Ubuntu 10 install problem maybe the hard disk has installed windows 7

　　on my computer, there is install error occurs when install the ubuntu 10 release version. The problem is that it cannot find the root file system(cannot find the driver?!).

   it is very strange and i have checked the disk and install disk without any errors. Even if I replaced with new hard disk,also it cannot install error. However when i the boot with the live cd and click "Install Ubuntu 10.04 LTS" it can find the hard disk and partition.

 Because the hard disk before installed windows 7, I suspect windows 7 has done some with the hard disk. In addition, I have formatted the hard disk with low level format. it is very strange, it wasted my long time and effort.

   Lucky is that after replacing new hard disk and boot with live cd and then install the ubuntu 10, it is successful.

 

  Another thing is Ubuntu 10 is very good and beautiful.The theme color has some like mac color(purple background image). In addition, it has some transparent window and other effects. Fan!!!
