I was updating to mountain lion when it stopped the installation and marked an error in the disk, now the computer does not work....what can i do?!

Also the computer does not find the HD since it marked the error.
I need a way to either reinstall OS Lion or to complete the installation of Mountain Lion successfully.

Depending on what OS the computer had on it, either boot into the Recovery Volume using command - R or by holding down the option key and selecting the Recovery Volume. If the computer was using pre-Lion OS, boot from the disks that came with the computer.
Run Disk Utility and see if you can repair the hard drive. Also try Repairing Permissions. If successful, try a normal restart.
