I had Windows 10 and Ubuntu 16.04 both working with Grub.
After Windows update, I got a screen saying there is no OS installed. I tried Boot-Repair using Boot-Repair-Disk and used recommended repair. Boot-Repair finished and I got a message to restart. After restart, I still get a "No OS" in opening screen.
Any chance I won't have to reinstall OS?
PC is Dell Inspiron 15 3000 series
