grub-install problem [SOLVED]

Here's the error I'm getting when I run grub-install:
/dev/root.old: Not found or not a block device.

Up to this point, everything has gone fine. I'm just not sure what I did wrong to get this.

My partitions are:
/dev/hda1 - /
/dev/hda2 - swap

My grub.conf is:

Code: Select all

default 0
default 0

title=Gentoo Linux 2.6.15-r1
root (hd0,0)
kernel /boot/gentoo-2.6.15-r1 root=/dev/hda1

Any ideas?

first, you have 2 default lines. get rid of one

second, what command did you use to install grub?

it should be

Code: Select all

grub-install /dev/hda

if your hard disk is set as master

I am using grub-install /dev/hda. I'll check the default lines. I'll bet that is the problem.

now I realized what I typed... It should be:

default 0
timeout 0

I got rid of one, and it makes no difference.

Also, it seems like manually installing it works. I'm booting to find out right now...

And it worked... Interesting. I guess it's fixed, but I have no clue why.

Hm, did you follow exact steps from Gentoo Handbook?

It says:

Default: Setting up GRUB using grub-install

To install GRUB you will need to issue the grub-install command. However, grub-install won't work off-the-shelf since we are inside a chrooted environment. We need to create /etc/mtab which lists all mounted filesystems. Fortunately, there is an easy way to accomplish this - just copy over /proc/mounts to /etc/mtab, excluding the rootfs line if you haven't created a separate boot partition. The following command will work in both cases:

Code Listing 5: Creating /etc/mtab

# grep -v rootfs /proc/mounts > /etc/mtab

Now we can install GRUB using grub-install:

Code Listing 6: Running grub-install

# grub-install /dev/hda

I did follow it. I tried a manual installation, instead of the automatic grub-install, and it booted up with no problems it seems. Although I'm missing network stuff right now, but that's more minor right this second.

I had the same problem - the cause was that I forgot to copy the mount table:

Code: Select all

cp /proc/mounts /etc/mtab

Once I did that it worked like a charm.
