Mouse glitch on 86Box
When using 86Box, the mouse may disappear during the GUI portion of setup. If this happens to you, then you must use your keyboard to navigate the GUI setup.

Black screen during setup on VirtualBox
After the "Installing and configuring devices" section of the setup, the screen will blackout and repeat such action. Seemingly, the only way to workaround this is to boot the CD and repair the install and proceed with the installation as usual.
