Windows 10: Can't reset my laptop from automatic repair

Hello everyone,

My laptop with Windows 10 is showing a blue screen with the error 0xc000021a every time I try to access the Windows.

When I turn on my laptop, it shows the message: 'Automatic Repair couldn't repair your PC' and the options: 'Shut down' and 'Advanced options'. I already tried to fix the computer on the 'Advanced options' using several methods that I found on sites and videos, but nothing I tried worked.

For example: if I choose 'Repair your computer' and then 'Startup Repair, it returns a SrtTrail.txt error. I also tried to run a lot of commands that I found on the internet in the Command Prompt to try to fix this error, but none worked. I also can't restore the system, because it says there's no system restore points available, and I can't boot into safe mode either.

So, I tried to reset the laptop on Advanced options > Troubleshoot > Reset this PC > Keep my files. I confirmed on 'Reset' and the laptop started to reset, but when it was about to 50% concluded, unexpectedly my laptop stopped the reset and went back to automatic repair window. I tried this procedure three times, and the same thing happened in all.

Does anyone can help me, please? What's happening, why can't I reset my laptop? What I need to do to be able to reset it or fix the blue screen so I can get back to use my laptop normally?

Thank you

P.S.: sorry for any mistakes in my text, English isn't my first language.

laptop doesnt boot automatically

This is what happened.

1. Did a repair install and later disabled hibertnate in CMD.
2. Enabled legacy option ROM in BIOS.
3. After a few times startup ( i used the system in such mode for 5 days), changed boot option back to default.
4. Vola!! It boots automatically to win10 without any keypress. Tested it with many starts to confirm the same.
5. Re-enabled hibernate option using CMD and later selected Fast Startup.
6. System booted normally, without the need for any keypress.

I do not know exactly whether such steps resolved the problem or what else happened, hence cannot suggest above steps.

Many thanks to all members who helped to troubleshoot problems.

 

Windows won't reset or restore, Automatic repair loop

Hi Bruno,

When the Automatic repair fails, we can suggest using the command prompt from Windows 10 Boot Options menu to run bootrec commands to fix the files the Auto Repair couldn't. Here are the steps:

• On the windows Recovery Option, choose Troubleshoot >
  Advanced Options.
• Select Command Prompt.
• Enter the following commands in the Command Prompt:

• bootrec.exe /rebuildbcd
• bootrec.exe /fixmbr
• bootrec.exe /fixboot

Once the repair is done, restart your PC and check if the issue is resolved. Let us know the outcome, so we could provide further assistance as necessary.

We'll keep an eye out to your response.
