Hi, I created the DVD as flyakite described. Everything worked at the beginning, but now the ISO image seems corrupted ; not readable by WinISO, and Virtual PC says that the "CD image is not valid, it must be greater than 2Mb and a multiple of 2K". In this case, even if I burn the image or bypass the error message of VirtualPC (by editing the .vmc file), the DVD boots, but all windows fail installing ; for example, XP and 2K editions break with a blue screen after the licence agreement. Can anybody help me ? I tried to remake the DVD step by step on a new folder, from scratch, but it failed. If I leave only the 2K+XP editions, it works, but if I add ME or 95 it crashed !?! I also tried to remove the -o option of CDIMAGE.EXE, without success
