Hi!
Struggling here with a vyos PXE install for an Equinix bare-metal server.
I was successfully able to build the iso and setup an ipxe server to host it.
Booting up the Equinix host works, it drops me into the expected live terminal, and I complete the install as seen below:

vyos@router01:~$ reboot
Are you sure you want to reboot this system? [y/N] y
But it hangs after reboot, getting stuck at the grub boot options.
Ive tried installing on a single disk, and allowing it to setup raid, and two different ipxe servers with (1.4 and 1.3), I still get stuck at this point.
Please how can I fix this?
Its kind of urgent, and Ive been stuck here for nearly two weeks 
I have to add I wouldnt mind paid support to get this done, but I am still waiting for feedback.
