MBP doesn't boot...

Okay, I just wrote an extremely long and detailed post but my lovely temporary Dell computer I'm writing this on decided to BSOD and I lost it.

Here's the short: I erased the free space on my hard drive because it OS X claimed it was full even though it wasn't. I was forced to quit at the end while it was stalled at "Creating temporary file" for 3 hours. I restarted the computer and this was the result:

YouTube - MBP boot attempt

It boots to the login screen, gives me a warning that the hard drive is full, allows me to log in, but then doesn't load any icons, the dock, or the menu bar. Key commands like cmd-shift-Q still work to log out and stuff.

Anyone have any ideas or know how to fix this?

Thanks!

Oh and also, it didn't switch from the login image (that graffiti thing) to my desktop background, which is a jungle cat of some sort, but the mouse cursor still works, as you can see in the video.

 

Put disc one of the restore discs in and press and hold D after the chime to run diagnostic testing. Let us know what it comes back with.

 

I had a similar problem like this happen to a friend. The only way he was able to fix it was by reinstalling OS X from the CD.

 

I'll run diagnostics now, but I already tried reinstalling OS X and it doesn't work because the drive's full and I can't format it because it's not backed up and I can't back it up because it won't boot and I don't have an enclosure at the moment.

I'll post the results asap

edit:



^this disk? Holding D at startup doesn't do anything. It didn't with a copy of Snow Leopard either...

 

Well yea what I meant by installing OS X was formatting and installing it fresh. That was pretty much the ONLY option for my friend so if you didn't back up you are SOL. I think the Applications DVD is the one you have to insert, the one in the pictures is the OS X install dvd.
