I was able to solve this problem using Method 3 at this Superuser post. I had to run the fix more than once. The author (Mohammadhassan Esfahanian) skips a couple of steps, so I will be very detailed for the novice:

1. Boot from Windows 7 installation DVD/USB

2. Accept language

3. Repair your computer (very small, at bottom left of logo)

4. Troubleshoot

5. Advanced Options

6a) First, try Startup Repair (try 3x if not work the first time)

6b) If 6a does not fix, use Command Prompt and follow Mohammadhassan's instructions (same link). Note that he says that you might have to repeat more than once - I did it four times before it worked.

But it worked! Thank you Mohammadhassan.

6a) First, try Startup Repair (try 3x if not work the first time)
(Attempting Repairs might conclude "Cannot repair..." try again then move to 6b)

6b) If 6a does not fix, use Command Prompt and follow Mohammadhassan's instructions (same link). Note that he says that you might have to repeat more than once - I ran StartRep four times (and never saw any sort of SUCCESS message - each time it said that it could not repair the PC)

But despite the Cannot Repair messages, it worked! Thank you Mohammadhassan.
