How-to: Copy PXE kernel and installer from ISO image or download it

[gulden]

Summary

This article describes where you find the Linux kernel and the initrd.gz for PXE boot of UCS. You need both files to remotely install UCS from a PXE server. This article doesn’t describe how to set up a PXE server.

This article describes how you copy the files from a UCS ISO image.

Prerequisite

You must have downloaded the UCS ISO image. For download, visit Download - Use Core Edition for Free. This how-to assumes that you save the ISO image with the filename UCS-amd64.iso.

Copy the files

To copy the Linux kernel and the initial RAM disk initrd.gz, use the following steps:

0. If the mount target directory /media/cdrom0 doesn’t exist on your system, you need to create it first:4.

   sudo mkdir -p /media/cdrom0
   

1. Mount the ISO image.

   sudo mount -o loop,ro /path/to/UCS-amd64.iso /media/cdrom0
   

2. Copy the Linux kernel to the target directory. The target directory depends on the setup of your PXE boot server and where it requires the files to locate.

   sudo install -m644 /media/cdromß/netboot/linux "$TARGET_PATH"
   

3. Copy the initial RAM disk:

   sudo install -m644 /media/cdrom0/netboot/initrd.gz "$TARGET_PATH"
   

4. Unmount the ISO image:

   sudo umount /media/cdrom0
