Install Ubuntu via iPXE for UEFI

Install Ubuntu via iPXE for UEFI:

• iPXE
• DHCP Server

First of all, let us download the needed ISO files for this project.
Ubuntu Desktop 22.04.2 LTS
Ubuntu 22.10 live server


iPXE can serve as a network boot server for both BIOS and UEFI systems. It’s open source, it can use many protocols to download the required boot files (TFTP, FTP, HTTP, HTTPS and NFS), but it needs compiling. In this case we will use a live installer on our synology virtual machine to compile iPXE and transfer it to our NAS.
Creating a iPXE shared folder:
Let’s create a shared folder to keep our iPXE boot files organized.

On your Synology, go to Control Panel and select Shared Folder.
Control Panel

Click Create and click Create Shared Folder.
Create shared folder
Fill out the name for the folder and click Next.
Shared folder creation wizard

In this case, encryption is not needed, click Next again.
On the next screen, click Next.
Confirm Settings

This is what your settings should look like. Click Next again.
In the following screen, leave the settings as is, (administrator and your own account should have read/write access). And click Apply.

Enable TFTP:
In Control Panel, go to File Services.
File Services

Go to tab Advanced, Enable TFTP Service and Click Select.
Select the Shared Folder you just created. Click Select and Apply.

Next, we are going to enable NFS. Go to tab NFS and select Enable NFS and Apply.
Enable NFS
Go back to Shared Folder in Control Panel, select your shared folder for iPXE and click Edit.
Go to tab NFS Permissions and click Create.
Create an NFS rule
In the Hostname or IP field, put an asterisk (*)
Privilege should be Read only
Select Allow connections from non-privileged ports and select Allow users to access mounted subfolders. Click Save.
Edit Shared folder iPxe
You should see something like this. Click Save again to apply the permissions on your shared folder.
Copy your Ubuntu Desktop and Ubuntu Server ISO files to the iPXE shared folder.

Select the virtual machine and click Connect. A new browser window will open and your virtual machine will show.

Installing required Dependencies for building iPXE on Ubuntu Desktop Live:
Open the terminal.
Open Terminal
$ sudo apt-add-repository universe
Add Universe Repository
Press Enter.
Press Enter
$ sudo apt install build-essential liblzma-dev isolinux git
Install essentials

Press CTRL – X, Y and enter.
Compiling iPXE for UEFI-Based Motherboards:
$ make bin-x86_64-efi/ipxe.efi EMBED=bootconfig.ipxe
make bin
The ipxe.efi firmware is being compiled. This could take a minute or two to complete.

cp bin to downloads
Open Firefox, go to the webinterface op your NAS and open File Station.
open Files in Ubuntu, navigate to the Downloads folder and drag ipxe.efi into File Station in Firefox.
Shut down the virtual machine and go back to the usual web-interface in your browser.
Put ipxe.efi in the iPXE folder we created.

Create a new folder by clicking on Create. Name the folder config (!!!all small letters!!!) and click OK.
Create a new folder in iPXE
Name the folder Config
If not installed yet, in Package Center, install Tekst Editor.
Text Editor
Once installed, open Text Editor.
Click File – New.

Choose ipxe.efi
Click Apply
Mounting the ISO files on your NAS:
Go to File Station and navigate tot he iPXE folder we created.
Right click on the ubuntu desktop and ubuntu server ISO files we copied and click Mount Virtual Drive.
Mount Virtual Drive

Make sure to select Mount automatically on startup and click on Mount.

Open Text Editor and edit boot.ipxe.
Our file should look like this:
boot.ipxe before editing
Then, we modify it like this:
boot.ipxe after editing
clearing up boot.ipxe

Set server_ip: IP-address of your NAS.
Set base: IP-address/volume pool/iPXE 
Make sure set os_name is equal to the folder name in iPXE. We use this to define the nfs-path to download the files we need to install the Operating Systems.
Example nfsroot: nfsroot=
