Sorry, typo.

Code:
mount /dev/hda6 /boot
Ext2-fs warning: mounting unchecked fs, running e2fsck is recommended
cd /boot
cd /usr/src/linux
-/bin/bash: cd: /usr/src/linux: No such file or directory

Ok. So you seem to be missing /usr/src/linux. Please post the output of
Code:
# mount
# ls -l /usr/src

However, I still don't understand if you're able to boot into your new system and if not what error you get. If there is an error, please post the complete and precise error message.

I have to add two points: I find it very frustrating because the only way i know how to copy this information is by hand/pen. and also i cannot figure out how to leave the livecd to enter commands such as nano, the only nano command i can edit is my grub.conf, which was handy.

<what i type>

Code:
<mount>
tmpfs on /type tmpfs (rw)
/dev/cdroms/cdrom0 on /mnt/cdrom type iso9660 (rw)
/dev/loop/0 on /mnt/livecd type squashfs (ro)
proc on /proc (rw,nodiratime)
systs on /sys type eysfs (rw)
udev on /dev type tmpfs (rw,nosuid)
devpts on /dev/pts type devpts (rw)
cache dir on /mnt/livecd/lib64/splash/cache type tmpfs (rw)
tmpfs on /lib/firmware type tmpfs (rw)
tmpfs on /usr/portage type tmpfs (rw)
usb on /proc/bus/usb type usbfs (rw)
<ls -l /usr/src>
total 0[/

If you don't know how to do two things at the same time on the live-cd, you can use at least 6 VTs by pressing ALT+FN with N equal to the terminal. So for terminal 1 press ALT+F1, for terminal 2 press ALT+F2 and so on.
You should be able to use links2 with the live-cd. If you enable gpm, by selecting text with the mouse, you can paste it into another terminal by pressing the mouse middle button.
Did you run mount under your new system? It seems you runned it under the live-cd. Have you rebooted the system and attempted to start it? If so, what happens?

This is what happens, i told you earlier, but it still doesnt help, nothing is working and i dont know what to do, copying and pasting into another terminal wont help me paste it online because i cant even load up a networked environment. Im really frustrated. I cannot get gentoo working, i dont know how to restart the installation, I dont know how to format my partitions nor do i want to if the problem is easily fixed, i DONT know how to edit things in gentoo without using the livecd and when i use my livecd i dont know how to access anything else. what am i doing wrong how can i get this right?

Questions:
1. What command allows me to exit the LiveCD area when i boot up with my livecd?
2. How do i correct my problem in the above quote?
3. How do i get my system to boot up properly?

Ok, let me try to address some of your questions to help control your frustration.
Let me start with an initial note, don't reinstall your system just because you have a problem. You'll likely get it again later and will be upset by the time you've wasted.
If I understood it correctly, your first problem is that you don't know how to recreate your sytem from the live-cd. That's simple. After booting with the live-cd, you have to mount your partitions under /mnt/gentoo as you did when you installed the system, and then you have to chroot
Code:
# chroot /mnt/gentoo /bin/bash
# env-update
# source /etc/profile

When you're done, you leave the chroot with exit and you can restart your system by doing
Code:
# unmount /mnt/gentoo/boot
# unmount /mnt/gentoo/proc
# unmount /mnt/gentoo/
# reboot

For your system to be able to boot properly, you have to correct the problems with your kernel. That means recompiling it, copying it to /boot and to update GRUB. I'm convinced the error you've posted doesn't happen when you boot from your new system, but when you try to update your kernel after booting with the live-cd and having forgotten to mount the partitions. Am I right?

Well, it doesnt look like im going to get out of this situation early...

(Im using knoppix so i can copy the text straight over for you)

Code:
root@0[knoppix]# chroot /mnt/gentoo /bin/bash
chroot: cannot change root directory to /mnt/gentoo: No such file or director


This same code came up using the gentoo livecd, im running out of ideas now.

:cry:
Code:
noppix@0[knoppix]$ ls /mnt
auto  cdrom  floppy  hda1  hda5  hda6  hda8  hda9  sda1


/mnt/gentoo is disapeared, where did it go?

The knoppix live-cd does not have a /mnt/gentoo dir. You will have to create one by hand. If you don't remember the partitions you've used to install Gentoo, post the output of fdisk -l.

Like i mentioned i tried the same code in the livecd and it still didnt find /mnt/gentoo. it came up with the same that knoppix did.

Code:
root@0[knoppix]# fdisk -l

/dev/sda1   *           1          39      249572+   e  W95 FAT16 (LBA)


Now this is what i what i got when i tried to load Gentoo from grub.
Code:
Booting 'Gentoo Linux'
root (hd0,5)
Filesystem type is ext2fs, partition type 0x83
kernel /kernel-2.6.12-gentoo-rc6 root=/dev/ram0 init=/linuxxrc ramdisk=8192 real_root=/dev/hda8 udev
Error is: File not found


To this error i tried as is listed in this topic to:

Code:
mount /dev/hda6 /boot
cd /boot
ls
cd /usr/src/linux
make menuconfig
cp /usr/src/linux/arch/(insert system type)/boot/bzImage /boot


so i tried to chroot into gentoo through the live cd and i got the same output that i did in knoppix:

Code:
root@0[knoppix]# chroot /mnt/gentoo /bin/bash
chroot: cannot change root directory to /mnt/gentoo: No such file or director


I also attempted in knoppix:

Code:
root@0[Data]# mount /dev/hda6 /boot
root@0[Data]# cd /boot
root@0[boot]# cd /usr/src/linux
root@0[linux]# make menuconfig
  HOSTLD  scripts/kconfig/mconf

arch/i386/Kconfig:36: can't open file "init/Kconfig"
make[1]: *** [menuconfig] Error 1
make: *** [menuconfig] Error 2


it wont even let me make menuconfig in the gentoo livecd, it says unknown command or something similar.

however, it couldnt even get that far. And when i bootup the Gentoo livecd, it says there is no such thing as /mnt/gentoo where did it go?

Ok. Sorry, but I didn't remember this anymore. By the way, all Linux live-cds will show you the same, since this is nothing more than the list of the partitions on your disks.

This one is simple to tackle. When you get to the GRUB menu, press e to edit your configuration. Take note of your Linux entry. Then press c for the GRUB command and start typing your Gentoo entry. When you get to the kernel name, write the beginning of the file name and then press TAB for GRUB to complete the filename or show you the options. Select the proper option and then complete the line. When you finish writing the Gentoo entry, write in the next line boot and press ENTER. GRUB should now boot your system. Don't forget to update /boot/grub/grub.conf.

You're missing a few important details and mounting partitions at an incorrect dir. You should do:
Code:
# mkdir /mnt/gentoo
# mount /dev/hda8 /mnt/gentoo
# mount /dev/hda6 /mnt/gentoo/boot
# mount -t proc proc /mnt/gentoo/proc
# cd /boot
# ls
# chroot /mnt/gentoo /bin/bash
# env-update
# source /etc/profile
# cd /usr/src/linux
# make menuconfig
# make && make modules_install
# cp /usr/src/linux/arch/i386/boot/bzImage /boot/kernel-version

Don't forget to update grub.conf to include support for the new kernel. You should keep an old kernel around just in case. You might want to post your grub.conf file so we take a look at it.
A final note, you don't need to chroot or to mount / if all you want is to edit a file under /boot, such as grub.conf. If you need to recompile the kernel, then you need to mount / and to chroot.

Well i tried going into grub, pressing e on gentoo, then c, but when i got to the command line i didnt know what to type, but i tried:

Code:
kernel /kernel2.6.12-gentoo-rc6
Error: 15


so that didnt work, i did the
Code:
make && make modules_install
and that went all good
but when i try to
cp /usr/src/linux/arch/i386/boot/bzImage to /boot/(kernel version)
it says there is no bzImage in /boot

Im sorry but i dont know where my other kernel will be placed, or where my new one will be placed so i dont know if i can supply you the details, I also dont want multiple copies of kernels lying around since Im about to recompile it again this just may take up space. I dont understand why i would need to recompile my kernel after i finished installing my system.

can you please tell me how to find my bzImage and how to transfer it, this may be the problem after all. Thanks for your support so far its been absolutely outstanding.

Are you sure that you're doing the following?
Code:
# cp /usr/src/linux/arch/i386/boot/bzImage /boot/kernel-version

Don't forget replacing version with your kernel version, such as kernel-2.6.14-r2. You're not trying to install in an AMD64 or an Intel EM64T, are you? If so, replace the previous line with
Code:
# cp /usr/src/linux/arch/x86_64/boot/bzImage /boot/kernel-version

To boot from the GRUB command line, all you have to type into the command is the following. Don't forget to use the TAB key to determine the kernel name.
Code:
grub> root (hd0,5)
grub> kernel /kernel-2.6.12-gentoo-rc6 root=/dev/ram0 init=/linuxxrc ramdisk=8192 real_root=/dev/hda8 udev
grub> boot

Are you sure that your kernel isn't kernel-2.6.12-gentoo-r6?

Thanks the grub thing worked, it loaded up and booted, but a few things didnt load with the little [!!] but it got to tux_login and it wouldnt accept my password, i havent got to create a user yet anyway.

and it wouldnt let me copy bzImage, infact, when i TAB TAB the cp /usr/src/linux/arch/i386/boot/ directory it didnt even say there was a bzImage in there at all.
Also yes im using an amd64, and i tried both i386 and x86_64 folders but none of them contained bzImage.

Well, that means you're almost there. You just have to boot with the live-cd again, mount the partitions, chroot and then runn passwd. That will set your root password. When you try again to boot and use the GRUB command shell, you should be able to boot your system and login. In fact, if you remember the correct kernel name, you can take the chance and update your grub.conf file while you're in the chroot.
Just to show you, this is the output from my AMD64 system:

Ok....

i loaded up grub, pressed e, then c:
Code:
grub>kernel /kernel-2.6.12-gentoo-rc6

[linux-bzImage, setup=0xlc00, size=0x20f74c]
grub> boot


then it come up with a few errors relating to
Code:
Cannot start dev/SWAP
Error: Problem starting needed services "netmount" was not started


then it come up with
Code:
This is tux.unkown_domain (kernel-2.6.12-gentoo-rc6) 12:05:57

tux login: tux
Password: tux
login incorrect


i also tried
Code:
tux login: root
Password: (root password)


im pretty sure i never set a tux login or password, i also tried passwd and set a root password which did not work when i tried it.

You have to run passwd when you boot with the live-cd. It seems you've also forgotten to update /etc/fstab So boot with the live-cd, mount the partitions, chroot, update grub.conf and fstab and run passwd to set your root password. Then reboot and see if you can start your new system.

When you boot your system do the following
Code:
# ls -l /boot

Look at the kernel name. Then edit grub.conf and replace the kernel name with your kernel name.
Code:
# nano -w /boot/grub/grub.conf

Your Gentoo entry must look like the folllowing
Code:
root (hd0,5)
kernel /kernel-??? root=/dev/ram0 init=/linuxxrc ramdisk=8192 real_root=/dev/hda8 udev

Replace the kernel-??? with the correct kernel name. After that, you should be able to boot your system from the GRUB menu. If you can't make GRUB work, post the output of ls -l /boot.

Try using the following in grub.conf
Code:
root (hd0,5)
kernel /kernel-2.6.12-gentoo-rc6 root=/dev/hda8 udev

Hi, I have the following partition table

Code:

Disk /dev/hda: 60.0GB, 60011642880 bytes
255 heads, 63 sectors7track, 7296 cylinders
Device     boot           Start            End                Blocks                      Id           System
/dev/hda1 *           1                 2550              20482843+                 7              HPFS/NTFS
/dev/hda2              2551            2556              128520                     83            Linux
/dev/hda3              2567            2707              1132582+                 82            Linux swap / Solaris
/dev/hda4              2708            7296              36861142+               83           Linux


In the /dev/hda1 partition windows xp is installed.

This is my grub.conf file

Code:

default 0
timeout 30
splashimage = (hd0,0)/grub/splash.xpm.gz
title=Gentoo Linux 2.6.14-r2
root (hd0,1)
kernel /kernel-2.6.14-r2 root=/dev/hda4 video=vesafb:mtrr,ywrap,1024x768-16@60

title = windows XP
rootnoverify (hd0,0)
makeactive
chainloader +1


With this configuration while gentoo starts properly when I try to launch windows XP I get this message:

Code:
Error 1: Filename must be either an absolut pathname or blocklist


Where is the error?

I apologize for my English.

Thanks in advance.

Hi.

According to your description, your grub.conf file must have an error. If /dev/hda is an NTFS partition your /boot must be /hdev/hda2 Therefore, the splashimage must be on (hd0,1).
Code:
default 0
timeout 30
splashimage = (hd0,1)/grub/splash.xpm.gz
title=Gentoo Linux 2.6.14-r2
root (hd0,1)
kernel /kernel-2.6.14-r2 root=/dev/hda4 video=vesafb:mtrr,ywrap,1024x768-16@60

title = windows XP
rootnoverify (hd0,0)
makeactive
chainloader +1

I can't see how you get that error. You didn't overwrite the NTFS partition, right?

You're right I changed the splashimage to hd0,1 and the graphics is far more better now.

I hope I didn't overwrite the windows partition, how can I verify if Windows XP still works?

When I launched fdisk for the first time it told me that there could be problems caused by a certain number of cylinders or something like that. Could this be the cause of the problem?

Hi everybody,

I'm trying to install Gentoo for the first time (my first time compiling my kernel as well), and I've made it all the way to the bootloader without any apparent problems. I installed GRUB to my root partition (I have no separate /boot partition), set my root partition as active in fdisk and set up grub.conf (this is the way I've always done things with other distros). Upon reboot, GRUB pops up as expected. WindowsXP boots fine from the GRUB menu. When I try Gentoo, I get this error:
Code:
Error 13: Invalid or unsupported executable format

My grub.conf is as follows:
Code:
# default os
default 0
# wait before booting default; null for no timeout
timeout null
# splash image
splashimage=(hd0,1)/boot/grub/splash.xpm.gz

title=Gentoo Linux 2.6.12-r10
# kernel location
root (hd0,1)
kernel /boot/kernel-2.6.12-gentoo-r10 root=/dev/hda2

# for windows
title=Windows XP
rootnoverify (hd0,0)
chainloader +1

Any help with this would be much appreciated.

nihil39,

you can check if everything is ok with your NTFS partition by mounting it under Gentoo. If you can see the contents of your partition, you didn't overwrite it. After booting and logging in as root do the following
Code:
# mkdir /mnt/windows
# mount -t ntfs /dev/hda1 /mnt/windows
# ls -l /mnt/windows
