Background technology
GPT (globally unique identifier's partition table) zoned format is a kind of subregion framework of novel management hard disk.Compared with " host sectors is recorded " (MBR) partition method, GPT has more advantage, because it allows each disk to have nearly 128 subregions, support the volume size up to 18 peta-bytes, primary partition table and backup disk partition table is allowed to be used for redundancy, also support unique disk and partition id (GUID, globally unique identifier).
Although GPT subregion has support that hard-disk capacity is large, but the hard disk with this subregion does not start by traditional MBR mode, that is BIOS (Basic Input or Output System (BIOS)) does not directly load Boot Loader (os starting loader) program by reading MBR, and must carry out load operation system by so-called Boot Loader mirror image under loading UEFI (unified Extensible Firmware Interface) environment.This Starting mode just creates the problem that hard disk cannot use on multiple mainboard, and a GPT hard disk can only start on that block mainboard of its installation system, and reason is the Boot Loader mirror image deposit position that other mainboard does not know this block hard disk.
In prior art, develop by the built-in EFI-Shell (Extensible Firmware Interface shell) of BIOS, found the solution of the Boot Loader of operating system in hard disk in the mode of order line.But command line mode more complicated, for general user, does not have professional knowledge related to this cannot apply it, moreover consider from user-friendly target, we do not wish to be started the operating system by this way yet.
In addition, also there is following solution in prior art: in Windows system, in NVRAM (non-volatile random access memory), add new startupoptions by BCDEdit order.But, this scheme needs one piece of GPT hard disk that can start, and need the order inputting more complicated to realize, in addition, also staff is needed to be familiar with principle and the form of GPT subregion, if do not have professional equipment and professional knowledge, staff is difficult to solve technical matters as discussed above.
Summary of the invention
For this reason, the invention provides a kind of hard disk startup method, comprise the following steps: there is the subregion of FAT32 in basic input-output system BIOS identification hard disk after, is globally unique identifier partition table GPT subregion by subregion sign; Pre-service is carried out to the startupoptions being masked as GPT subregion; Pretreated startupoptions is kept in non-volatile random access memory NVRAM; And BIOS finds the mirror image of os starting loader Boot Loader, thus carry out hard disk startup.
Pre-service comprises further: the device path of newly-built media; The subtype of device path is set to file type and default file name; And device path is attached on the device path of the startupoptions being masked as GPT subregion.
The path of the Boot Loader under GPT subregion framework is :/EFI/BOOT/BOOTX64.efi or/EFI/Microsoft/BootMgr.efi.
