Hi rs,

It seems from your screenshots that you have a boot partition. Thats ok, just to confirm.

You use "root=/dev/disk/....", thats also ok, but I am not very found about that.
Difficult to see if the disk you are trying to boot from is the right one.

I sugest that you (probably with a LiveCD), comment this line in "menu.lst" and add one with "kernel /boot/vmlinuz26 root=/dev/sda??"
where "??" is the partition number where your kernel is.

Or you can do it at the Grub prompt by choosing to edit line.

If at the grub prompt, try "grub> find /boot/grub/stage1", grub will search for this file and tell you the partion it is in.

yea my partition name is sda1..can i just edit the kernel from the grub from dis:

kernel /vmlinuz26 root=/dev/disk/by-uuid/0b651866-1040-4741-8aca-bfdd48e65f11 ro

to dis??:

kernel /vmlinuz26 root=/dev/sda1/by-uuid/0b651866-1040-4741-8aca-bfdd48e65f11 ro

or do i must edit dat strings on menu.lst with a live cd? cos i dont hve dat cd anymore..i could re-download it..but..i just wanna try to fix it without it..if possible..

btw when i type find /boot/grub/stage1 it says..no found ( or sumtin like dat)
but when i type find /grub/stage1 without "boot" it gives me sumtin..

so..can i just edit dat string from grub or...do i need to use the cd live?

lemme no n thnx for the answer..

The line will be:

kernel /vmlinuz26 root=/dev/sda1

just that.

but when i type find /grub/stage1 without "boot" it gives me sumtin..

The output should tell you in which partition grub finds your boot files. Whats the output ?

If your boot is in /dev/sda1, your root should be (hd0,1) not (hd0,0).

Code:
'Booting Arch'
root (hd0,0)

Can you post your menu.lst ?

Howewer, if this is a new installed system, perhaps reinstalling ?

Did this grub trouble start after some update ?

From the Grub prompt I dont think you can do it. Better use a live CD.

Or install an ext2/ext3 driver in XP (your own risk):

http://www.fs-driver.org/

so as to be able to read the Arch partition from WinBlows.

no tnx..

Your problem is that the default grub install misses /boot/ for some reason.
Edit your /boot/grub/menu.lst file to look like this:

# (0) Arch Linux
title  Arch Linux
root   (hd0,0)
kernel /boot/vmlinuz26 root=/dev/sda1 vga=791 nopat
initrd /boot/kernel26.img

From the error you posted at the top of the page the problem should be what I stated. You can easily edit the grub entry by hitting 'e' over the selected line. How about you give it a shot and let us know if it works?

You changed the last line too, correct? Also, you don't need the trailing backslash on /dev/sda1
I have no idea if that would cause the error or not though.

Did the latest kernel update fail on you or something? Grub is seeing your partition (it states the file system type), but it can't locate your kernel and initramfs...

yes

dunno..i just updated typing pacman -Syu

n then after the reboot i had dis troubles..

any other ideas to can solve dis prolem?

wut live cd? i ve an arch o my cd but its not a live..can i use any live cd like ubuntu live or sumtin? n when i will open the terminal on dat live wut i will ve to do? i mean on the menu.lst..

Yes, use a ubuntu livecd, and mount the partition where your real system is. Something like:

mount /dev/sda1 /mnt/mydisc

The mountpoint must exist, create it with 'mkdir'.

And then post your menu.lst.

Probable you had troubles while upgrading the kernel.

While you are at it, do a 'fdisk -l /dev/sda', so we can see how the drive is partitioned.

ahhh - you have a seperate boot-partition!!
I presume your root filesystem is on /dev/sda3, so your (/dev/sda1)/grub/menu.lst should be:
kernel /vmlinuz26 root=/dev/sda3 ro

Other than that - with such a small root filesystem, your /var/cache/pacman will overflow quite easily and cause problems whenever you do a pacman -Syu

neoraptor · 2008-11-03 19:34:54

You seem to be right!

I have the same issue with your proposal. I will make my root partition bigger.

How much space is required for a standard usage?

EDIT
I have done a new installation and get same issue.
I had 20Gb root partition.
After upgrading the system (pacman -Syu), I have clean the cache (pacman-Sc).
I check my disk usage and get 7.3G used.

Then I rebooted and get the same error in grub (error 15).

perbh · 2008-11-03 21:26:01

you sure it's 20 gig??
according to your 'fdisk -l /dev/sda' above - the disk is only 12-13 gigs!!
- or did you use another disk?

personally I prefer 16-20 gigs for the root filesystem, but I guess 10-12 is more than sufficient if you are clever at cleaning up cache. The last update I did on my own computer was 2.5 gigs in downloads - and its only about 2 weeks since my previous update.

perbh · 2008-11-03 21:32:01

Grrrrr - I just h-a-t-e these disk-by-uuid, disk-by-label, disk-by-whatever!!
What the heck is wrong with /dev/sd[a-z][1-12] ??

(sorry about the rant - had to vent somewhere ...)
