We all hate errors that its way intersect with us, but what if you faced an error when you are powering on your VM !
I know how you feel now.
Anyway, such an error that apparently sounds like a long time of troubleshooting is needed, can be handled with a very few steps.
- Open the VM Settings.
- Remove the virtual DVD Drive
- Re-add the Virtual DVD Drive
Try to power on your VM again, and everything will look fine.
