Embodiment Construction

[0010] like figure 1 Shown is a schematic diagram of the hard disk structure of the computer in the preferred embodiment of the present invention. A computer generally includes a Basic Input / Output System (BIOS, Basic Input / Output System), a hard disk 10 and a memory. Wherein, hard disk 10 is made up of many discs (platter), and each face of each disc has a read-write magnetic head (Heads), and magnetic head is numbered sequentially from 0, 1, 2; The concentric circles with a fixed value R logically form a cylinder (Cylinders) with the motor spindle as the axis, numbered from the outside to the inside with 0, 1, 2; each track on each platter is divided into Dozens of sectors (Sector), usually with a capacity of 512 bytes, are numbered from 1, 2, and 3 according to certain rules. In this way, a cylinder (Cylinders)×heads (Heads)×sector (Sector) sector is formed. These three parameters are the physical parameters of the hard disk.

Abstract

The method to switch OS by hotkey comprises: self checking by BIOS once startup; displaying all custom of default prompt information of hot key; deciding whether user presses set hot key; if yes, checking whether connects to the HD, if yes, auto modifying the HD partition table in MBR, namely modifying the partition parameter with corresponding OS; returning to the BIOS self check; loading the MBR; by the modified parameter, searching OS by HD bootstrap for startup.

Description

【Technical field】 [0001] The present invention relates to a method for starting a computer operating system, in particular to a method for quickly switching operating systems among various operating systems with hotkeys by modifying the Basic Input / Output System (BIOS) method. 【Background technique】 [0002] When a certain operating system of the computer is damaged, or when the user needs to switch from one operating system to another, it is usually necessary to run an application program installed in the computer to modify the master boot record in the hard disk , and issue a prompt message to guide the customer to perform a series of operations, thereby starting the backup system of the operating system, or switching to another operating system; the damaged operating system can also be restored through an external expansion device, or another operating system can be loaded system. For example, the invention patent of China No. 1392490 published on January 22, 2003, titl...
