Where does boot camp put the partition space?

I tried doing bootcamp, partitioned 100GB, but was taking over an hour, everyone says a few minutes, so i quit, and now that 100GB is somewhere, but not partioned because disk utility just shows the 1, I want to know how to get it back, when I look at storage in about this mac, it says i have 27 out of 500, which is fine because that should be it, but that 100 is somewhere, please help

If the amount of space being reported by Disk Utility is correct, then the 100 GB partition was not created. Your hard drive likely has disk errors which is why it was taking so long to create it. You need to verify and repair your hard drive before doing any more partition work.

I have tried repairing and verifying, the problem is before it happened i had like 128 or so free, chose to give windows 100, theres no partition, but i no longer have 128 free, now its about 27, so that 100 went somewhere, i just cant figure out what happened

What does the partition tab show when you use Disk Utility? If possible, include a screen shot so we can see what's going on. You didn't mention which version of OS X you're running but if you're using Lion, ML, or Mavericks, you'll need to boot to recovery first and run Disk Utility from there.

Also, after you get this issue sorted and all the space returned to the OS X partition...

With only 128 GB free space on a 500 GB drive - it is unlikely that you're going to be able to create a 100 GB partition for Windows - because your data is already using that space on the drive - without either defragging the drive or doing an erase, install, and restore.

Plus the fact, that with only 28 GB free out of a 400 GB partition, OS X is going to run like molasses in the arctic.
