To make a bootable CD using Nero it is not enough just to choose that option in the nero config tab. You also need the proper bootfiles.zip to be downloaded (bootfiles.zip), extracted and reffered. If you just let that field blank, that's the reason you overwrote the nLite boot files with none. Here is a tutorial I've tested years ago and still working: http://www.tacktech.com/display.cfm?ttid=297 As for Burning bootable Media with nLite, it only failed once for me, but then I closed, reopened the nLite, didn't load the last session (because I didn't want to touch the UA files already in the folder) and I burned again - it worked with no problem. So there are a few tips it might help: set your writer's speed to 8x (check again if you say you did so), try not to handle the drive while in process and also reduce the memory/processor loading with extra operations.
