I need urgent help. I tried to install VirtualBox on my MAC OS X with windows 7 guest.
The installation of the virtual box and the windows was successful and I also tried to use windows which worked perfectly fine. All of a sudden while using the machine, it turned off itself and now it doesn't start. I tried to start it in safe mode but nothing works.
Any kind of help will be really appreciated. (I do not have the MAC installation CD, the one I got when I bought it).
