Tom proposed the following answer:
You can indeed start with the 'fix mbr' thing but i doubt it will have
any effect.  As it is the easiest thing to try it might well be worth a
go, just on the off chance :)  From inside ubuntu just go up to the top
taskbar and click on

Applications - Accessories - Terminal

and into the terminal/command window/console type

sudo grub

it asks for your normal user password (a LiveCd session probably wouldn't), it doesn't mean your SuperUser/Root password - just the normal one you login with ;)  Note that while a lot of other distros also have the "sudo" command there are also many that don't, particularly the tinier distros.  For them you have to use "su" which does ask for your SuperUser/Root password

Anyway, "sudo grub" gives you a non-linux command-line - notice the change?  Now onto the grub (GRand Unified Boot-loader) command-line type

root (hd1,0)

setup (hd0)

quit

the "quit" puts you back onto the linux command-line and in Ubuntu you
could reboot from here by typing

sudo reboot

on either command-line in any version of linux or grub you can ask for a
quick cheat-sheet about a command by typing " --help" or " -h" after a
command.  For example try

sudo -h

shutdown -h

Anyway, good luck with this!

Tom :)
