>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
here is my "ls -l /mnt/gentoo/boot" output:
Code:

System.map-2.6.11-gentoo-r4
boot
grub

after i umount /mnt/gentoo/proc /mnt/gentoo/boot /mnt/gentoo and "reboot", it didn't even show boot table, just "grub" command screen,

fdisk shows your root file system to be on /dev/hda5 and swap being on /dev/hda6, yet both your fstab and your grub.conf have the root file system set to /dev/hda6 and swap to /dev/hda5. Fix that.
Also, you have a space after the closing parenthesis on your splashimage line in grub.conf. Get rid of it.

i typed them wrong, it should be:

/dev/hda5 linux swap
/dev/hda6 linux

here is in my grub.conf:
Code:

title=gentoo 2.6.11 dev kernel
root (hd0,2)


i thought in grub, (hd0,2) translate to (hda3) which is /boot partition in fstab, is that right?

Code:

kernel /kernel-2.6.11-gentoo-r4 root=/dev/hda6


somehoe my impression from document, this line root is pointing to "/" partition, that was why i set to /dev/hda6 which is root "/" partition in my fstab. is that right?

i am going to remove the space after spash closing parenthesis. thanks for the help, appreciate it.

i fixed the space after splash line.

now it still didn't load boot table, it showed "grub" command screen again.

grub>root
(hd0,2): filesystem type is ext2fs, partition type 0x83

what does it mean?

Don't yell at me for asking this, but I have to make sure - are you 100% positive that you've installed the grub loader on the correct hard drive, and are booting from the correct hard drive? *ducks to avoid brick*
What happens if, at the grub prompt, you manually type in the commands you had in your grub.conf? I.e., type
Code:
root (hd0,2)
kernel /kernel-2.6.11-gentoo-r4 root=/dev/hda6
boot


On a sidenote: You mentioned you had typed the contents of the files incoprrectly. You shouldn't type them in, you should paste them in. Also, when posting file contents and the like, make sure you place them in [code] blocks (that way it's easier to read and letters like uppercase i and lowercase L don't get confused). If you're not sure what I mean, see this: http://forums.gentoo.org/faq.php?mode=bbcode#5

i won't yell :-), what i did was:
Code:

emerge grub
nano /mnt/gentoo/boot/grub/grub.conf
grub-install --root-directory=/boot /dev/hda

pretty much as menu says.

after rebooting, on grub command screen, if i typed
Code:

grub>root (hd0,2)
filesystem type 9s ext2fs, partition type 0x83


i checked grub error list, it said that it might be menu.lst was missing, but there is a file /mnt/gentoo/boot/grub/menu.lst. also i re-run "grub-install", it didn't help to fix this problem.

yeah, now since i can't boot in that computer, i had to post from another one here :-(, sorry for any confusion. hopefully i can boot and load to gentoo soon, can't wait to see that happening.

thanks,

just trying to make grub working, just found out some valuable information on grub errors:

http://forums.gentoo.org/viewtopic-t-122656.html

it mentioned a symbolic link:

Try restoring the /boot/boot symlinkCode:
# cd /boot
# ln -s ./ boot
And then run grub-install againCode:
# grub-install --root-directory=/boot /dev/hda

currently
Code:

ls /mnt/gentoo/boot

System.map-2.6.11-gentoo-r4
boot
grub
kernel-2.6.11-gentoo-r4



here is what i did:
Code:

cd /mnt/gentoo/boot
ln -s ./ boot
ln: `boot/ .':cannot overwrite directory

where should i put the symbolic link? i do have "boot" directory under "/mnt/gentoo/boot", but it is not a symbolic link though.

thanks,

Inside /boot directory.

The commands are provided below. Note the period between "-s" and "boot" in the second command.
Code:
cd /boot
ln -s . boot

thanks for the tip,

just try to make sure i am going to do the right thing:


i currently logged in though live CD, i had to mount again:
Code:

mount /dev/hda6 /mnt/gentoo
mount /dev/hda3 /mnt/gentoo/boot


Code:

cd /boot
ls
System.map-2.6.9-gentoo-r1
boot ----> .
initrd-2.6.9-gentoo-r1
kernel-2.6.9-gentoo-r1


Code:

cd /mnt/gentoo/boot
ls

System.map-2.6.11-gentoo-r4
boot
grub
kernel-2.6.11-gentoo-r4


i guess "/boot" is directory on the live CD, right? but i should use "/mnt/gentoo/boot" since that is mounted to my partition.

Code:

cd /mnt/gentoo/boot
ln -s . boot
ln: `boot/.': cannot overwrite directory


is that right i create the soft link /mnt/gentoo/boot ? how come i got an error?

thanks,

You will need to do this from inside /boot:
Code:
rm -r boot


This happens because there is already a /boot/boot directory. But we do not want that. We want a /boot/boot symbolic link (symlink). This the ln command will help us create. But ln cannot make symlinks with the same name as a file or directory which already exists, hence the error.
