This doesn't seem in any way relevant to what you want to do

/boot is at ... /boot. To find out which partition it is (if any), run 
'mount'. If you find no entry, then the /boot directory is on the 
same partition as /

edit /boot/grub/grub.conf (it might be called menu.lst on Ubuntu and 
ass 'noapic' or 'noacpi' to the end of the relevant line starting 
with 'kernel'. Reboot.
