John Thanks for reply! I will answer the questions in a moment, but, have made some progress. I went back into nlite session and burned to a CD-RW (rather than the DVD-RW used previously). When I start up the PC it does, indeed, recognise it and starts the Windows install process! Now, the questions you asked..... The DVD was created by using the 'Burn Direct' option in nlite Yes, those are all the files on the DVD The size of all the files in the directory nlite created/modified is 339 MB (356,315,136 bytes), made up of 3,571 files in 206 folders I have attached several files. The older pair are for when I tried to burn the DVD-RW and the later 2 are when I burned the CD-RW. LAST_SESSION__205601.02_12.22.50_.INI LAST_SESSION.INI
