I've had this problem since 12.04 was in beta: I can't trigger the display of the Grub menu when I boot off the LiveCD.
This is 64-bit 12.04 LiveCD, on a 64-bit machine in BIOS mode.
Holding down the Shift key dumps me to a "Boot:" prompt. Pressing Tab displays several options. One is "Help". That displays a list of function key options. They do not work.
Another option is "Mainmenu". Selecting that produces a complaint about a missing kernel.
Two other options are to boot the CD in Live or Live-Install mode. That is useless to me because the CD won't boot unless I can get to a Grub menu and add some kernel options.
I've been using the mini-iso, which has been problematic but at least not 100% useless.
What's going on here?
