Welcome to the Apple Support Communities
Lion uses Recovery to reinstall OS X. Press Command and R keys when your Mac starts, open Disk Utility, erase the drive and reinstall Lion. The other Mac has probably got its hard disk damaged, so take the Mac to an Apple Store
What damages a disc like this?
Hard disk damages with its use, so all the hard disks will damage. That's the reason you should make backups
I have all my data backed up, can i reboot it from Time machine, or a back up?
What OS X version uses your Mac with the hard drive damaged?
