Now the system is running well.
Just yesterday, I got the 7.10 version discs from CANONICAL. However, like the 7.04 before, there are still some errors when installing. I think the problems may have some relationships with my hardware. especially the 780g chips and AMD AthlonX2 4400+. So I download the latest 8.04 from http://www.ubuntu.cn, put it on my windows C:/, and then search a grubfordos tools.It takes about 1 hour to install. The bad news is that I have chose the English language, no Chinese, that's the reason why you can see those sentences.
Anyway, system is ok now, although the screen isn't 1440*900. I will deal with it tomorrow and write a introduction.
Now, go sleep and enjoy the next 3 days.
