Recently had a PC go down that was dual booting ubuntu14 and WIN 7. I did not build or setup this PC. It had three drives:

  1. 1TB SSD
  2. 160GB HDD
  3. 2TB HDD

On start up received this message: Error: no such device: ... Entering grub rescue...

Found that a 2TB HDD had stop spinning. Replaced with 500GB SSD. Still receiving error. Still receiving error. I am guessing that ubuntu was stored on that 2TB HDD and the drive that had WIN 7 on it is on the other the SSD. Because in grub rescue I input and receive:

grub rescue>ls
(hd0) (hd0,msdos2) (hd0,msdos1) (hd1) (hd1,msdos1) (hd2)

grub rescue>ls (hd0)

(hd0): Filesystem is unknown.

...and the same for the rest of the partitions

I made a USB boot repair dive and ran the report given here: http://paste.ubuntu.com/25027438/

I only see WIN 7 on in the OS listing on line 232. So I guess I need to reinstall ubuntu on another drive?

Yes, Ubuntu was stored on a different dive, the 2TB HDD. So the best thing to do was to reinstall Ubuntu 16.04.2 on the new SSD along with Windows 10. As user: oldfred mention in the comments of the question. I had to install both OS in UEFI for them to work properly with this MSI 970A-G43 PLUS mobo. Because otherwise it would boot into Windows 10 and not Grub for OS selection.
