Bootable Vista DVD X64

I’ve done it in the past but for some reason now, I can’t make another bootable DVD. All you have to do is burn the iso to the dvd and that’s all right? For some reason I think I’m missing a step. Please help!
Answer #1
Mount The ISO With Daemon Tools Then Write Copy DVD. choose Destination drive (which you mount your ISO)
And Put a Blank DVD on your Source Drive . then burn.
Answer #2
I use PowerISO and its real lite-weight, only 1.5 MB
I can burn data
I can burn disk images
I can burn bootable disks
I can extract files from images
I can mount images on Virtual Drive
It is simple, yet versatile. It’s my Swiss knife!
Answer #3
Try ImgBurn. It always worked for me for burning bootable ISO’s.
