|"I dont have a disk for this , i was never givin one when i purchased it"|
You mean you never created the discs. Very few, if any, OEMs supply discs anymore. Instead, they put the files on the HDD & provide a software program that allows you to create your own set of recovery discs. Unfortunately, most people never read the documentation that comes with their PC & the discs never get created.
