Hi. My friend and I just traded XP Pro for 2000 Advanced Server. I'm trying to set 2k AS on my computer I have acting as a server. Right now, it has that copy of XP Pro. I put the CD in the drive and it said something like since this is a newer version of Windows setup will be disabled. So, I restarted, with the CD in the drive. After it counts all the ram, and goes to boot, it says something like Operating System Not Found. Nothing else. I got into DOS, but for some reason it wouldn't let me access any drive other than the floppy. [I'm trying to get another boot disk, but right now am having problems with finding a good floppy]. I tried taking all CDs out, and it still says Operating System Not Found or whatever it says. I put another XP cd in, just to test it out, and it booted right into setup. My friend said I need to create a second partition, alongside XP's, and then install it on that. Well, I can't install it if I can't get into setup. Also, I have my drive full, with just 2 partitions. One, 3 GB for the OS, and the other is 114 GB for documents. Since it was just a file server I didn't think I'd need any more. What do I do now?
