I did a start-up in Safe Mode. After initial fail, it went to a screen where I could choose Launch startup repair (recommended) or start normally. I chose Launch startup repair and after getting a blue screen where it couldn't load the HIVE file as in post #8, it gave me a screen for System Recovery Options where I could choose Startup Repair, System Restore, Windows Complete PC Restore, Windows Memory diagnostic Tool, Command Prompt or Recovery Manager. I chose System Restore(Restore Windows to an earlier point in time) and Restart. It just looped around to the screen that said start up failed and gave me the option of launch start up repair or start normally. When I did my recovery as stated in post #1, I did a reformat and restore to original factory install so wouldn't all earlier good configurations be wiped out? SeaTools gives the option of erasing the entire disk. Would that be a good idea to try?
