Hey!

I've just gone through the install manual on the gentoo website and have gotten the same error as Biz...

Code:

fsck.ext3:No such file or directory while trying to open /dev/ROOT
/dev/ROOT:

The superblock could not be read... blah blah

fdisk -l

Code:

/dev/hda1       1       5         40131        83     Linux
/dev/hda2       6       68        506047+      82     Linux Swap
/dev/hda3       69     3648       3648         83     Linux

/etc/fstab

Code:

shm              /dev/shm          tmpfs         nodev,nosuid,noexec       0 0
/dev/hda1        /boot             ext2          defaults,noatime             1 2
/dev/hda2        none              swap          sw                              0 0
/dev/hda3        /                 ext3          noatime                         0 1

/dev/cdrom       /mnt/cdrom        auto         noatime                        0 1

cat grub.conf

Code:

default 0
timeout 30

splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title Gentoo
root(hd0,0)
kernel /boot/kernel-genkernel-x86-2.6.25-gentoo-r7 root=/dev/ram0 init=linuxrc ramdisk=8192 real_root=/dev/hda3 udev
initrd /boot/initramfs-genkernel-x86-2.6.25-gentoo-r7

Can't see the above being incorrect, copied the man totally apart from the sda/kernel version.

It looks to me like you did not edit your fstab correctly.

What part of it is incorrect?

**gruven** · 09-01-2008

The error you are getting does not match up with your fstab. The error says "/dev/ROOT" and your fstab says "/dev/hda3".

/dev/ROOT is in the default fstab, so I would be checking that out again and making sure that it is correct.

But then again, it could have something to do with genkernel as I have never used that. I always just do my own configs and compile my own.

Also, depending on your kernel, your hard drives should be sd instead of hd because of the new drivers.

You can always load the livecd and change the files and reboot.
