my notebook can't boot the dvd-com and show that nonwmulation booting,how can i solve it???

应该是启动顺序错误。，
在BIOS中将第一启动改为硬盘。

can you describe more concretely? when you start your notebook and there is an dvd-disk in the dvd-rom. if the DVD-disk include autorun info and the boot order is dvd-rom , it will be boot from the dvd-rom.
