Ok, i made my first multiboot dvd a week ago following the tutorial, and it's working awesome. I had some problems with *.DAT (boot) files. What happend? When i extracted the files from installation cd's by using IsoBuster, i could not open it in hex editor on my windows machine, was getting some rundll error every time i tried to open the file. I solved that problem with linux. I copied the files on the floppy, edited them by using hex editor on my linux machine, did not get any errors there, when opening the files. Now I have some questions about aditional software. Here's what happend... when i add aditional folder with extra software (drivers, programs, codecs....) and make an image with cdimage.exe, the only windows i can install from dvd is 98SE. The ones that are based on NT File System... well it all goes fine until i have to press F8 (the part where i say do I or do I not agree with Microsoft agreement). When installation comes to that part i get the blue error screen. When i remove the folder with aditional software, i make an image, and it all works great. Someone knows why this happens? Thanks for any help.
