This page shows how to install Windows Subsystem for Linux (WSL) system on a non-system drive manually. It can work with both WSL 1 and WSL 2.

Enable Windows Subsystem for Linux system feature

Open PowerShell as Administrator and run the following command to enable WSL feature:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

Create a folder in a non-system drive

Run the following command in PowerShell to create a folder for the installation. For my environment, I will create the folder in F drive.

cd F:\mkdir WSLcd WSL

Download a Linux distro

Run the following command in PowerShell to download a distro:

Invoke-WebRequest -Uri https://aka.ms/wsl-ubuntu-1804 -OutFile Ubuntu.appx -UseBasicParsing

The following distros are available:

Unpack the downloaded distro

Run the following PowerShell commands to unpack:

move .\Ubuntu.appx .\Ubuntu.zipExpand-Archive .\Ubuntu.zip

Initialize Linux distro

In the unzipped folder, there is one executable (*.exe).

cd .\Ubuntu\ls
Directory: F:\WSL\Ubuntu

* Based on the version of Linux distro you are using, the executable name can be different.

Run the executable to initialize:

 .\ubuntu1804.exePS F:\WSL\Ubuntu> .\ubuntu1804.exe
Installing, this may take a few minutes...
Please create a default UNIX user account. The username does not need to match your Windows username.
For more information visit: https://aka.ms/wslusers
Enter new UNIX username: raymond
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
Installation successful!
To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

* You need to input a user name and password. I am using username raymond with**‘password’** as password.

Once the installation is done, you can see a new folder is created:

PS F:\WSL\Ubuntu> ls

If you install WSL from Microsoft Store, the default folder in your Windows user profile will be used:

%localappdata%\Packages

rootfs folder includes the following folders:

PS F:\WSL\Ubuntu> cd .\rootfs\
PS F:\WSL\Ubuntu\rootfs> ls
Directory: F:\WSL\Ubuntu\rootfs

These folders include all the Ubuntu folders (libs, executables, etc.).

List all the WSL installations

You can install many Linux distributions in one Windows system.

wslconfig command can be used to list all the installed distributions and set default distribution:

wslconfig
Performs administrative operations on Windows Subsystem for LinuxUsage:     /l, /list [/all] - Lists registered distributions.         /all - Optionally list all distributions, including distributions that                are currently being installed or uninstalled.     /s, /setdefault <DistributionName> - Sets the specified distribution as the default.     /u, /unregister <DistributionName> - Unregisters a distribution.

Find out all the WSL installations in your Windows system using the following command:

wslconfig /l
Windows Subsystem for Linux Distributions:
Ubuntu-18.04 (Default)

Set default distribution:

wslconfig /setdefault Ubuntu-18.04

Run the following command to start the default WSL distribution:

wsl

To uninstall a distribution, use the following command:

wslconfig /u distribution_name

Now you have a WSL installed in a non-system drive. Have fun!

I uninstalled everything then tried again and got this exception:-

indicated."
At
C:\WINDOWS\system32\WindowsPowerShell\v1.0\Modules\Microsoft.PowerShell.Archive\Microsoft.PowerShell.Archive.psm1:934

So my system is still trying to use the "C" drive, didn't get this last time but it installed correctly, just on my C drive.

Did you follow the exact steps in the guide? The error you encounter usually is caused by that fact the file to unzip us big a zip file. You can try downloading the file through browser and then unzip using GUI tools like 7zip and then follow other steps to install.

Graham access_time 2 years ago link more_vert

Doesn't work for me, still uses my SSD drive not the one I want. I've also set the system to install on my "D" drive, but always installs on "C".

Never mind I looked around some more a found a solution the kali exe is buried another layer in. So after the first extraction. You get this.

after renaming and extracting using the steps in the guide you get this.

and then moving into that folder and doing ls we see the kali.exe

Raymond access_time 3 years ago link more_vert

I’m glad you figured it out. Let me know if you encounter any other issue.

Taha C. access_time 3 years ago link more_vert

Hi I tried to install kali linux using this guide but after extracting the zip file there was no executeble in the extracted directory. Just these files

How can I install the distro from these?

Dmitry access_time 3 years ago link more_vert

The only helpful tutorial to get WSL working on Win10 after c:\Program Files\WindowsApps\ folder was broken or something (running [...]\ubuntu.exe from there resulted "File not found" error although the file was there).
Thank you!

I'm glad it helps :).

I have Ubuntu 18.04 installed and have it set as my default with wsl. I do not have the rootfs after installing it. What I have is

is the ext4.vhdx what the rootfs actually is?

I appreciate your help and the rest of everything that you posted was great. I just want to see what I messed up. XD

Although it has been a while since OPs comment, will be leaving this reply here to help out any future visitors.

This is because the article is outdated, and uses WSL1. Your Ubuntu 18.04 is probably installed with WSL2, which uses Virtual Hard Disk (.vhdx) to store your Linux files. Afaik, the way to install your WSL2 on a non system drive is to first install it on C: drive by default, then to export it to a tar file using

wsl.exe --export <DistributionName> <FileName>

This will generate a tarball of your WSL distribution (It might take a while depending on .vhdx file size). After that, you can import that distribution to any other location, including a non-system drive, like so:

wsl.exe --import <DistributionName> <InstallLocation> <FileName>
