You have to go to BIOS settings. It may be any key like del, f12, f1, f2,f10 etc try it. When you get to bios setup first reset it to defaults. Now go to boot section, you can see the boot priority. Change the boot priority of the CD drive to first followed by the hard drive..
Now you can boot form CD/DVD or hdd
Please provide more info like Presario number like that. Serial number is of no use.
I think I have helped you...
