Hi all, I'm really bummed out right now. After installing ubuntu on my macbook and deciding it wasn't to my liking, I wiped the linux partitions and tried to have boot camp merge the partitions before installing windows. Unfortunately it's giving me the following error:
"The Startup disk cannot be partitioned or restored to a single partition. The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by boot camp assistant for installing windows."
This happened a couple months ago. So at the time I booted via the Mac dvd and tried to non-destructively merge the partitions with disk utility, but to no avail. Not having time to do a proper backup and whatnot, I didn't go about reformatting and put this off for a while.
Come this week, when I do have time for all that fuzz the macbook refuses to boot the mac dvd

I've no idea why it wouldn't because a) there are no visible scratches on my boot disk, and b) the drive mounts other CDs fine.
So my question is quite simply what to do? Non-destructive method would be ideal but if I must I would reinstall OSX.
