I've slipstreamed my windows 2000 disc with service pack 4, but the install cd is the upgrade. Most of the machines I delpoy this on work fine, but on some it asks me to insert the Service Pack 4 CD at the install screen. I've noticed this only happens on the same machines where I actually have to put in my Win98 cd first, then put the 2000 cd back in. Any ideas on why this is happening? Is it because I'm using the upgrade and not the full. (don't have much choice, as our open licenses are for the upgrade). Or did I make my bootable CD incorrcectly? Any insight into this is appreciated. Thank you.
