Here is the procedure to run
I had a corrupt syst volume from a bad shutdown and I couldn't load windows ,couldn't enter safe mode or recovery console either , coulden't even access a c> prompt nada . It would post then just a blue screen and a useless pointer that was it.
" In certain situations it becomes absolutely necessary to do as many as 3 separate startup repairs with a system restart between each repair to completely write boot files to the "new" location and if the process is interrupted or not completed you will be right back where you started, with a PC that will not start-up at all." Win 7 forum
I created a syst rep. disk CD on my other computer and used it to fix this one . I had to run system repair about 8 times to fix it
I almost gave up and bought another HD. Some times it would lock up would have to re boot it sometimes it would say it repaired the system but after about 6 pr 8 times running it it fixed my system it's been good for 2 wks now
