As far as I know, I am using a Universal disc that was purchased along with several others by the university I work at. I have used this discs on a number of other MacBooks and have yet to have any problem with them.
Again we need to "pay attention to detail here".
You mentioned in your initial post that you were working on MacBook Pro, and in your 2nd post you mentioned "MacBook's".
MacBook Pro's & MacBook's are NOT the same computer model...so we need to be exact regarding the disk's.
If it turns out you are using "model specific" Mac OS install disks...they may have worked fine on the MacBook's you worked on previously...but they may not work on a MacBook Pro.
BTW...model specific Mac OS install disks are usually a grey color, and will state what model Mac they are for...such as "MacBook", MacBook Pro, etc.
Universal install Mac OS disks will usually be a bit "fancier" looking...but probably won't be grey. For example, my OS 10.5 Universal install disks are black with a big X & stars on the disk.
Sorry for all the details...but we have to be sure you're using the correct disks, before we can figure out if the problem is the hardware or not.
Hope this helps,
