I have an extremely weird issue on my bootcamp disk. I try to boot my bootcamp disk by choosing start up disk in system preferences. Nonetheless, the bootcamp disk is gone. I cant see the bootcamp disk in the list. I can choose only OSX or network startup. So, I recycle the power and hold option key to start up. This time, I can choose Windows and boot the Windows without any problem. Then, I go to bootcamp tool and surprisingly, both OSX and Windows are in the list. I choose the OSX and hope that bootcamp disk will show up in the list. Nonetheless, it didnt show up when I boot from OSX. In addition, I also tried to boot up from OSX CD. I still can see both OSX and Windows in that list. But, I encounter the same situation. Bootcamp is still missing in that list of start up disks. Does anyone have this problem before? Any idea is appreciated. Thank you.
