grub, kernel problem

[Slynix]

When i boot up my fresh gentoo install. It first is black for a while then the screen becomes noisy with text saying.

Booting 'Gentoo Linux'

root hd1,0
Filesystem type unknown, partition type 0x7
kernel /bzImage root=/dev/hdb6

Error 17: Cannot mount selected partition

Press any key to continue...

my grub.conf:

Code: Select all

default 0
timeout 15
splashimage=(hd1,0)/grub/splash.xpm.gz

title=Gentoo Linux
root (hd1,0)
kernel /bzImage root=/dev/hdb6

First I believe that you should be using

root (hd0,0)

You can just type root ( and then hit tab I believe and it will show you your options. Read the info at the top when you are in grub.

Post your fdisk -l information and your fstab file.

This is a problem with GRUB, is your boot partition on your first or second hard drive, because with GRUB the first partition on the first hard drive is (hd0,0). Your boot partition could very well be (hd1,0) if it is on the first partion of your second hard drive or in /dev terms, /dev/hdb1. But I'm guessing that you probably have that part right, because your root is /dev/hdb6, so it would make sense if your boot partition was also on your second drive. Also, when you formatted your drives, did you toggle the bootable flag on your boot partition? With fdisk, you do it by typing a at the fdisk command prompt, then, when prompted, the number of your boot partition. Otherwise GRUB can't read the partition.

thx for response

I have 2 hds. /dev/hdb1 as my boot partition. It is bootable.
So hd 1,0 should be right for that shouldnt it?

K got bored so i formated some space for boot partition on the first drive and that works

Huh, whats funny is that grub itself is loaded on /dev/hdb1, so why it couldn't read it, I have no idea, unless it is loaded on the first hard drive. It has been a while since I used a second hard drive to boot from, but I think that there might be some jumpers perhaps on the drive, distinguishing it as a master or slave drive? That might prevent a BIOS from booting from the drive. But the fact that the bootloader comes up and gives you the error, tells me that is not the case. Anyway I'm just throwing things out there, see if it helps you with future installs.
