This powerful tool provides a Boot Repair feature that can help you fix and rebuild BCD directly. It is easier and faster and has multiple systems supported, which is quite convenient, unlike using commands.

If your computer has trouble booting up because of incorrect, changed, corrupted, or damaged system files, SFC (System File Checker) can replace them with the cached version of the files. The SFC Scan command can automatically recognize and modify the system files and settings, including DLL files, to deal with the issue.

Step 1. Open Command Prompt from Windows recovery mode.
Step 2. Type chkdsk c: /f /r in the command prompt and hit "Enter".
Step 4. Check the C drive where the user's startup folders are usually located.

If you have hard drive issues or other hardware problems that prevent you from booting normally, this tool can be especially useful. The Startup Repair tool examines and repairs startup files, the Windows boot manager, faulty system files, missing drivers, dual-boot configurations, incorrectly configured settings, etc.
It can also generate logs of its outcomes, which might be helpful in troubleshooting Windows startup failure issues.

Step 5. Navigate to the "Save & Exit" page and press "Enter".
Boot your computer again. Check if it is normal now.

Step 1. Enter the Command prompt from advanced options.
Step 2. Type in diskpart in Command Prompt and hit "Enter".
Step 3. Type list disk and hit "Enter".

Step 14. Type exit when the process is complete, and then restart your computer.
Your UEFI boot should be fixed now. Go and boot up Windows 10 on your computer again.
Patching a Windows update or installing a new driver might be the reason why Windows 10 fails to boot. You can use CMD to restore your Windows 10 system to an earlier version. However, documents, emails, music, or personal files cannot be recovered in this way.

Step 2. Choose "Troubleshoot".
Step 3. Select "Advanced options > See more recovery options > Startup Settings > Restart". Then, hit "6" or "F6" to boot into the safe mode with CMD.
Step 4. Open CMD as an administrator. Type rstrui.exe and hit "Enter".
Step 5. Then, you will see the restore point settings. You can choose "Recommended restore" or "Choose a different restore point". Then, follow the onscreen guide to finish the rest steps.
