Looks like maybe my troubles are being felt around other places as well...  Glad I am not the only one with issues.  And it also looks like Microsoft has pulled one of the Hotfixes for now as well...  I think I'll try again once all this is worked out!

"We've received reports that some customers may be experiencing an unusual reboot cycle after installing KB937287, the servicing stack update we released last week. To prevent further instances of this issue, we temporarily stopped automatic distribution of the update and are investigating solutions to the problem. We believe this problem only impacts a small number of customers. We are working to identify possible solutions and will resume automatic distribution again after we address the issue."

I might not have been having the reboot problem, but I did have the same 'no boot' part happen as mentioned in the article.
