Hello I had my unattend all working fine and then today, i added a line to my cmd file that runs after windows is installed (cmd basically tells pc to install office) That is all i changed - then i made an ISO with cdimage (checked all settings are ok) and then fired it up with MSVirutal PC but now i am getting the CDBOOT : Couldnt Find NTLDR file. But i havent changed anything !! I thought this was a bit weird - had a looka round the forum - but before i do anything i wanted to make sure it was something simple ? It is 1.4gb ISO file. A previous iso i used and still works is 1.4gb excact size. Whats reccommend to fix this ? BTW it is not multi boot - just win xp pro
