Abstract
A method for blocking an external boot device, a non-transient computer readable storage medium, and a computer are provided. The method includes: executing BIOS program code in a POST process, where the program code includes a BIOS setup menu, which includes a boot device option; hiding device information of an external boot device in the boot device option when determining that the external boot device is classified as a restricted device; displaying a boot device menu when determining that received input information is consistent with a piece of hot key information, where the boot device menu includes the device information of the external boot device; displaying a password input window when determining that the external boot device corresponding to received selection information is classified as the restricted device; and reading the external boot device to execute operating system program code when determining that received password information matches a preset password.
