This is my first post. I would like to say that over the last two weeks we have gathered enough info from this board to get what we needed to create our first corporate unattended CD. So thanks to everyone for continued unattended install expertise & comunity support. So naturally, our next step is making a 2GB multi-boot UDF (USB Flash Device) due to storage limitations. We have poured over the forums here and have discovered a cumulative, difinitive answer that sums up the (lack of) bootability for UDF from another source here: http://www.codi-inc.com/shop/thefactsbehindbootability.htm We have also contacted the USB Mass Storage working group for expectation (ETA) in adoption of the el torito standard, BIOS declaration, etc . . . for bootable UDF. Will provide feedback ASAP.
