new install., grub can't find kernel image

Hello everyone,

after installing arch twice with getting the same result and searching through the wikis I am posting my problem here.

I installed my system following the Beginner's Guide
so I installed Grub, having

sda1    --as the boot partition (100mb)
sda2    --as the root partition (20gb)
sda3    --as the swap (4gb)
sda4    --as the home partition(rest)

But when now I boot, the grub shel prompts up and tells me I can't boot and need to load the kernel first.
So I did:

grub > set prefix=(hd0,msdos1)/grub

Pointing grub to the boot partition (right?)

grub > insmod linux

inserting the linux mod

grub > set root=(hd0,msdos2)

pointing grub to the root directory/fs (right?)

But now it cannot find the vmlinuz image anywhere.
Not even with

grub > search --set=root --file /vmlinuz

I don't see the problem and don't see where I didn't follow the instructions.
With this config the installation should have put the kernel somewhere there, right?

Thanks in advance for your answers!

grub > set root=(hd0,2)

In Grub, partition 0 is the first partition. Partition 2 is the third partition.  Your third partition is swap.

Right. Thanks for the quick answer.

The second one actually was:

grub > set root=(hd0,msdos2)

Which was what pressing tab gave me as possibillities for partititions.

Also: shouldn't the search funktion be able to at least locate the image?

thanks

Run the iso USB, mount sda2 at /mnt and sda1 at /mnt/boot (just like you did during the install) and make sure everything installed where you think it did.

As 2ManyDogs said.

If I was you I would boot live usb and:

# mount /dev/sda2 /mnt
# mount /dev/sda1 /mnt/boot
# mount /dev/sda4 /mnt/home
# swapon /dev/sda3
# mv /mnt/etc/fstab /mnt/etc/fstab.backup
# genfstab -U -p /mnt > /mnt/etc/fstab
# arch-chroot /mnt
# mkinitcpio -p linux
# grub-mkconfig -o /boot/grub/grub.cfg
# exit
# umount -R /mnt
# reboot

You could skip that mkinitcpio part but it won't harm you.

Re: new install., grub can't find kernel image

if you just want to get it to work a nice GUI installer is evo/lution.
It lets you choose everything and IMO painless way to install.
It has gparted, sudo level terminal and TUI that is already in order so all you have to do is scroll through  and configure it, it has most popular desktops envioments and is how i installed Arch.

All the "code" is downloaded as you install so you always have the latest Arch, but that does mean you need a ethernet cable though.

Evo/Lution installs Evo/Lution. It does not install Arch Linux. Do not peddle other distros in a technical support thread. I suggest you read and follow the forum etiquette if you wish to continue posting to these forums.

Thank you for your quick reply!

System wouldn't run mkinitcpio with

unknown command: mkinitcpio

So I reinstalled with

pacstrap -i /mnt base base-devel

And it turns out just pressing enter when being asked about which depositiorys to include doesn't set the default(=all) value but

1-n

where n is the number of possible packages, does.

So it seems the whole mkinitcpio never took place in the installations before.
Maybe someone could add this hint with the depositories to the beginners guide?

Thanks!
