Your ISO is fine, what issues are you having? I found I had to get a little creative with some driver stuff, but once I got past that everything was running well.
No Driver problems. All installed correctly and they are seems to be OK. Many Icons from All apps and also Start Menu didn't working, apps didn't start! Checking System Properties, it says: Windows 8 Pro It's activated used MKT. Will re-install on an new HDD and see what happen than.
I see you have a digital signatures tab as well. Why not look at that one? If it has a valid signature from MS, it can't be altered.
