I didn't test it on Virtual box so I cannot say much on that. I see that your actual hard disk is too big as the Install.wim is 11 GB. Did you give enough space for your virtual hard disk? And could you take a snap shot of the BSOD message as soon as displayed? Don't use EasyBCD to boot from ISO in Virtual Box or Vmware. It doesn't work. Edit: I found a similar problem on Virtual Box support forum. http://forums.virtualbox.org/viewtopic.php...696&start=0 It might be helpful. Thanks for the quick answers you are providing. The hard drive on the virtualbox is 40GB so thats not a problem. the BSOD screen happens in a blink of an eye. I will try to capture that. I didnt use EasyBCD.
