I recently created a Windows XP CD using nLite, slipstreaming in various addons and setting it up to be an unattended install. But whenever I try to boot from a CD created by nLite, I get the message: "Please insert the disk labeled Microsoft Windows XP Service Pack 2 CD into drive A" The CD I'm using to get the setup files already has Service Pack 2 on it and everything. I've done some searching on the internet, and found that the problem is often caused by a missing WIN51IP.SP2 file (or win51ip.sp2 apparently capitals matter). On the CD I have, the file is there, spelled in lowercase. After applying nLite, the file becomes uppercase. I tried changing it back before making the ISO, but it didn't help. I've tried running the ISO in Microsoft Virtual PC 2004 and qemu, as well as burning the CD and trying it on my laptop. Still the same error. Does anyone have any ideas on what's wrong?
