I have an aluminum macbook, from made around January 09. The issue is i need to repair the hdd using the osx install disc. The problem is that when I try to do so, boot using the disc, it just restarts to the hdd, it will not boot from the disc. i try holding c and i have tried setting the disc as the startup disc and it just goes in this never ending circle of restarting and restarting. i've never seen this before so any help would be appreciated.
