Appendix
Always Make Sure of the Serving File Names For example, please make sure the target file name for linux and initrd is correct. For example, the default initrd binary file name of 20.04.1 is initrd, and it is initrd.lz for 20.10. Always make sure you serve the right file names. This is a frequent troubleshooting issue. Pay attention on this detail could save a lot of your time. Booting Screenshots If your setup is correct, your grub.cfg should redirect the process to an ephemeral environment to download your target image assigned in the grub entry of grub.cfg. You will see a screen like this if you are able to access console or monitor device of your target machine: uefi-ubuntu-live-server-01-ephemeral-env-download-image|690x246 Wait a bit to complete downloading. If you see this subiquity welcome page, the installer is successfully launched via your UEFI PXE setup.
