I am beginning to understand that this was for for booting off a live cd, which does not really interest me much. However, I am trying to make a multiboot installer DVD with Customized XPSP3 and Ubuntu and a few other goodies... i made a great menu, integrated Windows XP and other things..... I have modified my initrd.gz file correct however I am still getting an ``image checksum error, sorry...``. this error occurs within the img boot file that comes with Ubuntu as I load it. Anyone have any experience with this endeavor cheers, rave
