Either you should have a recovery CD/DVD (maybe even a whole set) or there is a hidden partition on your HDD that contains the recovery data.
I'm not absolutely sure if I remember this correctly but I think you can access this partition by pressing F8 while booting. Then you should get a menu where you can chose to burn the recovery to disks (3 DVDs).
With these DVDs you can restore the initial system. Backup your data before you restore the recovery because your data will be erased!
