Can you clarify a bit? How did you install Ubuntu? Did you put in the CD 
while in Windows and install Ubuntu within Windows or did you reboot from 
the CD and install from the LiveCD?

That is a message of your monitor, not the computer. But when did you see 
this message? When you boot up, the first thing you see should be 
messages from the BIOS while it is checking the memory and other things. 
Then there should be a boot loader where you can select the operating 
system. That could be the Windows boot loader or the Ubuntu boot loader 
(GRUB) depending on how you installed Ubuntu. Now if you selected Ubuntu, 
it should display the Ubuntu logo and a progress bar. Finally after about 
1 minute (or even longer if you have a very slow machine) it should 
display the login screen. Now the question is which of these parts did 
you see before there was the message from your monitor?

Not me.

It may be that there is a driver problem, but I'd rather expect a 
configuration problem. If you answer the questions above to give us some 
more details someone might have a solution. It would also help if you 
tell us some details about your machine, especially the type of monitor 
and graphics card (you can probably find out from within Windows, but I 
can't help you there).

No, it can't help because Ubuntu is not a Windows program but a separate 
operating system which controls your computer while it is running. 
Therefore Windows settings don't apply.
