Need help with UEFI PXE Boot

[Vasco_Reis_Silva]

So, I've successfully configured BIOS PXE Boot to serve Ubuntu and Clonezilla live images over my network, however, I'm struggling with UEFI boot.

I'm using an OpenWRT router for DHCP, TFPT, NFS and all the setup, using syslinux pxelinux.0 and other necessary files, but I can't seem to find the correct files and code in dnsmasq to boot in UEFI.

The code syntax in OpenWRT is the following:


option tftp_root '/mnt/sdb1/PXEboot'
option dhcp_boot 'pxelinux.0'

I've tried using examples such as this (https://wiki.kubuntu.org/UEFI/SecureBoot-PXE-IPv6) with no sucess.

Any ideas?

Thank you!

Thread moved to installation and upgrades so you can get the help you need.

Do not know anything about network booting.

But multiple users with UEFI have not had correct UEFI boot and UEFI went to next boot in UEFI boot menu and that was PXE boot.
My UEFI has network boot option.
