Mac OS Partition not showing

I've just turned on my Macbook Pro and it booted into Windows 7, which is wierd as it always boots into OS. Anyway, I assumed this was just a glitch, restarted the laptop and held down the option key. However, when the bootcamp screen comes on, it is only showing the W7 partition. The HDD shut down from OS X fine when I turned it off last night. Any ideas on what to do next?

Unibody Macbook Pro 17" Summer 09 Revision, Mac OS X (10.5.8), Dual Boot Windows 7 (beta)

Start up from the install disk that came with your computer. Click continue in the first window that comes up. Select Utilities from the finder window. Run disk utility. Your HD should appear in the sidebar, with your partitions below it. If your OSX partition appears, highlight it and run repair disk. If it doesn't appear we have have a whole different problem. Come back with your results.

It appears but first aid fails. It says the catalog file entry was not found.

Yes, both the Windows 7 & Mac OS X partitions are showing. The W7 one is fine, it's what i'm on atm, the Mac one won't seem to repair.

Yahtzee! Damaged drive.

You can try a utility such as Disk Warrior to resurrect the drive. For now I would just run from the backup drive especially considering that you have work due.

Sounds like a job, as DPC says, for Alsoft's "DiskWarrior" to me, if you can't fix it by booting from your OS DVD and running Disk Utility to "repair" the drive (not just "repair permissions").

Cheers
