip to extract it and ImgBurn to build a UDF ISO file.

  12. Hello George,

    See if this link works and if you have AV Tool bar disable it or try with a different browser.

    Wintoflash is a better option. It creates the bootable install USB directly from the original DVD media. Why worry with ISO images when you dont have to?

    This article does not discuss paying for WIN 7. Is it a free download?

  15. i am using windows xp i cant view my pendrive in list disk it shows only my hard disk what is the problme

    I downloaded and install windows 10 creator update, But I dont like it. After installation Microsoft shows downgrade option early after upgrading to Windows 10 and remove it after one month. I recently upgrade my windows 8.1 Professional operating system to windows 10 Professional being getting a license from ODosta Store
    But I did not like its overall structure. I think Its not Windows 10, Its version should be windows 6 as it has many faults.
    I tried to downgrade back to my existing win 8.1 os and I saw as Microsoft was giving me option to downgrade. I thought that I’ll downgrade after two month But after two month when I tried again, Microsoft removed that option. Now what to do. I searched and found your post, Which is very helpful for me. Thanks for sharing these details here.
