Create Windows 8 bootable installation USB drive fails

To create bootable USB installation drives I have always been using the Windows 7 USB/DVD download tool from Microsoft stores

http://images2.store.microsoft.com/prod/clustera/framework/w7udt/1.0/en-us/Windows7-USB-DVD-tool.exe

Recently I tried to create a Windows 8 installation drive and the process failed right after formatting the drive but before copying of files started.  The app would just die and disappear.

I had the same issue regardless of the source ISO, OS version of the ISO or the USB drive I was using.

The cause of this was the Sophos Endpoint Protection on access scanning running on the machine I was using to create the boot drive.

The behavior of the Windows7-usb-dvd-download-tool.exe gets flagged as suspicious behavior.  To prevent this you need to authorize the file in the local authorization manager (if you have privileges) or through policy in the Sophos enterprise management console.

Add the authorization on the local machine

  • Open the Sophos Endpoint Security and Control Application
  • Select Configure anti-virus and HIPS
  • Click Authorization
  • Select the Suspicious behaviour tab
  • You should now see the Windows7-usb-dvd-download-tool.exe in the known applications pane
  • Click the add button to move it to the Authorised applications pane


If the entry is not listed you can add it manually by clicking the New Entry button and selecting the file.

Add the authorization by policy

  1. Open the Sophos enterprise Management Console
  2. Select the relevant Anti-Virus and HIPS policy being applied to the relevant machines
  3. Select the Suspicious behaviour tab
  4. You should now see the Windows7-usb-dvd-download-tool.exe in the known applications pane
  5. Click the add button to move it to the Authorised applications pane



Note in the screenshot there are two entries.  This is because there are two minor version of the file (1.0.24 & 1.0.30)

I had the same issue with Windows 8 upgrade advisor not being able to create a bootable USB drive. I am using a 16gb drive. After cleaning the drive, using diskpart, I created a 4gb partition on my flash drive. The upgrade advisor is now able to create the bootable flash drive.
