Repair Boot loader - CentOS 7

Hi there, I am an experienced Linux administrator. I have great understanding about grub boot loader and I can assist you with recovery from grub rescue screen. Relevant Skills and Experience I have already completed a boot fix related project.

I have a CentOS 7 VM that is having issues booting. When it turns on, it goes to grub rescue> I have tried following a few guides to recovering it, but no go. Looking for someone to spend no more than 10-15 minutes trying to recover the machine. I can rebuild it, but thought I'd see if the community can help out first. Teamviewer required to access this machine. $20 project price, if you can recover the machine. 20-minute time limit.
