..

Minor correction (having just tried it here):  once you see the GRUB (boot) menu,
hit the letter e to edit the first entry, then scroll to the "kernel" line,
and hit the letter e again to edit that line.  It should put you at the end of the
line, where you can just type a space and then acpi_use_timer_override and then
hit enter to finish the (temporary) edit.  Then hit b for boot.
