Manjaro+Windows10 Dual System Installation

Preparation#

Hard Drive: Samsung 970 Evo 512G, Zhi Titanium 1T.

Plan#

	Windows	Manjaro
Samsung 500G	200G (C:/)	300G (/)
Zhi Titanium 1T	300G (D:/)	700G (/home)

In the Linux system, the root directory (excluding the home directory) is generally not too large, and most of the data generated by software is stored in the ~ directory.
The Windows system disk needs to be allocated larger, as the virtual memory used by Windows during operation needs to occupy space on the system disk, and the default location for users can only be on the C drive.

Manjaro Installation#

Tips:

The latest version of Windows has solved the issue of damaging Linux grub, so there is no requirement for the installation order of the two systems.
Full disk encryption in Linux will prevent arbitrary changes to partitions.

Download the appropriate Manjaro image#

Download the latest version of the image from the Manjaro official website. There are three desktop versions available: KDE, Xfce, and GNOME.
I personally use KDE.
Afterwards, you also need to choose the image version: regular edition, minimal edition, minimal LTS edition. The regular edition comes with pre-installed software (including Steam), while the minimal and LTS editions only have necessary software pre-installed.

Manjaro Partitioning#

Select custom partitioning.
Create a 300M partition with the flag set to "boot", and the partition format as ext4.
Create a 300G partition mounted as "/", and the partition format as ext4.
Create a 700G partition mounted as "/home", and the partition format as ext4.
Leave the rest of the space empty.

It is recommended not to choose disk encryption during the installation process, as it may affect future modifications to Linux partitions, although it can indeed provide increased security.

Initial Configuration of Manjaro#

Network Card

Newer versions of network cards may not have drivers included in the image, so you need to connect to the internet via Ethernet and install them through the settings. If the wireless network card is not recognized in the settings, you may need to seek help from the network card manufacturer's website.
Graphics Card

Generally, there should not be any issues with graphics card drivers. If there are any issues, refer to the above point.
Screen Brightness Not Remembered

Refer to my other blog post for a solution.
Configure Software Source Mirrors

It is recommended not to add the Arch CN mirror source

Windows Installation#

Tips:
It is recommended to download the installation image in Manjaro. When accessing the Microsoft website from Linux, you can obtain the direct download link for the corresponding version image. However, when accessing the website from Windows, you can only download the Windows Upgrade Assistant, and it is strongly discouraged to use images provided by so-called third-party download sites.

Create a Bootable USB Drive with the Installation Image#

There are two methods: using PE (Preinstallation Environment) or burning the ISO to a USB drive.

Using PE#

It is recommended to use Ventoy.
Official Chinese Documentation

Burning the ISO#

Insert the USB drive.
Switch to root privileges and run the following command:
```
 dd if=windows.iso of=/dev/sdb bs=1024k status=progress
```
if: the location of the image file

of: the target device for burning

bs: the number of bytes read at a time

status: display progress

Boot from the USB Drive#

Insert the USB drive.

Using Ventoy PE#

Disable Secure Boot in the BIOS and set the USB drive as the first boot option.
Restart the computer.
Use the up and down keys to select the loaded image.
Press Enter to start the Windows installation.

Using the ISO#

Disable Secure Boot in the BIOS and set the USB drive as the first boot option.
Restart the computer.
Start the Windows installation.

Issues to Note#

It is best to perform operations related to Linux partition sizes in a Linux Live CD environment. Using Windows partitioning software directly may cause serious problems.
However, the reverse is generally not a problem.
When switching between the dual systems, the system time needs to be adjusted for either Windows or Linux due to differences in how the systems obtain the time.
