Windows 10: My PC won't start and to do anything in advanced repair I need a password which doesn't work.

Recently my windows 10 pc wasn't able to start because of bad system config info. I messed up and changed security file in D:\Windows\System32\Config\Security\and now if I try to do anything in Advanced repair it asks for password, I type in the password and it doesn't work. I have a ton of my personal files in this computer and I don't want to lose it. Please help

:)

 

Windows doesn`t start. Authomatic repair doesn`t work.

Thanks again!!

I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

I`ll do it and I`ll be updating this thread when I have the report.

I ran SeaTools. These are the results:




Does it mean my HDD is useless?

Thanks for your answer, ken!

I deleted all my data. I had have it backed up.

I did a clean installation using the windows media creation tool (usb option).

No, I didn`t. I thought a clean installation would solve the problem.

After posting my previous message, I did it.





After chkdsk, I close cmd and tried to boot and the laptop just turned it off. This morning I`ve restarted it and automatically windows did a repair. Windows has booted and it seems that the repair tool has removed chrome and acrobat pdf reader (the only two programs I had installed after reinstalling windows).

Now Windows is installing updates and restarting my lapop, I`m kind of frightened. I don`t want it to happen again. Anyhow, I want to know what has brought the issue

I`ve been looking for information about the error code at the end of the picture and I didn`t get anywhere.

Hello everybody.
First of all, I want to apologize for my English, is not my natural language.
After a normal power off, my laptop didn`t run Windows normally and showed a blue screen saying
"Your pc ran into a problem and needs to restart. [...]
Stop code: BAD_SYSTEM_CONFIG_INFO"
After several restarts, the display showed "preparing automatic repair' and 'diagnosing your PC'. The result was 'automatic repair couldn't repair your PC' and gave a log file, D:\WINDOWS\System32\Logfiles\Srt\SrtTrail.txt.
I tried to restore windows to a previous point, but it was impossible (It was not possible to delete some file at D:\$MFT\. Error 0x8007007b).
I decided to reinstall windows. Only 24 hours after reinstalling windows, the same problem appeared again.
Following a friend`s advice, I opened srttrail.txt using cmd.
All error codes were 0x0 except "check installing lcu". That one was 0x17 (I don`t know how to copy the file and post it here. I`m sorry).
I searched in google for a solution but i didn`t find anything helpful.
Could anyone help me, please! Thanks
