Hello
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).

Do you meant that your Mac turned off completely?  I don't think that's related to VirtualBox.

Try resetting the SMC first.  Which kind of Mac is it?

If it's a newer Macbook or Macbook Pro that has a non user serviceable battery, then plug in the power then press and hold the power button for 5 seconds or more.  Release.

If it's not a Macbook or Macbook Pro, unplug the system then hold the left shift control option keys then press and hold the power button for 5 seconds or more.  Release.

If it's an older Macbook or Macbook Pro that has a removable battery, unplug the system, removed the battery, then hold the left shift control option keys then press and hold the power button for 5 seconds or more.  Release.
