error 15 file not found

Hi

I´m new to linux/gentoo. I've just installed gentoo on my desktop. But when I boot my computer I get error 15, file not found. I am using GRUB. I think the kernel name in Grub is wrong. How do I find the right name and how do I change it in GRUB?

TIA

when the grub menu shows up press the "c" key and you'll get the grub prompt
type "ls /boot" and you'll get a list of your installed kernels
type "kernel /boot/<any_installed_kernel_name>" and then the "boot" command
after the boot process has fineshed, mount your boot partitition and change your /boot/grub/grub.conf file with the right kernel name

Hi

pressing 'c' I get the promt, but typing 'ls' gives error 27 unrecognized command. By pressing TAB I get list of possible commands 'ls' is not there.

ops... i thought there was also a ls command...
however you can use tab completition after entering "kernel /boot/" to get a list of installed kernels

ok, I entered 'kernel /boot/' and TAB

then I get:

Possible files are: lost+found boot .keep grub

does this mean I have no kernel on HD?

(thanks for your help)

yes, i think so...
maybe you forgot to mount your boot partitition before copying the kernel image there...
i suggest you to mount a livecd and to check it out

well.. it should be somewhere. I followed the installation guide carefully, but I failed to make a note of the actual kernel name. I think the installation went ok, so the only problem should be wrong kernel path in GRUB.

I´m new to linux so I need detailed instructions...

as i said in my previous post, you should boot a livecd and mount your hd partititions.
then copy the kernel image you have compiled during the installation process (supposing you run a x86 machine, you'll find it on your root partitition as usr/src/linux/arch/i366/boot/bzImage) to your boot partitition.
modify grub/grub.conf on your boot part.
reboot...

Step-by-step instructions:

Boot your computer from the Gentoo CD
type in mount /dev/hda3 /mnt/gentoo (see Note 1)
type in mount /dev/hda1 /mnt/gentoo/boot (see Note 2)
type in cp /mnt/gentoo/usr/src/linux/arch/i386/boot/bzImage /boot/bzImage (see Note 3)
type in umount /mnt/gentoo/boot /mnt/gentoo
reboot your system (with the reboot command)

Note 1
Assuming your boot partition is /dev/hda1

Note 2
Assuming your root partition is /dev/hda3

Note 3
Assuming your kernel is called bzImage in the /boot/grub/grob.conf file.
If it was called kernel-2.6.3-gentoo-r1 the command would look like cp /mnt/gentoo/usr/src/linux/arch/i386/boot/bzImage /boot/kernel-2.6.3-gentoo-r1

I followed the advices from LeTene
when I did:

cp /mnt/gentoo/usr/src/linux/arch/i386/boot/bzImage /boot/bzImage

I got: No such file or directory

the directory /mnt/gentoo/usr/src/linux/arch/i386/boot
has following files:
Makefile bootsect.S install.sh setup.S video.S
and directories:
tools compressed

any suggestions?
