how did you burn the ISO? I use active iso burner, where you can download

. Then try burning it. Make sure the speed is at 12x or 4x or 6x or 24x. That should work. If you want to still split the cd's into 5, which I would not want to do, it would be better to do the DVD, but if you want to, click
here. You will see like 5 cd pictures and download all of them. Then burn them to CD-R discs with Active ISO burner. And there you go. Make sure they will work with your computer, like don't get x64/x86 (64 bit) instead of x86 (32-bit) or whatever.
