It isn't a real problem, but if there is a way to fix it, I would like to. I have several Ubuntu installations on one computer, but on boot and shutdown, only the primary installation that grub was installed to the MBR from has a nice resolution and boot splash. All the other installations boot splash's are a blinking cursor on a black screen, and the resolution is ugly, on boot as well as shutdown.
Why is this? and Can I make it so that my Ubuntu 12.04 have a nice boot again, like my 12.10 now does (because its grub wrote over MBR)?
