I'm new to this so excuse me if this is obvious.

I'm trying to install Windows 8.1 onto MacOsx.

I'm getting the message:

Your PC needs to restart.
Please hold down the power button.
Error code 0x000000C4

Any ideas on what to do next?

Select Windows 8.1 as the guest OS version. Don't select Windows 8.0.

If that doesn't help then provide a VM log file: Right click VM in GUI, select "Show Log", save "VBox.log" (only) to a file, zip file and attach here. Make sure the VM is shut down before you collect the log of the session.

Thanks!

That was it.
