BT3高手请进 小弟有问题请教

不废话 小弟直接问了 BT3装好了 选了选BackTrack 3 后 出现下列英文
Fatal error occured - BT3 data not found.
You are maybe using an unsupported boot device (e.g. SCSI or old PCMCIA).
Workaround: Copy the directory BT3 from your boot device to an IDE/SATA
disk, eg to /mnt/hda1/BT3 or C:\BT3. Then try to boot again.
Something went wrong and we can't continue. This should never happen.
Please reboot your computer with ctrl+Alt+Delete 。。。

请问是什么原因
