I pretty much followed flyakite's tutorial to make a custom one. After a bit of work, I finally got a boot disk working. Now my only issue is that I'm not sure how to get a unattended installation work on multi boot dvd. Anyone care to help?

First read this http://flyakite.msfnhosting.com/unattended.htm
and this http://unattended.msfn.org/beginner/winnt_sif.htm.

After that, if you don't understand something ask here.

I probably should have read that part of the guide
