Hi, i've installed gentoo 2007 but...i've a boot error and i don't find any doc about it.

I've one hd p-ata master so it's hda !

my partitions are:

/boot /dev/hda1
/swap /dev/hda2
/ /dev/hda3

I've installed grub with this grub.conf:

default 0
timeout 10

title=Gentoo
root (hd0,0)
kernel /boot/kernel root=/dev/hda3

In grub:

root (hd0,0)
setup (hd0)

All it's ok!

So...i reboot and....my pc is blocked with:

GRUB Loading stage1.5Read Error

There is not the error number ! It's blocked. I've reinstalled gentoo 5 times!! but...i don't resolve

help please!

baldomax,

Are you sure your kernel's name in /boot is "kernel". It may be something else if you used genkernel to install it. If you are unsure, enter

# ls -l /boot

to see what your kernel is named.

Hi,

May you post your /etc/fstab. Check if your boot partition is mounted all the time. Mount it and reinstall grub.

Did you completely and succesfully install GRUB into your /boot partition? Seems that GRUB is unable to locate its stage2 components in _its_ root filesystem. Try to boot from the CD, chroot into your Gentoo environment as you did during the install and do the following:

I've deleted noauto but i've the same error.

grub-install --recheck /dev/hda1 :

(fd0) /dev/fd0
(hd0) /dev/hda

So...it seem correct.

i can modify grub.conf with

I've also tried with

Hi, may I ask you to use google; e.g. keyword: GRUB Loading stage1.5Read Error

That error is usually caused by the stage 2 files (anything under /boot/grub) not being readable by GRUB. This could be because you don't have a

I was going to post about it but was busy with other things. Anyway, last weekend I installed Gentoo, dual boot with other Linux distros in my new AMD64 machine and did a grub-install --no-floppy /dev/hdb. Yet, it seems to be unbootable since grub appeared to have not been installed - I only got my old grub from the other O/S. When I tried to boot Gentoo by adding the portion relevant to Gentoo in the current grub, I received a kernel panic message:
