Hello. I've problem with my OS Windows 7 SP1 x64. Few days ago I've black screen with cursor (CTRL+ALT+DEL don't work). I replaced cmd.exe and utilman.exe. After system start I logged out, and I used WIN+U and started cmd. I created new user account and at new account everything was fine except malware i supposed. Then I used COMBOFIX and after scanning, system didn't start. Combofix deleted few system files but it didn't replaced them. Windows Auto-Repair found few errors, missing or corrupted files, but it can't repair. I replaced them those files manually from W7 DVD. After that i have Blue Screen with STOP: 0x000000007B (0xFFFFF880009A97E8, 0XFFFFFFFFC00000034, 0X00000000000000, 0X00000000000000). I tried to repair mbr through cmd via bootrec, and manually via BCD. I can't do anything like SFC or DISM. CHKDKS /f /r didin't fix anything. I've tried everything but i can't install new OS because i have few important things in this computer (programs). It must be work properly.
After sfc /scannow /offbootdir=C:\ /offwindir=C:\ once i have pending repair, once security resouces function can't run repair service.
After dism /image:C: /Cleanup-Image /Restorehealth - i have error 87
Bootrec.exe /buildbcd shows 0 OS found
Bootrec.exe /scanos shows 0 OS found
I have FRST report but i don't see anything wrong.
