 Posted: Tue Feb 22, 2005 10:47 am Post subject: installing without /boot partition ... sata + grub [solved] |
 |
|
my sata drive looks like this
| Code: |
sda1 Boot Primary NTFS
sda5 Boot Logical NTFS
sda6 Boot Logical NTFS
sda7 Boot Logical Linux ext3
sda8 Logical NTFS
|
after mounting, chrooting and emerging the
necessary things genkernel says something
about not finding boot but finally in the /boot directory
there is a kernel-2.6.9
the fstab currently looks like this (and lacks of many things)
| Code: |
/dev/sda7 / ext3 noatime 0 1
none /proc proc defaults 0 0
none /dev/shm tmpfs nodevs,nosuid,noexec 0 0
|
i emerged grub-static
and grub-install /dev/sda says couldnt find device
for /boot: not found or not a block device
finally it looks to me like a crappy installation but
i dont want to reemerge all the things again (download volume  )
so is there a way to repair the installation without a /boot partition
or is there a way to downsize the ext3 partition without loosing data?

It shouldn't be a problem to go without a /boot partition. I don't know for sure if Grub parses /etc/fstab for information but I assume it does. Perhaps you have a /boot entry in /etc/fstab? If so comment it out.

nope
i dont have one
i just ignored making a boot partition and mounting a hda* to /boot as stated in the handbook
is there something else i have to tell gentoo about booting from the same partition as root??
the only explicit error i get is the grub error and if i start grub if only finds a (hd0,0)
no hd0,6 (this should be sda7, right?)
the grub.config looks like this
| Code: |
default 0
timeout 10
title=gen2
root (hd0,6)
kernel /kernel-2.6.9-gentoo root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/sda7 nofirewire
initrd /initrd-2.6.5-gentoo
title=xp
root (hd0,4)
makeactive
chainloader +1

1.
When installing your bootloader, did you remember to copy over /proc/partitions (I think) to /etc/mtab? It's mentioned in the book and very important.
2.
Your grub.conf is wrong! This is mine:
| Code: |
title=Gentoo Linux (2.6.10-gentoo-r6-conis)
root (hd0,6)
kernel (hd0,1)/kernel-2.6.10-gentoo-r6-conis ro root=/dev/hda7 idebus=33 video=vesa:ywrap,mtrr vga=0x31a
|
/dev/hda7 is my root-partition. /dev/hda2 is my boot-partition. So I had to specify (hd0,1) to force grub to look in the right partition for the kernel.
You specified the root partition, but your kernel is not installed in the root, but in /boot. So you have to specify
kernel /boot/kernel[...]
or
kernel (hd0,XYZ)/boot/kernel[...], where XYZ is your root partition.

1. yes, allready done that:
| Code: |
cp /proc/mounts /etc/mtab
|
(it is stated like this in the handbook)
2. ok, now changed the grub.conf line to
| Code: |
kernel /boot/kernel-2.6.9-gentoo....
|
but the problem is still that grub-install doesnt work
| Code: | grub-install /dev/sda
Could not find device for /boot: not found or not a block device
|
| Code: |
grub
grub root (hd0,*TAB*
|
gives out
every other number fails and i think i need (hd0,6) |

Try using (hd1,*) in the Grub config. Because the driver on the livecd is modular, any regular (non-SATA) disk will first take (hd0) and then when the SATA modules are loaded the first SATA disk is named (hd1). If you build a kernel with SATA support built-in you will need to still use (hd0,*) as partition names in the grub config file though.
Anyway, mess around a bit and see what works and what doesn't.

You always say, you type in 'grub-install /dev/sda', but the manual says you have to use an additional parameter '-root-directory=/boot'!

if i use -root-directory=/boot i get the same error only that he says:
... /boot/boot not found, is not a block device
using
| Code: |
grub
root (hd1,6)
setup (hd1)
|
worked 
i do have a second ntfs ide drive 80g for backups
but i didnt used it in any configuration files. so it might
be right that this disk takes the hd0 place because
gives out hd0 and hd1...
should have tried this earlier 
BUT
after rebooting i get a grub menu and choosing gentoo states:
| Code: |
root (hd1,6)
Error 22: No such partition
|
 ... i dont know if this problem still belongs in here... |

As per my recent post: Use hd0 in your grub.conf!
You can try it on the grub command line (highlight a line and press E to Edit it).

Moral of the story: junk grub-install, use grub!

You may want to search in the GRUB error collection topic. It is a sticky topic, one of the first topics you will see when you enter this forum (Installing Gentoo). |
