You will need an external DVD burner. I have not looked at trying to use a Windows 7 software to read an ISO to load from but that may not be possible anyway. You can download the ISO to the Duo then transfer the file to another machine that has a DVD burner and ISO burning software. In case you don't know an ISO is a disk image. The Windows 8 upgrade will download as an ISO file that then needs to be loaded by software to be read or using Explorer to burn the disk image to a DVD/CD. Some ISO's are for CD's but the image for Windows 8 is a DVD.
Before you begin make sure your BIOS is at the latest release for the Duo. I think that is revision 4 or 6. If it is not then do that while you have Windows 7 functioning as it may be harder or not possible to do under Windows 8. The BIOS update is available under the Driver section of the Dell Support site for the Duo. Plug the machine into AC power when you do the BIOS update as it will geneally refuse to update unless you do this. Make sure you follow the directions carefully as if you blow the BIOS update the machine is pretty much worthless afterwards. The machine will reboot during the BIOS upgrade and if you don't want to do this a professional would be recommended. It normally only takes about 15 minutes or less to do the BIOS upgrade.
Ok, so this is a bug driven by the difference between the Windows 8 and Windows 8 Pro features. To fix this:
1.) Go to the start screen
2.) Type CMD, right click the icon that appears and "Run as Administrator"
3.) Type "bcdedit /set testsigning on" and press enter
4.) Restart and touch will work.
This enables test mode but it will get you by until MS releases a fix (hopefully)

Any tips on installing Windows 8. Did you update or do a clean install to another partition. This is what i usually do in case of horrors!
In my case I purchased the upgrade version of Windows 8 Pro. Keep in mind I did this months ago but I believe I had the upgrade format the drive and then install. I had downloaded all the Windows 7 drivers for the hardware and had them on a USB drive. I did find one missing driver but a Dell support tech knew what I was referring to and posted a link to it. It was for the motion detection system. All of the most recent drivers at the time worked great on the Windows 8 system. I still don't understand why Dell will not support the Duo with Windows 8 but it is their call even if it makes no sense.
Most important was make sure you have the BIOS at the most current version BEFORE you attempt to put Windows 8 on the system! I have not tried to upgrade the BIOS since the system was converted and I know that sometimes the BIOS software will do a version check before it upgrades and not allow you to upgrade a system that has the "wrong" OS on it. I think in this case it was more a matter of some of the things that Windows 8 does would expect the BIOS to be more current.
Yes the drivers were part of either Windows 8 Pro or else I used the Dell Windows 7 ones, either way it is working. We don't use it but it is reporting correctly in the Device Manager.
Thank you for this info. This did enable the touchscreen to work. It does seem that I am not to begin typing in desktop mode and it begin to search. I seem to also have lost the ability to get off the desktop and to the tile page as well. This things did work before I put it into test mode so I concluded that what caused the change. I am open to suggestions though. Also I can no long just click on a web link that is on a ed page and be linked. Thinking I need to reverse this and try another approach to get the touchscreen to work. Any suggestions on these matters?
Sorry i am new to blogging. I though my statement would go directly under the suggestion I followed.I followed the advice of Edward Clark and set my duo up in test mode to get the touchscreen working and then I notice the things that are noted above.
