Cool, thx for the quick info, btw I am thinking they will be in the order that they are listed on the screen, but how screwed am I if I delete the wrong one?

The top line is:
multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Micro soft Windows XP Home Edition" /fastdetect

The next one is:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro soft Windows XP Home Edition" /fastdetect /NoExecute=OptIn

On bootup I have to choose the bottom one, so I am assuming it would be the same here.....I guess I could always change the text that is displayed just to be on the safe side.
