Linux – A start job is running for dev-md2.device

I was following steps to setup a machine for virtualization and then ran into the following problem.

When rebooting after the installing it wants to boot into the 3.x kernel which I guess is needed for QEMU since that was the kernel the RPM installed.

What I get on bootup:

Will boot find on this kernel:

4.4.30-mod-std-ipv6-64 #9 SMP Tue Nov 1 17:58:26 CET 2016 x86_64 x86_64 x86_64 GNU/Linux

But when I try to boot to this kernel I keep getting the error and shown above.

CentOS Linux (3.10.0-514.16.1.el7.x86_64) 7 (Core)
