I have used rsync the data in ext3fs.img to a new hard drive, and find data is right but I can't boot from the new drive.

I'm using this tool and testing now. I think it will solve my problems. BTW, the script 'livecd-iso-disk' use a 'strange' way to set MBR: cat mbr.bin > /dev/sda. I'm now sure this way could work. I use the lastest version script to copy content on /dev/sda, and it boot failed (seems like finding some usb device?). This is not a strange way to do this at all. It is a trivial way to copy the boot record to the first sector of the hard drive, /dev/sda as opposed to a partition such as /dev/sda1. There are other methods that would accomplish the same thing such as dd if=mbr.bin of=/dev/sda.  This is so very easy because in Unix/Linux, "everything is a file," including hard drives and partitions on a hard drive.

I'm not really following you.  You have a livecd you are booting from and wanting to install it to a hard drive?  That's a typical install scenario.  If your livecd is built correctly and you have a functioning anaconda installer on it you can run, it should just automatically install the bootloader.  I've been building remixes since Fedora 9 or so (currently doing F17, F18, and F19) and I haven't had any problems with that. If you want to manually install grub2, you can run grub2-install /dev/{devicename}.  That assumes you have a working grub2 environment. If I'm nowhere close to answering your questions... please explain a little more what the problem is.
