Could you try this:
Yes you should click on the link and ignore all the commands that start with #
they are just comments.
Make sure you write down the correct command, in firefox press control and + to make the characters bigger.
Could you write down any response you get after typing the commands?
#this could give you something like (hd0,2) use it for the next commands
search (hd0,2)/boot/vmlin(press tab)
#this should give you a number of options of kernels to choose, choose one
#you need to know what partition your root system is on (what is / )
#you might guess /dev/sda2 means first disk, second partition
linux /boot/vmlinuz-2.6.24-26-generic root=/dev/sda3 ro single
＃now choose initrd pressing tab will give you a list of what's in /boot
# use the same version number as kernel
search (hd0,2)/boot/init(press tab)
