新機裝唔到windows

大家好,小弟今日o係珍寶砌左部機,其性能如下.但是,我不能安裝windows xp,部dvd rom 好似冇load過,之後就彈左咁既野出黎:Reboot and select proper boot device or insert boot media in selected boot device and press a key.
PS,我入過bios睇過hard disk 同dvd rom都偵測到,分別係SATA1 同SATA2.另外,我都入過BIOS把DVD ROM 轉到First boot.
但係我都唔知點解都係彈上面o個幾英文出黎!?我想問下咁多位c hing,究竟係咪我既方法錯左定係點?希望咁多位c hing能夠幫幫小弟!多謝!!
