Abstract

The embodiment of the present invention discloses an information processing method and an electronic device. The method includes: installing a first operating system; acquiring a storage path of a boot code of the first operating system and a system name of the first operating system; According to the storage path and the system name, a boot variable is generated; in the first sector of the first storage medium storing the boot code, the boot variable is stored in a reserved byte of a storage protection boot record.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to an information processing method and a storage device. Background technique [0002] Some operating systems (such as the Unified Extensible Firmware Interface (UEFI) operating system) will generate a UEFI boot variable in the UEFI flash memory flash to record the storage path of the boot program given by the UEFI operating system after the installation is complete. The UEFI boot variable also records the name of the operating system. [0003] Since the UEFI boot variable is stored in the UEFI flash, if the storage medium storing the operating system code and the boot code is moved to another electronic device (such as electronic device A), the UEFI flash of electronic device A will not The UEFI boot variable is not stored, so the boot code of the UEFI operating system cannot be found to boot the UEFI operating system. Contents of the invention [0004] In view of...
