Did you run

indynet's advice looks logical, however it still does not seem to fix me.

Here is my sequence of commands (to set up grub):

1) emerge grub
2) nano -w /boot/grub/grub.conf
default 0
timeout 30
title=Gentoo Linux
root (hd0,0)
kernel /boot/kernel-2.6.12-gentoo-r10 root=/dev/hda3
3) cp /proc/mounts /etc/mtab
4) grub-install /dev/hda
5) reboot

perhaps my /etc/fstab is incorrect?:
/dev/hda1 /boot ext2 defaults 1 2
/dev/hda2 none swap sw 0 0
/dev/hda3 / ext3 defaults 0 1
proc /proc proc defaults 0 0
shm /dev/shm tmpfs nodev,noduid,noexec $

What exactly is an "error 2" anyways?

indynet - thanks for the info on what the Error 2 is, now I just have to fix it (somehow?).

I noticed when I run grub-install that I receive multiple errors:
end_request: I/O error, dev fd0, sector 0
then
mount: /dev/fd0 is not a valid block device

Does this have something to do with my "Error 2" problem?

I am out of ideas, as I have followed the install manual very closely and tried everyone's suggestions......

aneeshm,

what disk have you configured in the BIOS to boot your system? How did you install GRUB?

You have two options to solve this issue.
1. To boot with the live-cd, mount the partitions, chroot and run passwd to set the root's password.
2. Edit the Gentoo entry on the GRUB menu, press 'e' and add to the end of the kernel line the following init=/bin/bash. That should allow you to start the system. Then you should run passwd to set the root's password.

So, I have a 120GB SATA HDD, dualbooting gentoo and winsuxxXP. Currently I'm using ugly stupid lilo because GRUB does'nt work :evil:

Tried everything but all I get is "GRUB Hard Disk error", googled it, searced it, only thing i found that this means "grub can't determine disk size or geometry" :?:

But what the heck can I do to get grub working?

I tried the new graphical installer and it appeared to me that there is no place to specify where to install the boot loader (Grub), and I quit it. I need to install Grub in /dev/hda2, please tell me what's the easiest way to do this. Perhaps I should first choose not to install it at all and then boot from the LiveCD again and somehow emerge grub and set it up manually?

elephant,

If you install grub on /dev/hda2, you will need another bootloader to start grub, since the BIOS will only ever load the MBR.
You should use the manual install method.

Yeah I need to keep the windowz boot loader in the MBR for some programs we have to use at uni etc.
Ok thanks for helping me clear this.

elephant,

Grub can start windows. You can do it the other way round too but thats much harder.

hi guys,

i have just installed a gentoo system on my pc with an nf2 board and 2 sata drives.
everything worked as usual, but on my first reboot i got something like this:

jmbsvicetto · Posted: Sat Mar 18, 2006 7:40 pm Post subject:

Hi.

Please post your grub.conf, the output of fdisk -l and the contents of /boot - don't forget to mount it first.

Hi.

Have you tried changing in the BIOS the disk from auto settings to manual settings?
If that doesn't work, please post the exact error message.

In that case, have you tried the following:

homry · Posted: Sun Mar 19, 2006 12:00 am Post subject:

ok,

for some reason /dev/sda3 does not get mounted on /boot during booting. that is why i did not see anything in that directory. when i was in the live-cd enviroment i mounted sda3 manually to /boot, but still could not see any content. something went wrong there for sure, my fault.

now i booted the system (not with the live-cd), manually mounted sda3 to /boot, copied bzImage to it with the nvidia-sata-driver in it (also with the siliconImage driver) and rebooted the system. the error message from above remains and /dev/sda3 still does not get mounted to /boot while booting. but the error message from above is related to sdb3 (which should be an empty, freshly formatted data partition with ext3-fs) NOT to sda3. maybe 2 things are going wrong at the same time. my fstab looks like this:

Keruskerfuerst · Posted: Sun Mar 19, 2006 9:43 am Post subject:

/dev/sda3 /boot ext2 noauto,noatime 1 2

change noauto to defaults and

copy the conents of the not mounted /boot partition to /mnt,
mount /dev/sda3
and copy /mnt to /boot.

and change in /boot/grub/menu.lst

kernel /boot/kernel

to

kernel (hd0,1)/kernel...............
