I can't update to OS X Mountain Lion because I accidentally erased the Recovery HD. How do I solve this problem?

I tried to update to OS X Mountain Lion but it's not allowing me to do so. After calling Apple Care, I realized it's because my system is missing the recovery partition I should have. I remember I deleted it because I didn't know what it was. What do I do?

Yes, I can. I called them and they told me to back everything up and then call them back. That doesn't sound optimistic, right?
Yes, it does. It appears that they're going to have you run Disk Utility and wipe the MacHD. However, how you do that w/o a Recovery HD is beyond my ken. As for backing up, I wouldn't rely on Time Machine, but instead make a bootable backup/clone on an ext FWHD, ensure that it can boot the machine. Then, you can use that to wipe the MacHD.

BTW, in the future, don't remove stuff you don't know anything about.
