When you rename the BootMgr file in the root directory C and reboot the system what is the error message?

When you rename the BootMgr file in the root directory (C:) and reboot the system, you typically encounter an error message such as "BOOTMGR is missing. Press Ctrl+Alt+Del to restart." This occurs because the system is unable to locate the necessary boot manager file to initiate the operating system, resulting in a failure to boot. Restoring the original name of the BootMgr file is essential to resolve this issue.
