    Critical System driver is missing or corrupt. Automatic repair fails.


    I used to fix computers awhile back. Decided to help out an old customer, who can't find anyone to fix his computer during the Christmas period. He says its stuck in a automatic startup repair loop. And the last thing he did on the computer was click restart to install some windows updates. He said he tried a few fixes he found on youtube fixboot and fixmbr etc. But none of them worked. The Last thing he tried was fix boot problems using a macrium repair disc. And this is where I pickup the computer.

    I using macrium myself to create images of the 2 HD's in the computer. And checked the health of the HD's with HD Sentinel. And health is good with them. I then tried startup repair options and tried to get into safe mode. System restore doesn't work either.

    I attached a screenshot of the screen it boots into atm.

    What would be my next step to take to tried and fix this computer?

    Hi subby,

    Is SFC tried?

    The error code means there's a bug in the mentioned driver, likely due to improper replacement.

    I have attempted the SFC scan, and have just done it a 2nd time. When finished it says 'Windows Resource Protection could not perform the requested operation.'

    Any chance there's a restore point or system image available from before the update?

    Nope no system image, and I tried System Restore, it seems it was disabled. I have tried Reset and it failed. I think i will have to do a clean install.

    Since you know how to get to a Command Prompt, try running chkdsk x: /x /f /r (where x: is your OS drive).

    Show us the output of diskpart as well.

    diskpart
    list disk (post result)
    sel disk n (where n is the OS disk)
    detail disk (post result)
    list par (post result)
    exit

    chkdsk results. 'Windows has scanned the file system and found no problems. No further action is required.'

    So you ran chkdsk d: /x /f /r

    Try these, in order:

    bootrec /scanos
    bootrec /rebuildbcd
    bootrec /fixboot
    bootrec /fixmbr

    Capture results and post please. If that doesn't work or the rebuildbcd command fails again, follow the directions posted here by Vijay B:
