Completely unable to boot into Windows after sudden BSOD
Hello all,
A few days ago my pc suddenly crashed showing a BSOD (attached is the file bsod.bmp with a pic of the BSOD that I took with my phone). I don't recall exactly what I was doing, just a common task like maybe browsing the news. After that I have not been able to start Windows ever again, nor in normal mode, nor in safe mode, nor in the last good configuration. I have tried a few things, none of which solved the problem. Here it's a concise list:
1) I ran Startup Repair from the System Recovery Options in the hard disk (from the advanced boot option menu after pressing F8). After running the first time, it stated that it cannot repair this computer automatically. In the diagnostic and repair details, I found:
Root cause found:
---------------------------
A patch is preventing the system from starting.
Repair action: System files integrity check and repair
Result: Failed. Error code = 0x17
Time taken = 160525 ms
Subsequent attempts to run Startup Repair again (after having done all the other attempts below) would instead terminate with the message "Startup Repair could not detect a problem. If you have recently attached a device to this computer, such as a camera or portable music player, remove it and restart your computer. If you continue to see this message , conatact your system administrator or computer manufacturer for assistance."
2) Since I had been foolish enough not to save any previous restore points or system images, the only other possibility left in the System Recovery Options was to go to Command Prompt.
I ran chkdsk /r /f d: a few times with a gradually declining number of bad sector found, until it terminated with no problems found. chkdsk /r /f c: returned no problems.
I ran sfc /scannow /offbootdir=c: /offwindir=d:\windows\
and I parsed the CBS.log extracting the lines containing [SR].A zipped copy of the resulting file sfcdetails.txt is attached (as well as sfc3.txt in which I further extracted only those lines showing potential problems). The choices of drives c: and d: are based on the output of diskpart

3) I booted from the Recovery DVD that I received from the pc manufacturer CyberPower and tried to run Startup Repair, which terminated unsuccessfully with the error message "This version of System Recovery Options is not compatible with the version of Windows you are trying to repair. Try using a recovery disc that is compatible with this version of Windows".
4) I tried the same as in step 3 booting from a DVD containing a .iso image of a retail Windows 7 Home Premium 64bit that I created as described in Windows 7 USB/DVD Download Tool. Also in this case Startup Repair terminated unsuccessfully, but with a different error message "Startup Repair could not detect a problem. If you have recently attached a device to this computer, such as a camera or portable music player, remove it and restart your computer. If you continue to see this message , conatact your system administrator or computer manufacturer for assistance."
5) Unfortunately I was not able to run the recommended dm log collector tool, probably because there are not enough resources to do so in the system recovery command prompt environment. When I tried, I got the error message "The subsystem needed to support the image type is not present". Please let me know if there is any relevant log that I can search through the command line of the recovery environment and I will provide them.
I guess my questions are: does sfcdetails.txt show what the problem is? If so, how can I fix it? If not, what other extra info can I provide and what other procedures can I try to solve the problem?
Thank you in advance,
Marco
