When bootrec fits
bootrec is more closely associated with classic recovery actions such as fixing the MBR, writing boot sectors, and scanning or rebuilding boot configuration data.
When bcdboot fits
bcdboot is commonly used to copy fresh boot files from an installed Windows directory and rebuild essential boot configuration on the target system partition.
How to choose
Use the error and the current boot state to decide. If the boot files themselves are missing or damaged, bcdboot is often the stronger recovery step.
