Windows 10: Cannot enter safe mode

Hi, My Asus laptop is stuck in a startup repair loop while trying to fix error 0x80070091, I've tried following things:
Use this guide: Startup Repair Infinite Loop Recovery - Windows 7 Help Forums
Use the option 'reset this pc' and tried to use 'system recovery' but all to no avail.
While in this startup repair loop it also seems impossible to enter safe mode. (I've tried to enter safe mode pressing F5 from the startup settings screen). I guess using the tweaking repair program will solve this error (0x80070091) but obviously I have to enter safe mode first. Any suggestions?


Thx!

cannot enter safe mode

Hi Wind,

A third-party program conflict can be the reason for this error.
To help us determine the appropriate troubleshooting steps

• What is the build and version of Windows that you’re using? To check, type
  winver in the Search box, select the resulting command and send us a screenshot of the information window.
• Are you receiving the error code during startup or when running an application?
• Have you made any recent changes before you encountered this issue?
• What troubleshooting steps have you done so far to resolve your concern?

In the meantime, we recommend that you check this article on how to perform

We look forward to your response.

 

cannot enter safe mode

I had a problem with my computer with code error 0xc000034.. i try to check on my files using safe mode but each and every time i try to go into safe mode and it fail. it keep on restart and will not show this pic

 

Check and see if there is anything in this Tutorial that can help you. Boot into Safe Mode on Windows 10 - Windows 10 Performance Maintenance Tutorials

You may be able to boot into the USB/DVD you installed Windows from and select 'Repair this Computer' from the third screen (I believe). It should take you into the repair options.

 

It is not easy to fix that system restore error. If you read the first 3 or 4 pages or so of this thread
System Restore fails: AppxStaging %ProgramFiles%\WindowsApp 0x80070091 - - Windows 10 Forums

you will eventually see that someone solved this by by renaming (or deleting) the WindowsApps folder.

Turning to what you are attempting to do - you are trying to restore the backup copy of the registry.
You could do that by first booting from an external bootable medium.

You could use Kyhi's bootable DVD/flash drive, which you can find at the top of the Software and Apps section of this forum, which gives you a Windows style environment.

Or you could boot from a Win 10 install medium, and use the command prompt.

 

I had the same exact problem, where I had created a restore point and when my PC did mess up, I couldn't use the System Recovery because of that exact error. I was frustrated and wanted to boot into safemode. I got into the blue screen before the safemode, and I couldn't enter it because of BSOD.

So as a last resort, I just reset my PC and chose the selection to "Keep my files".

The other way to get to the advanced options screen is just to reboot again and again while it's still booting up. Until the Windows display "Preparing Automatic Startup Repair"

 

Thanks for all the help so far *Smile

A) Type the command below into the command prompt, press Enter, and go to step 9 below.

iDamn:

I've tried this several times. It's takes a while and when finished Windows will tell me that 'there was a problem with resetting Windows'.

Every time I start my PC, Windows automatically prepares for automatic startup repair but without success

 

What I think you should be aiming for is to restore the backup copy of your registry, having booted using a bootable medium such as Kyhi's disk, as I mentioned above.

Please see attached- if you use Kyhi's disk you can use file explorer.
Be very careful about the drive letter you are working with - it may not be C:

However, whatever you've tried to do mean time (resetting etc) might have invalidated this. I don't know.

Of course, if you had been using disk imaging routinely, you could have restored a previously created disk image. We strongly recommend this approach.

 

I kept running into all sorts of problems trying to fix the problem so I just did a clean install. All good now!

Thanks for all the help! *Smile
