I can't install OSX Lion from DVD, because I receive an error I tried to install OSX Lion from DVD, but when I boot from the dvd I receive bootstrapper crashed error. How can I fix that? Maybe the disc is scratched, or what's the problem?

Thank you!
You can do a clean installation from the recovery partition:


Restart or start up and hold ⌘R after the screen turns on
Erase the drive from Disk Utility (without it the next step would only do an upgrade install)
Choose Reinstall Mac OS X
