I was trying to do a "clean boot" by changing these configurations, according to an online tutorial
Yeah, I truly regretted it.Messing around inside the "System Configuration" window without knowing for sure what you're doing can result in a non-functioning computer - as you've discovered.
Unless someone else here has a simple solution for your problem, it's my guess you'll need to reinstall Windows 10.
Thank you, but the system restore does not work. I will reinstall the system instead.You can give this a try however before doing anything, I would pull the drive and connect it to a working system. Make sure you have a current backup of work files, data, etc. Next you can give the instructions below a try;
If your PC won't start and you haven't created a recovery drive, download installation media and use it to restore from a system restore point or reset your PC.
- On a working PC, go to the Microsoft software download website.
- Download the Windows 10 media creation tool and then run it.
- Select Create installation media for another PC.
- Choose a language, edition, and architecture (64-bit or 32-bit).
- Follow the steps to create installation media, and then select Finish.
- Connect the installation media you created to your nonfunctional PC, and then turn it on.
- On the initial setup screen, enter your language and other preferences, and then select Next. If you don't see the setup screen, your PC might not be set up to boot from a drive. Check your PC manufacturer's website for info on how to change your PC's boot order, and then try again.
- Select Repair your computer.
- On the Choose an option screen, select Troubleshoot. From there, you can:
- Restore from a system restore point by selecting Advanced options > System Restore. This will remove recently installed apps, drivers, and updates that might be causing your PC problems. Restoring from a restore point won't affect your personal files.
