I have a early-2009 iMac that I wanted to run windows 7 on. Naturally, I used bootcamp, but when I reached the installation phase, I messed up and deleted the OSX partition. I restarted the iMac in recovery mode, and ran disk utility to find that the hard drive wasn't even recognized, not even one partition. Thankfully, I kept a time machine backup, but I can't even use it because there is no drive to install it on. What do I do now?

Does the physical hard drive show up at all? Select it, and repartition.

It doesn't show up at all. The only drive that does show up is the OSX recovery disk

SH means, if the physical drive shows up in Disk Utility. Since the recovery partition is hidden on the internal drive, the physical drive has to show up there.

The physical drive does show up, but when I run first aid, it get a message saying: "problems were found with the partition map which might prevent booting."

The drive itself is a 320GB Hitachi SATA drive, but it's only showing that it has 859MB.

When you have selected the physical drive in Disk Utility, try erasing that and reformatting, using the GUID partition table format.
The new Mac Pro has up to 30 MB of cache inside the processor itself. That's more than the HD in my first Mac. Somehow I'm still running out of space.
