    removing lock and security from a locked C: drive


    Pulled this C drive from my windows 10 computer (which is stuck booting) and have plugged it into the usb on another windows 7 computer

    want to unlock and remove security so that I can then do a windows repair to the drive and get it booting properly

    Trying to remove
    the lock and security but not sure exactly how.

    trying to unlock the drive and getting this error:


    "an error occurred while applying security information to: E:\Program Files and E:\Program Files (x86) and a bunch of other folders

    i plugged the drive into the usb port on another computer and started to unlock it following these direction exactly:

    Follow these steps from the administrator account:

    a. Click “Start” and click “Computer”.
    b. Right-click “C” and click “Properties”.
    c. Click the “Security” tab.
    d. Click “Authenticated Users” and click “Edit”.
    e. Select “Authenticated Users” again.
    f. Under “Permissions for Authenticated Users”, click “Allow”.
    g. Click “Apply”.
    h. Click “Yes” when prompted by a “Windows Security” dialog box.

    Should I have been trying to unlock "SYSTEM", not "Authenticated Users"?

    What did i do wrong?

    How do I properly unlock the drive and reset the security so that I can access this drive and then run win10 repair to fix the errors?

    Sounds like you may need to take ownership of the entire drive system. Still seems a risky way of doing a repair.
    How exactly is it 'locked' ?

    this desktop is stuck in a bootloop after an automatic window 10 update

    "reset this pc" tells me the drive is locked

    system restore does not work.... "need to specify which installation to restore" but no options are available

    automatic repair does not work

    reset this pc tells me the drive is locked

    pulled the drive and mounted it to another computer and ran chkdsk /f on it, it made some repairs and when i reinstalled it and tried to boot, i'm still getting the same problem.

    when i run chkdsk /f a second time , no errors are found

    used rufus software to load windows 10 iso to usb drive but it does not work....seems like it's not booting from the usb.

    used win 10 media creation tool to create a bootable usb drive from win 10 iso, will not boot from usb drive

    created a win 10 dvd from iso and it will not boot from dvd

    cannot enter bios thru startup for some reason and on the troubleshooting advanced options section, there is no option for startup settings to get to bios that way.

    going back to previous build does not work


    system image recovery failed: system cannot find file specified (0x80070002)

    System File CHecker tool from bios tells me: " there is a system repair pending which requires reboot to complete" but i've rebooted 10 times and nothing changes.

    when it attempts repairs and fails, it always takes me to a page asking what language my keyboard is, i select US and then it takes me to the troubleshooting page.

    how do i fix this boot looping problem?

    dell X8700-1257BLK

    Can you get a "Command Prompt (Admin)"? If so copy paste the following and press enter.
    dism /online /cleanup-image /restorehealth

    I can access cmd and tried your instructions and got this response.

    Error 87:
    The restorehealth option is not recognized in this context.

    You must only use the restorehealth option on the computer that Windows was installed on, as it will only recognise the mobo that it was registered with.

    I mounted the drive back into the desktop pc and from the command prompt I see this:


    x:\windows\system32>


    if I type in C: , I get this:


    "The system cannot find the drive specified."


    If i mount this C: drive to another computer, I can see/open this drive as E:


    How do I locate the drive from command prompt and change its letter back to C: ?

    You could try restorehealth option after your above x then change if successful from x drive to c drive as shown.

    I guess you don't have a backup image?
