None of Ubuntu 6.06 and 7.04 can not list out the partitions. I googled and found someone else said he solved the problem by using 易我分區醫生.Before I tried it I backed up my computer. I did not format all the harddrive to install Ubuntu and Windows xp because I have installed many softwares for windows xp, and I did not want to do them again. 使用易我分區醫生.先備份分區表,然后整理分區表. Ubuntu 還是不僅不能識別出多個分區,連硬盤也識別不出了.
我用易我分區醫生又恢復分區.. Good news is that the computer was totally as the same as it was before I used 易我分區醫生. 我使用 acronis 刪掉了D, E, F 分區. Ubuntu 這次能夠識別出分區了,終于不用重裝windows 把 ubuntu 安裝成功了.
