My computer won't load after boot camp issue!

Okay, so basically I can't even use my MBP right now and I'm not sure why.

Here's the story:
I was installing bootcamp, partitioned 15GB towards Windows.. but then I realized I didn't have the CD for XP, so I deleted the Hard Drive icon that appeared after the partition and figured it would get rid of it (not sure if it did).

Anyway, when I finally got the XP cd (XP Professional), I went straight to "Start Installation" in Boot Camp, but when I got there, I could only see my OSX hard drive (so I guess the partition deletion worked?), but anyway, I can't format that since I need a lot of stuff from it and it was asking me to format it, so I exited the installer and it automatically restarted.

Upon restart, my MBP then goes to a gray screen, then to a black screen where an underscore just blinks at the top left corner forever (up to like 10 minutes, as long as I've waited, at least).

Anyone have this issue? I can't even see what I could have done wrong.

Thanks!

 

Also, to add to this, when I hold Alt (Option) while it's loading, it'll bring up a choice thing to choose which HD I want to use, but the only one is Windows, there is no option to load as OSX!

Really starting to panic now, could I have lost all my data?

 

How do I boot with the OSX disk? I tried inserting it then turning on the MBP, but the same thing happens. I've held ALT, but Windows is still the only choice..

EDIT:
Nevermind, I just needed to wait for it to load. Basically, it brings up the MacOSX install, then asks me where I want to install to, when I press continue to select which drive I want to install to, there are ZERO options, and I can't hit continue.

I think I need to take it in at this point, anyone know a solution before I do?
