Linux Mint Forums

It's possible that grub is trying to boot to the hdd that the os is not installed.
This happened to me last week.
Did you disconnect one of them before the install and reconnect it after ?

I had the same thing happen and that same message when I was helping someone install Mint 4.0

After the second reboot everything was and still is stable and boots into Mint. I thought this was a rather strange behavior.
