[SOLVED] Dell Optiplex won't boot into W10; don't know local Admin pass. FIX: I was able to change PW, went in recovery mode, did reset keeping settings&files

It did run. No change. I was hoping to get you the memory.dmp, srt files, etc. but onedrive started acting up.
 
Well it crashed with the same error 21A, but after that, instead of system recovery crashing, it put this screen up

Well, the dism.log indicate that some repairs were done. Lets see if the System File Checker runs:

  • Download the enclosed file
  • Save it in the same location FRST64.exe is saved.
  • Run FRST (FRST64) as you did before
  • This time around Press the Fix button and wait
  • When finished, a log file (Fixlog.txt) will pop up and saved in the same location the tool was ran from.
Please attach this file in your next reply.

goes through to 100% and then says windows resource protection could not perform the requested operation.
shouldn't we do a straight sfc with the /off switches?
 
No integrity violations but still won't boot. error 21A as before

then it says it has to go into recovery mode. press F1

I press F1 and it says a required device can't be accessed. 0xc000000e

but I have the windows media on a usb in!!!

confused.....

I'll get the cbs.log...
 
You tried this before. It is saved as c:\sfc_log.txt.

sfc /scannow /offbootdir=c:\ /offwindir=c:\windows /offlogfile=c:\sfc_log.txt

Try also to boot in Safe Mode. That will exempt drivers from hardware.

bcdedit /set {default} safeboot network
 
i saw that too.

I think it's confused when trying to run things from a recovery disk.

why is it not entering the recovery environment and saying a needed device is missing?
 
Run these commands:

Diskpart
list disk
select disk 0 (That is disk zero)
list vol
Exit

Take a photo and upload it.
 
I don't know why, but that disk shows 0 bytes Free. Perhaps that is the problem. That is how the system sees it, even if it isn't true. It can't even boot to the Recovery partition. In my honest opinion, you will need to reinstall. I am enclosing the instructions. Make sure you convert the drive to GPT in the process.
