I need some help here with burning udf file via nero. I am here trying to install Windows Vista on my XP system. Now here I a having the iso file of vista which is udf format. I tried to burn that using nero but when I boot my system from that the setup did not appeared on the screen. I want to create a bootable disc here by which I can simply run the setup and install vista on my pc. Can anyone guide me here to fix the issue that I am facing. I hope there will be some option available.
