I installed Ubuntu 14.04 on what used to be Ubuntu 12.04. I am dual booting with Windows 8.1. I haven't been able to access Ubuntu 12.04 since Windows 8.1 did some updates a few weeks back.
GRUB shows up and I can't see Windows 8.1. How can I add Windows 8 using Boot Repair?
I figured out how to install boot-repair in Ubuntu 14.04 by doing this workaround.
Most important thing: How can I add Windows 8.1 to the GRUB menu using Boot Repair?
