debug during start of the system, and trying to open the CDROM drive

ReactOS Freezing when trying to open CD from My Computer.
Only mouse moves, nothing else work (total hang)
I mounted the images that I made, later I enabled Physical drive in VirtualBox.
sometimes icons of files on the CD are shown, but trying to run something from it crashes ROS.

VirtualBox GUI Version 3.0.12 r54655
