Abstract

The invention discloses a method for realizing bi-operation system starting of terminal equipment by using a USB (universal serial bus) controller and belongs to the technical field of dual operation system starting of the user terminal equipment. The method is characterized by including on a single hard disk provided with a working area and a free area, judging whether the USB controller is inserted or not by a BIOS (bi-operation system); if yes, executing a modified guide file GRLDR in the USB controller, verifying PIN of a user, loading a secret key, guiding to enter a reserved partition, executing a decryption program to decrypt the working area, and then entering the working area; if not, guiding to enter the free area by an MBR (master boot record), executing a partition boot record (PBR), in the type of BOOTMGR, of the free area, and entering the free area. Different from other methods for realizing bi-operation system starting through double hard disks, the method has the advantages that a mode of realizing bi-operation system starting through the same hard disk and multiple partitions is used, and through an encryption mechanism of a working area operation system, safety of the working area operation system is guaranteed, cost is lowered, and efficiency is improved.

Description

technical field [0001] The invention relates to a method for using a USB controller to guide a terminal device to start dual operating systems. Two operating systems are installed on the terminal device, which are independent of each other. ) to switch between two operating systems. The first operating system supports users to browse the Internet, install and uninstall any software by themselves, and belongs to the operating system environment in the user's free zone. The user's online behavior and software installation in the second operating system and uninstallation are strictly controlled by the background server, and belong to the operating system environment of the user's work area. Considering the data security requirements of the operating system environment in the work area, the operating system environment in the work area is encrypted and protected. Background technique [0002] At present, user terminal equipment is widely used. For example, users browse the Inte...
