kubuntu bootloader dual-boot setup

[overdank]

Been trying to get dual boot setup with kubunto working. I had to do a clean install of windows as the second OS because it wasnt working properly. Each of them work when they are set to priorty in the UEFI settings now. If kubuntu is set to priority and i select windows as the boot option in the bootloader i get an error message and im not sure how to fix it.

With the new Windows install, the boot info will have changed, but Kubuntu's grub boot-loader config hasn't been told about it. Fortunately, it should be an easy fix:

sudo update-grub
