Sherman, you can try this below if you think the MRCBT.SYS file, or lack thereof, was the cause of your problem...
First, make sure you have an image to go back to if you've done a lot of work with the older restore point... IMPORTANT! Then mount the troubled DIFF image under your LIVE System and check to see if MRCBT.SYS is located in that mount point under WIndows/System32/Drivers. If it is, that wasn't your non-BOOT problem. If it isn't, you can try the procedure below to try and resurrect your DIFF time point. Before you do that, identify (via browsing) a v7 time point that you know has the MRCBT.SYS file within it.
Restore your System to the problem DIFF time point. While in the Recovery Media, mount an image time point that you know was right after your v7 upgrade. Examine that mount point and see if MRCBT.SYS is located under Windows\System32\Drivers. If so, copy that file to your just restored C:\Windows\System32\Drivers folder and reBOOT from the Recovery Media into your LIVE System... if the missing file was the problem, it should BOOT.
If it does, enter Reflect and use the update feature to get you to the most recent offered update (2089, I believe).
