Since this started right after something was accidentally deleted from the registry, the first thing I would try is System Restore.

From the Recovery screen, go to:

Troubleshoot > Advanced options > System Restore. Choose a restore point from before the registry change.

If there is no restore point, or System Restore fails, try: Troubleshoot > Reset this PC > Keep my files

If you are given the choice, I would use Cloud download rather than Local reinstall, since we do not know exactly what was deleted or damaged.

A reset should hopefully rebuild Windows and the registry, but there is no guarantee it will work if the recovery environment itself was also damaged.

If Reset this PC also fails, the next step would be to create a Windows 10 installation USB from another computer and reinstall Windows.

I would not start running "bootrec" or "chkdsk" commands recommended by the AI answer unless the Recovery screen is showing a specific boot, BCD, or disk-related error. Those commands do not restore registry entries that were deleted.

Hello the reset and everything has failed, so my final choice is the USB windows 10 installation, would you mind guiding me through the steps of how to do that? Which USB device would I need for an 100w Gen 3 Laptop (Lenovo) - Type 82J0. And would this installation work if I do it using an HP laptop that has windows 11 installed? Thank you,

Yes, you can use the Windows 11 computer to download the installation media to a USB flash drive.

The following steps should be done on your Win11 computer.

Download the Windows Media Creation Tool from Microsoft's official website. https://www.microsoft.com/software-download/windows10

Run the tool and select "Create installation media for another PC."

Choose your language, edition, and architecture (32 or 64-bit) and select "Next."

Choose "USB flash drive" as the media to use for the installation and select "Next."

Connect a USB flash drive with at least 8 GB of free space to your computer.

Select the USB flash drive you want to use, and then select "Next."

The tool will then download the required files and create the installation media.

=====================================================

Now these steps will be done on your problematic computer:

Go to the computer's BIOS boot menu to have it boot from the USB drive.

Follow the on-screen instructions to install Windows 10, making sure to choose "Custom install" and select the option to delete all existing partitions.

Once the installation is complete, you'll have a clean installation of Windows 10 on your computer.

That's the goal, and it should be, unless you have other undisclosed problems about this computer that led you to try making registry changes. As long as hardware issue is not out there, clean install should overcome any software related issue.

I hope so, because I only deleted the Microsoft folder in error due to trying to free up storage space on the laptop.
