It is not that you are so stupid it is that sometimes, the poster will leave out a pertinent piece of advice/ information necessary to carry out the task. In this case, looks like we forgot to tell you to change the file attribute.
If you're running XP, go to Run, Search and type in "boot.ini" w/ out the quotes. When windows returns the search result look in the right pane and Right Clikc on the file. Choose Properties. Uncheck the box that says "Read Only", Click OK. Now Right click again on that file, and click on "Open With...". Choose Notepad in the list of choices. Edit the file as directed above. Click on File > Save. Then exit Notepad. Go back to the search results, and R-click on the boot.ini file again. Click on Properties. This time recheck the box that says "Read Only".
