Problems solved by technology

[0005] The above method is more convenient for individuals, but for testers who often install different operating systems, the main disadvantages are: First, the system needs to be re-burned once after installing the system. If it is installed by CD, different systems will take up a lot of time. At the same time, the installation speed of the CD is relatively slow; second, if the U disk is burned and installed, repeated burning is troublesome, and the burning itself will take a certain amount of time
[0006] Although there are currently third-party software on the Internet that can boot and install multiple systems from a single flash drive / hard disk, the functions are relatively single. Some only support the installation of Windows-based operating systems, some only support Linux-based operating systems, and some only support The system installation of legacy or UEFI obviously cannot fully meet the usage requirements

Embodiment 1

[0030] The method for installing multiple operating systems on a single removable hard disk includes the following steps:

[0031] 1) Format the mobile hard disk as GPT format, and then partition. The partitions need to meet the following conditions: three fat32 partitions, one NTFS partition and one Ext4 partition. If you need to do expansion, you can divide other partitions for normal storage or maintenance The first fat32 partition is used to place the rEFInd boot program, the second fat32 partition is used to place the winpe file, the third fat32 partition is used to install grub2, the NTFS partition is used to place the decompressed files of the Windows system image, and the Ext4 partition is used for Place the image file of Linux;

[0032] 2) Set the partition type. In order to achieve UEFI and Legacy dual boot, you need to install Grub2 as the boot program, you need to set the third fat32 partition as ESP partition (that is, the partition type is EF00), and create a pro...

Embodiment 2

[0040] To expand the function of installing multiple operating systems on a single mobile hard disk in Example 1, it is first necessary to initialize the mobile hard disk to GPT format in order to support UEFI boot; divide a fat32 partition separately, and install grub2 to this partition for the purpose of passing grub2 Boot to install the linux operating system and legacy windows system; separate a fat32 partition to store a third-party UEFI boot management tool, the purpose is to guide the UEFI Winpe environment to install the UEFI Windows operating system; separate a EXT3 / EXT4 linux partition, the purpose It is used to store linux image files larger than 4GB. Since the fat32 partition format does not support a single file larger than 4GB, the linux image does not have NTFS partition format driver support by default, and the image can only be stored in the EXT3 or EXT4 partition that linux can recognize; alone Divide an NTFS partition, the purpose is to store Windows system i...

Abstract

The invention discloses a method for installing a plurality of operating systems on a single mobile hard disk. The method comprises the following steps: 1) formatting the mobile hard disk into a GPT format, and partitioning the mobile hard disk into three fat32 partitions, one NTFS partition and one Ext4 partition; 2) setting a partition type, setting the third fat32 partition into an ESP partition, creating a protective 1MB MBR partition, and setting the partition type into EF02; 3) installing Grub2; 4) installing a rEFInd bootloader and Winpe; 5) adding a configuration Grub2 menu; 6) downloading a system image file; and 7) installing. The method for installing the plurality of operating systems on the single mobile hard disk in the application has the advantages of high efficiency, universality, scalability, multi-system characteristic and the like, not only supports the installation of Linux and Windows systems, but also supports the installation of two disk format systems, and hasvery high practicability.

Description

technical field [0001] The invention belongs to the technical field of software testing, in particular to a method for installing multiple operating systems on a single mobile hard disk. Background technique [0002] At present, most of the conventional methods of installing the operating system are relatively simple, such as the traditional method of booting the installation through a CD-ROM, or by burning the system image to a USB flash drive for installation, for example: [0003] In the Chinese patent application CN201110065667.6, a method for quickly installing the linux operating system using a mobile hard disk is disclosed, making a bootable mobile hard disk, copying the linux operating system iso image to the mobile hard disk and extracting two files, vmlinuz and initrd, from The mobile hard disk can be booted to realize the installation of the linux operating system. Compared with the prior art, this method of using a mobile hard disk to quickly install the linux o...
