We have been trying an unattended install of XP PRO, I used slipstream method to upgrade to SP1 then created an ISO as stated on this site. The problem is I'm getting a strange error. I should excuse myself if this has been talked about before but alas I'm new here! Anyway the CD boots ok but I get this "Please place the manufacurers XP CD in drive A:" well that's about as close as I remember but it's real close to a quote. I put in the manufacturers CD and away it goes, what's up with that. I can't find any doc's talking about it but lots of jokes! Anybody feel like enlightening me on this? Of course thanks in advance....
