if i use the split option to split the image to 2 cd's can i still install vista?? how will it work it will ask me to insert the second cd??

yes if you split it up then it will ask you for the second cd

When does it ask for cd2 ?

During the extraction process.

are u sure?

I can confirm this. I once made a vista dvd setup over 2 dvds, which had all languages. It worked.

It took 8 days to make the image. Over a million files processed each time for adding a language, i couldnt count any more after adding a few languages. It was a lot of files.

So you mean that you could install it with 2 DVDs asking for the 2nd automatically during installation
