Hi, Today I added Windows Server 2003 to my Multiboot-DVD, but when i start the os in the bootmenu it comes with the error: NTDETECT failed. I already searched on the forum, but couldn't find any useable solutions. Also after I added Windows Server 2003, XP gives the same error, while XP worked perfectly before. Someone who knows a solution for this problem? Thanks, Ruud. /edit: Problem solved. I copied some files from windows 2000 boot directory and it worked. I think there was an error in my winnt.sif
