change the bold letters to

you missed 1

or you can use
Code:
root=UUID=85c0da58-8bd1-4697-ab40-4f5be817d137

thanks for you warmhearted replay.

but the error still exited.

Quote:

root=/dev/sda1

or you can use

root=UUID=85c0da58-8bd1-4697-ab40-4f5be817d137
ls -l dev
I have: sda,sda1,sda2.
----how to affirm which dev the grub used to boot?

I try them all and set the root=UUID...,
but the error report same message.

Is there still some way that I can try?

sda is the entire hard drive, sda1 is a partition on it, sda2 is another partition on it. Fedora usually uses a /boot partition plus a root partition with LVM. Do you also have a swap partitition. Can you post the output of "fdisk -l" command showing your partition information?

Did you create your initrd.img file to include lvm support? Otherwise, you won't be able to mount your root partition during boot.

thanks for your replay.

But I cant find the "LVM" option in "Multiple devices driver suport(RAID and LVM)" menu during execute "make menuconfig".

my kernel version is 2.6.30.3.

"LVM" option isnt support new kernel, is it?

How can I support the "LVM" option?

How did you make your initrd-<version>.img (ex. initrd-2.6.30.3.img) file?

Compile your kernel the same way you did previous. Then place LVM support through the initrd.img file using mkinitrd.
Look at the man page for more details.

mkinitrd
-c clear exisitng initrd tree
-k kernel-version to use
-m modules to load
-L add LVM support
-f root partition filesystem
-r root partition
-o filename of initrd

mkinitrd -c -k 2.6.29.6-smp -m ext4 -L -f ext4 -r /dev/sda2 -o /boot/initrd.new.img
