jbaileyn, I need to thank you publicly for posting the great description of the problem you encountered and your step by step instructions for resolving it.
Apparently at about the exact same time that you submitted your post, I ran Norton Utilites' registry defrag tool on my 64x Windows 7 computer. After the program tried to restart my computer to complete the process, I only got the "blue screen of death." When neither System Restore nor Startup Repair would work to get my computer going again, I panicked.
After collecting my thoughts, I tried chatting with Norton. Their first level of tech support was unable to help me. I would have to wait a day or two for someone to get back to me. That wasn't going to work.
Then I used another computer to do a Google search. After just a couple of minutes I found your post. I followed it to the letter and it worked perfectly!
So, jbaileyn, thanks for posting so articulately about your problem and your handy solution. If you're in Northern California, I'll have to buy you a beer.
