Mounting cd images in Windows 2008

I downloaded an evaluation copy of Windows2003 for my MCSE training tonight from Microsoft. The cd image is in an img file that of course can not be read by Hyper-V! Now I could burn the file to a cd and then capture the image within Hyper-V but that was too much work and I'd have to hunt for a blank cd. I knew that VirtualCloneDrive wouldn't work in Windows2008 as I had already tried this for something else earlier on, but I did find MagicISO - a package I had also used on XP - it said it would work on 64Vista and as Windows2008 seems to have a lot of similarities with Vista I thought I'd give it a go....I ran the install of MagicISO and then mounted the img file with it and explorer recognised the drive. I closed down the Hyper-V console, re-opened it and was able to capture my new drive for my new Windows 2003 installation. It's working very well - highly recommended.
Hopefully this will come in handy for others as I couldn't find any useful information on mounting a virtual iso img or cd image in Windows 2008
