An example of solving the "exiting intel boot agent" problem during system startup

To install a system for an old desktop, a hard disk and an optical drive are inserted on a cable. As a result, the system cannot be started from the optical drive normally. Observe and find that:

On the same cord, you need to set the hard disk jumper to master, and the optical drive jumper to slave to show the difference.

 

After installing the system, remove the optical drive and restart the system. A series of "Intel boot agent" prompts are displayed, and the system cannot be accessed. Check that:

The patch cord is still caused by the exception that only one hard disk is inserted on a cable. Do not set this hard disk as a master or slave. Place the Jumper in a meaningless position and the system starts normally.
