es and grub.cfg.I don't know why:(.I remember that i have done the same thing 
some weeks ago and it worked well.But now it can't work.And now i use "bootice" 
which is a windows partition tool to install the grub,this time no matter how i 
change the sdb1 or sdb2,it can also read the two partitions ,but when run the 
"normal",it tells me that "grub_real_boot_time" not found :( Oh i really don't 
know how to deal with it.

You're sending to wrong mailing list. This ML is only for bugs.
Also I heavily recommend to split your message into paragraphs and
invest some time in formatting and putting most important things first.
Your message as-is is very difficult to read. As a matter of fact I
stopped reading after 2 lines.
