I changed the first boot device to Cd rom but when the computer rebooted I pressed the space bar to boot from the CD I got the following messages
1.start the computer with CD rom support
2.start the computer without CD rom support

when i tried to run the setup from there I got the message "this program can not be run in DOS"
