Bootable DVD from ISO Image

[gg_3000]

Guys, I have an ISO Image of a Bootable Vista DVD.. I'm able to mount it and view its contents.. After viewing the contents i'm able to confirm that its a bootable image..

When i open the ISO file in WinRAR, I only find a readme text file which says
This disc contains a "UDF" file system and requires an operating system
that supports the ISO-13346 "UDF" file system specification.

So, now how do i burn this image onto a DVD such that its Bootable! I use Nero Premium 7.5.. Should i just burn this ISO file as a Data DVD or shud i burn it as a bootable DVD?

you need to burn it as an image..
in nero there would be a option.. "Burn image to Disc" or something like it
use that option

form nero select option "burn image". it will open box that show only supported image file. browze where you have store image. select and burn it. if the image is bootable, then it will be bootable DVD.

Winrar shows that message cos you are trying to open it as an ISO image whereas it is in UDF format.
