so, Just chroot to mountpoint:

chroot /mounted/path /bin/bash and then .. mkinitrd (see man page for documentation)

A bit hard to say. Try chrooting into environment and rebuilding initrd?

<snip>I am thinking of putting the CentOS iso out and then booting the VM into it just to poke around the file system. Otherwise my other option is to just clone a twin VM on another server and then just change the networking IPs/hostname. Anybody have any other ideas as to how to debug this problem?
So I booted off the CentOS-7-x86_64-DVD-1511.iso and everything looks just fine:

So the CentOS DVD iso in linux rescue mode shows that everything is there and can be mounted. I guess that means somehow either grub itself is corrupted or one of the boot images. So is there a way for me to generate a new initrd while booted in linux resuce mode or will re-installing grub help? How would I attempt re-installing grub while booted in linux rescue mode?
