1. Reinstalled my Windows 10 and keep all my files, no luck.

3. Set the MBR type for your Windows 7/8/10 operating system, and then hit OK.

More advanced functions such as: Migrate OS from MBR disk to GPT SSD or HDD, Convert system disk between MBR and GPT partition styles for Windows 11 are also worth a try.

Method 3: Repair Registry Entries

This method also uses a boot disk to repair Registry Entries on the PC.

Step 1. Click Repair your computer ->Advanced Options ->Troubleshoot ->Command Prompt.

Step 2. First, we need to find our which partition holds the system registries. For that, we need to use the following commands: diskpart > list vol

Step 3. We can see the partition that saves the system registry (boot is written at the end) from the listed volumes, and then type the following command to copy the necessary registry files from the boot:

xcopy c:\windows\system32\config\regback c:\windows\system32\config

Step 4. This will prompt an overwrite question if it is to all the folders (Default, Sam, Security, Software, and system) or not with an "(Yes/No/All) question. Now type the command "A "for All and click on "Enter". This will copy all the necessary files, and you just need to restart your system now to resume as normal.

Then reboot your Windows computer to see if the problem is solved.
