How to Create Bootable Windows 8 USB Drive from ISO Image

Ads by Google

We saw yesterday how you can install and test the latest Windows 8 build on your system as a virtual operating system using Oracle VirtualBox. For those who haven’t heard, the consumer preview of Windows 8 is now available for everyone to test. It’s like what Microsoft did during Windows 7 launch. They first released a preview build for free to get feedback from the users before shipping the final version of the product. And the big news that the Windows 8 consumer preview has already crossed 1 million downloads.

UPDATE: You would be happy to know that we recently compared the Top 5 Tools to Create Bootable ISO in Windows. Do check that out to know more about better tools to get this job done.

After few hours of testing I was convinced that the build is stable enough, and I can take it to next level by installing it parallel to Windows 7 via dual boot. If you too are looking forward to install Windows 8 on your computer, I would prefer you create a bootable USB drive instead of a bootable DVD.

Note: This is a consumer preview of Windows 8 and not the final stable version. So keep in mind that you are always on your own if you mess up your computer while installing or using this Windows 8 build.

A USB drive is always faster than DVDs and the chances of failed or corrupt installation are very low as compared to optical media. So lets see how you can create the bootable USB of Windows 8 in the easiest way possible.

Necessary Prerequisites

  • Download the ISO file of Windows 8 on your system.
  • A minimum of 4 GB removable drive for 32-bit Windows and 8 GB for 64-bit Windows 8 operating system.
  • Backup all the data (if any) from your removable drive. Better, backup important data on your PC too.

Creating the Windows 8 Bootable USB Drive

Step 1: Download and extract WinUSB Maker on your computer. WinUSB maker is a portable application and thus does not require installation of any kind. You only need to run the .exe file.

Step 2: Run the WinUSB Maker tool with administrative privileges to start creating your bootable USB drive. (right-click on the file, and click Run as Administrator)

Step 3: In the tool, select the option ISO image bootable disk under the Functions  section. Select Normal Detection Mode and browse for the Windows 8 bootable ISO (Image file) you have already downloaded on your system.

Step 4: Finally, select the USB drive and drive MBR system (if you have a single one plugged in, it will be selected by default, if you have more than one, click on the dropdown menu and make a selection from the list) and click on the button Make it Bootable .


That’s all, the tool will now format the USB drive and copy all the Windows installation files to it and make it bootable.

You can now plug in the device into your system and select removable drive as your first boot selection preference in your BIOS and install Windows 8.

My Verdict

Although there’s an official Microsoft tool to create bootable USB drive from an ISO image, WinUSB maker’s portable nature and ease of use drew my attention. Furthermore, WinUSB gives a bit of an extra control to the user than the official tool for the same.

  2. thanks ashish. a very much needed guide

  3. Thanks for the Info…It really helped.
    By the way, I’m just curios wheather I’l be able to use back the USB as a normal USB again after I’m done with the bootable process.
    Do I need to format it back in FAT to use it for normal storage purpose?

    • After you have successfully installed Windows 8 just plugin your USB drive in Windows 8 (any other version of windows will also do) and format it as you format any regular USB drive.
      I would suggest you use NTFS as the File System

  7. Thank you Ashis! Brief and clear! I needed a bootmaker and now I know exactly which one is gonna work for Windows 8 installation :) I think I’m gonna keep returning to your site as I frequently see you on my google search result! Today is the first time I visited and I like it.

  8. BigJim1 says:

    How can we make a USB bootable Win8 that we can play directly from the USB bootable drive?. Not just one that we can install from?? One that will not affect my Win 7 installation in any manner.

  9. kumar says:

    Thanks Dear.. Thank you very much.

  10. Nithin Kn says:

    thanks dude

  11. Thanx bro

  12. GlennRogers says:

    Many thanks, this worked beautifully. Windows 8 is not running very nicely on my ASUS Tablet (EP121).

  13. Best thing to do is that if you are not willing to re-install Windows 7? Don’t bother fiddling with Windows 8 Beta versions.

    If you are wiling to do that or have a computer that you can use as a ‘testbed’, then feel free to use the Release Preview.

    Can I later delete the windows from my USB ?

  15. Chuta says:

  22. OwlCity says:

    Thanks mate!

  23. Jason says:

    What is the different between “Windows 8 Consumer Preview” and “Windows Developer Preview” ??? Kindly reply~

    • Tcat Houser says:

      The Developer Preview is the 1st (public) build. Think Beta 1. Consumer Preview is newer. Think RC1. (And you didn’t ask) Release Preview was the last, think Release Candidate almost Final. That is the last Pre-release.

    After an Adobe update yesterday my 8.1 installation gave me a horrible BSOD on startup – Error 0xc0000001 IIRC. Argh! Just before I got round to making a recovery disk!
    This should hopefully get me back on track – cheers!

  56. XJ says:

    May I ask… After you make the usb as bootable installer, can you still use the usb? as a removable drive?

    • @disqus_8duUwMPbUC:disqus Yes you can still use the USB as a regular drive. Just make sure you don’t delete any of the files that’s required for Windows installation.
      The best practice wold be to create a folder in the root and then save all the files in there.
