In some computers that also have Windows XP or Windows 7 I normally reboot the PC and from the GRUB menu select Windows if I want to boot to it or just leave it alone to start with Ubuntu. I am trying to find a way to, for example, when telling Ubuntu to restart it gives me a choice to restart with another operating system without having to be there when the grub menu appears. Like a temporary option that boots to Windows, Mac or another Linux Distro for that time. Something like a "quick OS switcher".
Is this possible?
