I write the following command but it does not work.
"(chroot) livecd/#grub-install /dev/hda"
It says that "bash: grub-install: command not found"

I do as it is described in the following instruction:

"http://www.gentoo.org/doc/sv/handbook/h ... #doc_chap3"

How can i get it work?

------------------------------------
The partitions are as follows:

/dev/sda1 = boot
/dev/sda2 = swap
/dev/sda3 = root
-------------------------------------------
The "/boot/grub/grub.conf" is as follows:

default 0
timeout 10
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title Gentoo Linux 2.6.36-r5
root (hd0,0)
kernel /boot/kernel-amd64-2.6.36-gentoo-r5 root=/dev/sda3
title Gentoo Linux 2.6.36-gentoo-r5
root (hd0,0)
kernel /boot/kernel-2.6.36-gentoo-r5 root=/dev/sda3 init=/bin/bb
---------------------------

Try running this.

Code: Select all

grub-install /dev/sda

if that fails, then try the alternative manual install.

I got the same result!

In which directory should i run the command "grub-install /dev/sda"?
I am thinking about we use the command emerge for installing. Is that why the system can not find the comman grub-install?

If it says grub-install command not found, then it's not installed yet.
Install via:

Code: Select all

# emerge grub

Then run the command with /dev/sda again.

The same result again!
"bash:grub-install: No such file or directory"

the commands i run are as following:

(chroot) livecd /#emerge grub (It works!)

(chroot) livecd /#grub-install --no-floppy /dev/sda
bash:grub-install: No such file or directory

(chroot) livecd /#grub-install /dev/sda
bash:grub-install: No such file or directory

Ok, two questions:

are you using amd64?

if yes, are you using a non-multilib profile? if you are, then you need grub-static.
if you disabled IA-32 emulation in your kernel, then you need to use lilo.

if you answer to the previous questions are no, then try the alternative config.
like so: (copied from the handbook)

# grub --no-floppy
grub> root (hd0,0) (Specify where your /boot partition resides)
grub> setup (hd0) (Install GRUB in the MBR)
grub> quit (Exit the GRUB shell)

Thanks! Now i can boot without the CD. When it boots i can see "grub>". But how can i get a grafic interface? I dont know how i should use the "grub>".
Is it possible to get a grafical intercase like Ubuntu in Gentoo Linux?

Gub should look like it does in Ubuntu, minus the Ubuntu specific image.
The instructions I think you need to follow are these:

Alternativ: Konfigurera GRUB manuellt

make sure that you remember this bit:

Code: Select all

cp /proc/mounts /etc/mtab

If you did, then I am out of ideas. You might need to wait for someone who is better acquainted with grub, or try lilio.
