A technician receives a Windows 10 computer that fails to boot and displays the message "Operating system not found." After starting Windows Recovery Environment (WinRE) and opening Command Prompt, which command should the technician run to rebuild the Boot Configuration Data (BCD) store and restore the operating system's boot loader?
The bootrec /rebuildbcd command scans all disks for Windows installations that are not currently in the BCD store and lets the technician add them. Rebuilding the BCD recreates the boot loader information that Windows needs to start, resolving errors such as "Operating system not found." Other commands shown are useful for different repairs: sfc /scannow checks system files from within Windows, chkdsk /r scans the disk for bad sectors, and bootrec /fixmbr only rewrites the master boot record but does not rebuild the BCD.
