But the conventional BIOS Boot is booted by MBR (Master Boot Record, chinese), but the MBR supports only four main partitions at most and only 2T hard disks at most.

In this embodiment, the simple file transfer protocol service can provide a boot program, a system configuration file, a system kernel file, and the like required in the process of installing the operating system by the target machine.
Step 3022, sending a system configuration file acquisition request to the trivial file transfer protocol service of the mirror server to obtain a system configuration file.
Illustratively, the system configuration file may include configuration items that need to be executed when system cloning is performed.
Step 3023, obtaining an installation script from the image server.
Illustratively, the installation script, when executed, is capable of performing installation steps in a system cloning process. Alternatively, the file name of the installation script may be a combination of the mirror file name and the master. For example, if the image file name is imagename, the file name of the installation script may be imagename.
Optionally, before step 3023, or after step 3023, the method may further include: based on the bootstrap program, when a kernel configuration item and a file system configuration item are executed in the process of executing the system configuration file, sending a kernel file and file system file acquisition request to the SNTP service; and after the kernel file and the file system file are obtained, the kernel and the file system are started in the memory.
In this embodiment, after the kernel and the file system are started, the process of the operating system in steps 303 to 305 is entered.

Illustratively, the related information may be an address of the EFI system partition, boot information after the address of the EFI system partition is written into a sector, and the like.
In one embodiment, step 305 includes: judging whether an EFI system partition exists according to the current system partition state; and if the EFI system partition exists, writing the related information of the EFI system partition into an operating system boot configuration file.
For example, if it is determined that the EFI system partition does not exist according to the current system partition state, the currently performed system clone may not be the UEFI-booted operating system. The address of a Master Boot Record (MBR) may be loaded to the Boot sector to obtain Master Boot Record partition Boot information; and writing the boot information of the main boot record partition into the boot configuration file of the operating system.
In one embodiment, step 305 may comprise: loading the EFI system partition address to a boot sector to obtain EFI system partition boot information; and writing the EFI system partition boot information into the operating system boot configuration file.
Wherein the boot sector may be the first sector of the target machine. By storing the boot profile in the first sector, the boot profile may be able to be launched more quickly to transfer processor control to the operating system more quickly.
Optionally, step 305 may include: sending a network configuration script acquisition request to a network service of the mirror image server to acquire a network configuration script; and writing the related information of the EFI system partition into an operating system starting boot configuration file according to the network configuration script.
