When the hard disk is dysfunctional or has crashed, the laptop cannot detect it. The error message 'No hard disk drive 0' will appear as a result.
After the disk has been read goto the windows sign at the bottom left of the screen and click it, goto 'my computer' or 'computer' and click it, finally click where it says DVD and the disk will start playing.
As with all systems, your disk is probably dirty. Clean it and try again.
\Try restarting the computer. If that doesn't work, the disc is probally broken
