I've created a recovery iso and burned it, But I can't use it.
When booting, right after the windows boot progress bar it shows the following error, and reboots when I click OK.
I've tested my Iso on a VM and two physical machines, including mine.
Please set registry key HKLM\software\microsofft\.NETFramework\Install Root to point to the .NET Framework install location.

on my Windows Install, the value is C:\Windows\Microsoft.NET\Framework64\, which seems to be the good path, it contains v4.0.30319 (and older versions).
Thanx for any help/pointers, I'd really like to fully test this!
EDIT: I also opened a case, #00704221, dunno If I should have only done that and not posted here... But maybe I'll qualify for most hidden bug and win a Surface, who knows?
