How do you unlock NTLDR?

NTLDR, or NT Loader, is a critical component of Windows operating systems used for booting. If you're facing issues with NTLDR being locked or missing, you can unlock it by using a Windows installation or recovery disk. Boot from the disk, access the Command Prompt, and use commands like fixmbr and fixboot to repair the boot sector. Additionally, ensure your hard drive is configured correctly in BiOS and that the NTLDR file is present in the root directory of the system drive.
