Your first paragraph/post reads just fine...
I don't understand that last sentence/post at all. I appreciate that English may not be your first language, but puting a period or 2 in there and explaining what is happening might help
A few questions:
Do you have /boot on a seperate partition? (If you don't know, then you probably don't)
Can you post up your /etc/lilo.conf so we can see it's contents and give advice on what to change?
Can you also post up what this returns:
ls -lh /boot
