Windows 10 Install Fail on MacOSX Yosemite 10.10.5

[fletch23]

HELP!

I've spent an entire day now trying to install Windows 10 on my Mac after installing the new virtualbox and following what I thought were all the proper instructions. It took hours for the actual install, then it failed. I tried to restart it, so not sure which vbox.log is the right one.

Also when I start the Windows 10, two windows show up, Windows 10 [Running] : 1 and Windows 10 [Running] : 2

I have attached the latest vbox.png and vbox.log and my own screen print of what I saw last when it failed after the restart.

I'm sorry I have to do this, but please close the VM before you post the VBox.log. And please ZIP it first. As for the other two pictures, they were not needed and I've removed them as well. Save a (virtual) tree or two...

So, follow a "start the VM from cold-boot"/"observe error"/"shutdown the VM" cycle (press "OK" in the Guru screen). With the VM shut down completely (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log". Save only the first "VBox.log", ZIP it and attach it to your response (see the "Upload attachment" tab below the reply form).
