Trying to set up a new Windows 10 64-bit guest on my MacOS host, as soon as I pick the windows 10 iso file (obtained from the microsoft download site) I'm hit with this screen, and nothing further seems to happen.
What have I done wrong? I've followed this process a few times from a windows host, but never a mac host - I'm running an iMac on MacOS High Sierra.

Hmm... I've seen that with Linux guests, not a Win10. We're going to need to see a VM log from a complete VM run:

• Start the VM from cold-boot (not from a paused or saved state) / Observe error / Shutdown the VM (force close it if you have to).
• With the VM completely shut down (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).
