        Really great. It now takes two seconds to render the boot menu

          You dont need grub when you use efi. Did you ever try without?

            Never bothered, since it was working fine until I upgraded to Kubuntu 12.10beta. That installed GRUB2 and made a mess, but I didn't have time to look into it yet.

              And your system uses uefi? You mean it updated from grub 1.99 to 2.00 i think?

                Yes and yes.

                  Ubuntu only displays the menu if you have multiple operating systems. It's no different then how it used to be.

                  The switch from GRUB to GRUB2 happened with Ubuntu 9.10. The difference between 1.99 and 2.00 is a few bug fixes, features and that is is now no longer considered beta.

                    GRUB has been slow to load for me since around 10.04, and only in Ubuntu and derivatives. It's speedy for every other distro. You wouldn't think that a bootloader would need lots of distro-specific patches but it seems like they must add them.

                      randomizer: it may relate to theming. grub2 seems considerably slower to render when themed on some hardware, compared to when un-themed.

                        The theme is really nothing but a purple background. I would hope that this wouldn't be too taxing on the system

                        This has me wondering what precisely we are all referring to when talking about how long it takes to render. Are we talking about the time between when the bootloader screen first appears until it has fully rendered or the time between a completed POST sequence and when it has fully rendered? The delay I'm referring to is mostly between the end of the POST and when the bootloader menu first appears, which is a couple of seconds. This delay is much shorter with other distros.

                          So it's baked into Ubuntu kernels now? Must investigate. Since I don't multiboot, I'd love to purge GRUB completely.

                            You can still multiboot if your motherboard allows you to have a boot menu (probably does). You just create more entries to it.

                              Yeah, both my ThinkPads have a crappy boot manager menu, which basically just lists whatever it sees in Bootnnnn NVRAM variables. Right now, my one-and-only entry, called "ubuntu," points to \EFI\ubuntu\grubx64.efi. EFI boot appears to allow me to skip the irrelevant GRUB stuff and directly boot-load the kernel. Just need to spend a couple hours learning how to stitch it all together.
