Trying to give something back to the Community...
So I thought I’d give downloading the ISO from Connect another try and I’m pleased to say that this time Hyper-V likes it and the install has got a LOT further (although not finished as I type this)
You shouldn't get any issues... I downloaded the ISO from Connect and got it running on Hyper-V fine. Running it on my laptop now I was so impressed !
The sooner Windows 7 is released, the better. It is so much better than Vista in nearly everyway.
