Windows 10 Corrupted Registry Unable to Boot - How To Fix with CMD From Bootable Installation USB? DISM Issues

Hello all,


Last night, Windows 10 pushed an update. In the morning, it was stuck in a reboot loop where it would continually fail to repair itself.


I spent the day trying to fix it, but I couldn't find anything that worked. Currently, I am stuck with "The operating system couldn't be loaded because the system registry file is missing or contains errors.


Error Code 0x0000225 "


Here's what I tried that did NOT work (And made it worse):

  • Attempting to repair the BCD (Access denied)
  • Disabling automatic recovery mode in the BCD (Which now means I can't access command prompt from the native system, and I also can't reset the setting)
  • chkdsk (No errors found)
  • sfc /scannow (No errors found)
  • DISM /Online /Cleanup-Image /RestoreHealth (Various issues, highlighted below)

DISM is the most promising, but I can't get it to run. My only way to work on the system is to boot into the installation USB, and navigate to the command prompt. Whenever I run DISM, it errors "Error 50 DISM does not support servicing Windows PE..." and if I remove /Online with /Source:X:\Windows I get "Error: 87 the cleanup-image option is unknown".

I don't have an option to do a system reset keeping personal data, because I can't do anything with the native system. Initially I didn't want to deal with reinstalling 100 gigabytes of programs because of a windows update... But now that seems like it would have taken half the time.


I'd like to at least try using the DISM tool, but I can't get it to work from the install USB.


Any help is appreciated.
