# Generate Linux boot images

Linux boot images are generated using a similar process as Windows PE boot images.  Select the appropriate boot image in the boot images list and choose either **Generate** or **Regenerate** to update the boot image.  (Note that with Linux boot images there is no difference between these two actions; both completely regenerate the Linux boot image each time they are executed.)

While there are the same content items available in the Linux boot image properties, only one is presently used:

* **Certificates**.  One or more root certificates (typically from an internal PKI) can be placed in a folder and uploaded to DeployR as a content item with an **Other** purpose. Select this content item, and **Generate** the boot image to add those files.

{% hint style="info" %}
Note: The Linux boot image generation process requires installing the Windows Subsystem for Linux (WSL), which requires hardware-assisted virtualization (for physical machines) or nested virtualization support (for virtual machines).  This will be automatically configured when needed.

Due to limitations in WSL that prevent access from a "Local System" account, the DeployR service will leverage a scheduled task running as the server's logged on user to complete the Linux boot image generation process.

Also, it is not presently possible to generate an ARM64 Linux boot image from from an x64 Windows environment.
