This is how it was for years: I had Windows Vista working fine on one hard drive. I had an older Ubuntu working on another hard drive. I was able to select which hard drive to boot.
I installed Ubuntu 14.04 from a USB drive with the intention of it being a completely fresh, overwrite it all, new install on the Ubuntu hdd. It worked. It wrecked my Windows Vista mbr too.
I cannot figure out how to make the Windows Vista drive boot. How do I do it?
sudo update-grub
in a terminal? – Kev Inski Jan 14 '16 at 19:44
