building linuxcnc-dev on ubuntu 16.04 preempt-rt kernel

Definitely a quad core.

Having a hard time selecting the new kernel, can someone fill me in on where advanced options---> select new kernel is?

i forgot how to set up grub but u can try this:
askubuntu.com/questions/82140/how-can-i-...older-kernel-version

the easiest way is press shift while booting

Running into no such file or directory errors with dkph check builddeps, ./configure-with and ./autogen is this as a result of the wrong kernel?

Pressing shift while booting didn't do anything, I appreciate it though!

you can check what kernel you are using in terminal by command: uname-r .
