CTRL-x does not boot the system?

[尚涛]

grub-devel:

   In grub 2 at boot time,I want to change some  parameters of one system to boot,I pressed  'e'  to edit it . When I had finished ,I pressed CTRL-x  to boot,but nothing happens,why?

   I install FC2 on my hard disk (/dev/hda3), after I build a new kernel and pass "root=/dev/hda3  ro" to it ,it could not boot,when I pass "root=LABEL=/ ro" to it ,it boot  sucessfully,but why?

   How to  get update-grub script(it can generate grub.cfg automatically)?
