How to remove the unwanted entries from the boot menu?
I guess I've got more than one ubuntu installation (either two or three) along with a windows 7 installation. Each of the ubuntu installations also list something extra (maybe like a safe mode?) within grub.
Firstly, how do I remove the ubuntu installations I don't use? (how do I first identify the one I do use? I log into it after booting it, but how do I delete the others)
Also, how do I leave just a Windows 7 option and an Ubuntu option?
