15.04 to 15.10 upgrade grub issue

I have two disks in my PC. The primary has Windows loaded and had been running fine for a couple of years. I assume it still does, although I haven't tried it in a while.

The second drive is where Ubuntu is loaded. I chose to "deactivate" the primary drive in BIOS once Ubuntu was installed so that the PC boots into Ubuntu automatically. To run Windows, I go into BIOS and "activate" the primary drive. Everything has worked for about 6-8 months.

This morning I saw a notice asking if I wanted to upgrade from 15.04 to 15.10. I chose to do so. However, the install went smoothly until it got to grub. The line on the upgrade screen now says "setting up grub-pc (2.02-beta2-29) ..." It is hung there, probably because it cannot find my grub installation.

I don't really want to reboot the PC at this point. I'd like the upgrade to finish cleanly. How can I nudge the grub setup to the proper disk?

Any thoughts?

I don't see any way around rebooting that PC. My recommendation would be to turn that PC off and then take out the drive with linux on it, hook that drive up as a slave to another linux computer so that you can do a full data backup. Then, for the original PC, disconnect the drive with windows on it, connect the drive with linux on it as the primary and only drive, restart the computer and see if the upgrade completes as it should. If it doesn't, you can then install ubuntu 15.10 from scratch.
