Currently, there are various operating systems with different functionalities on the internet, such as Windows, Unix, Linux, and Mac... ...without further ado, let's get started with the tutorial.
Dual-booting refers to installing two operating systems on different partitions of a computer, allowing the two systems to coexist without interference. The choice of system depends on system compatibility and hardware architecture. If supported, you can choose any combination like dual Windows or Windows + Linux. Generally, you need to set one OS as the default system and the other as a secondary system, with the default OS installed on the C drive and the secondary OS on any other partition. I am using Windows (Primary) + Kali Linux (Secondary).
Download the Image
To set up a dual system, you must first download the system image. Currently, the two main common image formats are ISO and Ghost.
About ISO and Ghost:
ISO is the pure version, with many settings being default, original and intact, suitable for those who require high security and prefer the original version without other software. Installation speed is slower, requiring manual driver updates and settings, and commonly used software must be installed by yourself.
Ghost is a secondary developed system, where developers can add software, modify default settings, integrate drivers, remove some features or software, optimize certain aspects of the system, and it is customizable with fast installation speeds. However, it may come with preinstalled software, potential backdoors, adware, and possible compatibility issues or bugs.
You can download either ISO or Ghost images based on your needs; the specific differences between the two formats will not be elaborated here.
Here are some download links for various Linux systems (for Windows system images, please refer to another article).

Well~, let the browser download in the background, now please look at the next step.
Set Up Partitions
This is a crucial step, so be careful during the process; don't click incorrectly, or you will regret it.
Press Win + X or right-click the Win menu to open "Disk Management."
Here, you need to create a new partition or format a partition to load the system. It's simple to do and you can find partition tutorials on Baidu. Tutorial link
https://jingyan.baidu.com/article/425e69e6bbd0c7be14fc164a.html
However, before partitioning for the system installation, you must look below!
Operating systems can only be installed on primary partitions (basic disks) formatted with NTFS.
Windows distinguishes between basic disks (primary partitions) and dynamic disks (extended partitions); basic disks are ordinary drives, while dynamic disks can be expanded and span multiple partitions. If your computer uses dynamic disks, the management interface may contain keywords like "extended partition" or "logical partition."
What is a dynamic disk? A dynamic disk can combine storage areas located in different physical locations into a new partition. "Dynamic disks" are named using "volumes," which are not limited to the 26-letter alphabet. The greatest advantage of "dynamic disks" is that they can expand disk capacity to non-adjacent disk space. Visually, the disk is a basket for storing items; a partition labeled as "basic disk" is one basket that cannot hold more than its size, while a partition labeled as "dynamic disk" is like several baskets merged together, which can hold a lot, and when capacity is insufficient, you can add more baskets to expand.
Note that basic disks can be converted to dynamic disks, whereas dynamic disks cannot be directly converted to basic disks; this conversion is not bidirectional! A hard disk can have a maximum of 4 primary partitions, and during partitioning, the size can be allocated arbitrarily. When there are 4 partitions, you can create additional partitions, but once you exceed 4 partitions, primary partition sizes cannot be adjusted. When the number of hard disk partitions exceeds 4, from the 4th partition onward, they will be dynamic disks, meaning there are only 3 basic disks, and the rest are dynamic disks. Once there are more than 4 partitions, if you attempt to adjust
a primary partition, at this point, the primary partition will convert from basic disk to dynamic disk!
At this moment, congratulations, you cannot convert dynamic disks back to basic disks without loss, and operating systems can only be installed on basic disks. You can only delete all dynamic disks by removing the "volumes" and then delete the partition to revert to basic disk, which means all partition data will be lost. If you accidentally click wrong and wish to undo, please refer to another article on the public account~~
Currently, ISO images generally come with installation tools, so there’s no need for USB drives or complicated operations. You can double-click the ISO file and click "Install System" or setup.exe to install the system as instructed; you can also extract the ISO file to the new partition before installation. If you have a .GHO-format Ghost image, you will need a one-click Ghost tool.
Of course, you can also use a USB drive created with tools like Dabi or Maotao to make a boot disk, enter the PE system, and use Ghost tools for restoration.

In fact, using Ghost is also quite simple; just choose the image and select the disk according to the instructions.
Dual System Boot
After installing the image, this step begins, allowing you to choose which system to boot into when the computer starts.
Essential software for dual booting: EasyBCD
Download link: http://www.greenxf.com/soft/14581.html
After installing the software, open "Edit Boot Entries"; if your computer already has two options, you can skip this step.
Click "Add New Entry", you can name it arbitrarily, and the drive would be where you installed the secondary system, then click "Add Entry."
Of course, you can also directly boot from the ISO image package, but the data will not be retained after shutting down, similar to a diskless system used in internet cafes.
At this point, you can shut down and restart to select the dual system!
If your main system is Windows 10, then during boot, it might
skip the selection interface directly, because Windows 10 has a fast startup feature, which keeps the system in a hibernation-like state rather than a full shutdown. You can use the iReboot function of EasyBCD to quickly switch operating systems, or you can find a way to make the computer fully shut down before rebooting.
