I have Windows 7 and Ubuntu 12.04 with grub providing dual boot. I would like to upgrade the Ubuntu via a re-installation and keep my grub so I can dual boot.
I am at the point in the installation process where I am presented with the screen:
"This computer currently has Windows 7 and Ubuntu 12.04.2 LTS".....
Am I ok selecting "Erase Ubuntu 12.04.2 LTS and reinstall"? My grub will not get deleted?
update-grub
, at which point it will see that you have windows installed, and create a new menu. You should be safe.
