Hi guys hope you can help me resolve my problem. I have an old Macbook and I wanted it to upgrade my OS but when I upgrade it I have this problem.
 
Aw so you mean i have to replace my hard drive ?the problem is i don't have a back up of my OS do how can I format my new HDD ?
A 2008 Mac should have install media, unless you've lost it. You can boot from that and run disk utility to format a new drive and install OS X onto it.
