I have some troubles that I cannot fix it now, my computer could not boot into Windows 10, and I tried everything that might fix it:

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

This error message can be caused by compromised file system integrity or by corrupted or missing Binary Coded Decimal (BCD). To solve this problem, you can choose from 3 solutions, including rebuild BCD, rebuild MBR, and repair registry entries. For more details, please refer to:

▶ Method 1. Rebuild BCD with Windows installation Disc

● bcdedit /export c:\bcdbackup (export bcd file to get bcd file copy)
● attrib c:\boot\bcd -h -r -s (the attrib command will help you to remove the hidden, read-only, and system attributes from the bcd file)
● ren c:\boot\bcd bcd.old (now the BCD store is renamed, you should be able to rebuild it)
● bootrec /rebuildbcd

5. After running all these commands, you will find these words like this:

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.
