dr_s99,

Welcome to gentoo.

One (or more) of the filenames you have in your grub.conf does not match the filenames you have in /boot. This is normally because you have copied the handbook verbatim and file versions have changed since it was written.

As long as the names match - that can be anything you like.

Look at your kernel filename and your inird file name.

Oh. I'm going to merge this post with the grub thread, but i need to practice first, since I'm new to moderating :)

Enjoy your gentoo.

well the problem is that right now i can't get pass the grub screen,
now i even tryied to make kernel /usr/src/linux/boot/imagebz (or something like this) but when i type boot, my whole system restarts...!

How do i get pass the GRUB?

is there anyway i could get the handbook??

When you are in the grub selection screen type in C, it will take you to a console screen

Do

well, that doesn't work either...
The only folders under (hd0,0) are

lost+found
.keep
boot
grub

and when i try to make root hda3 tell it that the kernel is in /usr/...etc the system crashes as soo as i type boot!

Well therein lies the problem. Post here the grub.conf

And also, did you use genkernel or did you manually config your kernel?

Try first getting rid of the /boot part so it should look something like this.

well i got grub working,but now
i get this error

Post the previous 5 to 10 lines. You should have a "unknown block device (X,Y)" message. That usually means that you forgot to compile the driver for your storage controller in the kernel <*> and not as a module <M>. You should look at the output of lspci if you don't know what storage controller you have.

well, i don't see that error, and how can i run lspci? when i'm at boot():: ?

all i see is

>>Activating udev
>>Determining root device...
!! The root block device is unspecified or not detected
Please specify a device to boot, or "shell" for a shell...
boot() ::

If you're still using this grub.conf

well right now, form the edit part of grub... i see this commands...

root (hd0,0)
kernel /kernel-genkerne-x86-2.6.12-gentoo-r10 root=/dev/ram0 init=/linuxrc ram
initrd /initramfs-genkernel-x86-2.6.12-gentoo-r10

You're missing the real_root parameter. Without it, you can't start Gentoo. Use the following:

hey,i tried that the error i get now is

Block device /dev/hda3 is not a valid root device...
The root block device is unspecified or not detected

Now i have also tried sda3 but that doesn't work either...!

is there anyway i could get access to fstab... through the grub / shell before (ie. boot():: ) i want to make sure my fstab is correct..

or is there any way i could reinstall grub? or is there anyprogram that could fix it?

Boot with the live-cd, mount your partitions and look at /mnt/gentoo/etc/fstab and /mnt/gentoo/boot/grub/grub.conf. If you want to reinstall GRUB, chroot and run grub.

Post the exact error message, your /etc/fstab file and the output of fdisk -l. If you can, emerge parted and post the output of parted -s /dev/hda print.

Hi,

I seem to have a similar problem. After setting everything up for about 2,5 hours I came to the point to reboot my system.

After the reboot GRUB brings me the warning:
