Grub 2 did not install I have windows 10 intalled on another hard disk than ubuntu

[Andrew Gadd]

 Windows is on one ssd. I bought and another ssd to install ubuntu on. The windows disk is the main boot disk. I all the second to install ubuntu. Ubuntu disk is all root "/". I got an error saying Grub 2 cannot be install therefore ubuntu cannot be installed. Not sure what to do about that. Maybe reinstall ubuntu again and let the installer partition the disk its self.
