on booting my vm I get grub> prompt instead of menu

[John Covici]

Hi.  I am a newbie with grub, so please bear with me on this.

I have a vm at linode -- I don't know if that makes any difference,
but I thought to mention it.  Now in this vm, I have installed grub on
/dev/sda and while doing this /dev/sda1 was mounted on /boot.
grub-mkconfig was successful.  /dev/sda2 contains a number of lvm
volumes one of which is the root volume specified in the kernel.  What
happens is when I boot up the system, I have to access the serial
console which I can do to see what is happening and I get just a grub>
prompt.  Now if I type exit, it says booting from hard disk and I get
the menu and things boot normally.

Can someone help me figure out why this is happening and how to fix?
I am using Debian 8 on that vm.  Let me know if you need more information.

Thanks in advance for any suggestions.
