We do not have a feature like fixed boot order.
Hello, I have an issue with a Dell R640 on UEFI. I set PXE boot on 1st place in boot order, and once installed a ubuntu linux (or other), the boot order change and the boot on disk go first (with ubuntu). I see other issue about that topic, but no solution.. - Here the same questions on the french forum, but answered is provided in private - Here someone fixed it with cctk, but it's not available on linux..   What are my options ??
