This is my second time installing, and I got the same problem.
GRUB would not load properly. So I went into command line by pressing 'C'.
| Code: |
completitions of a device/filename. ESC at any time exists. ]
grub> root (hd0,0)
Filesystem type is ext2fs, partition tpe 0x83
grub> kernel /
Possible files are : lost+found .keep boot kernel-2.4.28-gentoo-r5 System.map=2.4.28-gentoo-r5 config-2.4.28=gentoo=r5 grub

This is the part that was so hard to explain last time, because grub uses the word 'root' to mean three different things!
I never did get 'grub-install' to work as i expected it to, or the 'TAB' key in a manual install. So i use the 'Alternative: Setting up GRUB using manual instructions' section of the handbook, & type each command in full. So, from your normal bash-prompt, enter the command 'grub' to get a grub-prompt (grub>) | Code: | root / # grub
grub> |
Next, to tell 'grub' where to find it's own files at boot-time, enter the command 'root (hd0,0)'
...That tells 'grub' that the files it uses to load the kernel are on the 1st partition of the 1st hard-drive, 'hda1', which is where your /boot directory is.
Next, embed 'grub' into the Master Boot Record (MBR) of the 1st hard-drive
Finally, exit back to the bash-prompt with the command 'quit' | Code: | grub> quit
root / # |
Note: The bash-prompts i've listed are examples only - yours may well be different. Also, the values in brackets, (hd0) & (hd0,0) use the number zero, not a capital-O.
Let us know if you need anything about the 'grub.conf' file explained. Don't feel embarrassed if you do - like i said, there are three uses of the word 'root' to get your head round.

If you get to this, it means GRUB is installed.
Type: | Code: | kernel kernel-2.4.28-gentoo-r5
boot |
You should see messages from the kernel as it loads you kernel and probes for devices.
If you see a message about being unable to mount your root partition, it means you have not correct set up your /etc/fstab file.
You will have to start off a LiveCD, mount your partition and make sure your entry for / in /etc/fstab is correct.
If the system boots ok, Edit /boot/grub/grub.conf to match what you entered on the GRUB command line. Then do the sets that were outlined above by taipan67 to reinstall GRUB into the MBR of the disk. |

To taipan67:
How do I get back to root from grub? Or do I go back to root by putting in the CD?
To Headrush:
When I entered
| Code: |
grub> kernel kernel-2.4-28-gentoo-r5 |
I was returned with
| Code: |
Error 1: Filename must be either an absolute pathname or blocklist |

But how did you get to the grub-prompt if you didn't have the CD in, already?

Hit tab and you should see all the commands Grub understands.
Could be exit, but I thought it was quit also.
If you need to, usr CTRL-C, it shouldn't hurt, the program already wrote to the disk. |

What version of Grub do you have?
I have version 0.94 and quit is in there.
Additionally. CTRL-C should end any terminal based program.
What LiveCD are you using? |

I've had an idea...
I think you can't 'quit' from the grub-prompt because there's no root-prompt to quit back to! I'm guessing that you've finished the install process, rebooted with the LiveCD removed, & got the grub-prompt instead of a login-prompt? This would probably happen for one or more of three reasons:-
1. Grub wasn't installed properly.
2. Grub was installed properly, but can't load the kernel because 'grub.conf' is wrong.
3. The above steps are okay, but /etc/fstab is wrong.
I think grub has been installed properly, because it's booting to the prompt. So it's probably either 2 or 3. To fix this, you need to reboot with the LiveCD, mount your partitions & chroot into your new system, then follow the handbook & the earlier posts to re-configure those files.
Post any specific questions you have about that, & if Headrush & anybody else have any observations to add, or corrections, could they please post them, also...

You have to mount the partition first. | Code: | mount /dev/hda3 /mnt/gentoo
mount /dev/hda1 /mnt/gentoo/boot |
Then you can do the chroot. |

The 2nd one's no problem - you can't mount hda1 because it's mount-point (/mnt/gentoo/boot) is on hda3, which isn't mounted yet.
The 1st one...
Try the 'mount' command without any arguments - it will list all filesystems currently mounted. | Code: | | livecd root # mount |
...If /dev/hda3 doesn't show up as already mounted (which it shouldn't), running 'fsck' ought to tell you the true filesystem. | Code: | | livecd root # fsck /dev/hda3 |
...Based on earlier posts, you should see something about 'reiserfs', which i believe you were using for your / (root) partition. Assuming that is confirmed, try to mount it by specifying the filesystem-type... | Code: | | livecd root # mount -t reiserfs /dev/hda3 /mnt/gentoo |
If that works, you can then mount /dev/hda1, & carry on with your editing...

Thank you for responding early in the morning. I thought I was the only one who goes directly to the computer the moment I wake up.
| Code: |
livecd root # mount
/dev/ROOT on / type xfs (rw,noatime)
/newroot/dev/cdroms/cdrom0 on /mnt/cdrom type iso9660 (ro)
/dev/loop/0 on /mnt/livecd type squashfs (ro)
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev type ramfs (rw)
none on /dev/pts type devpts (rw)
none on /dev/shm type tmpfs (rw)
tmpfs on /usr/lib/hotplug/firmware type tmpfs (rw)
none on /proc/bus/usb type usbfs (rw)
|
| Code: |
livecd root # fsck /dev/hda3
fsck 1.35 (28-Feb-2004)
e2fsck 1.35 (28-Feb-2004)
Couldn't find ext2 superblock, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/hda3
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with alternate superblock:
e2fsck -b 8193 <decide>
|
| Code: |
livecd root # mount -t reiser /dev/hda3 /mnt/gentoo
ReiserFS: hda3: warning: sh-2021: reiserfs_fill_super: can not find reiserfs on hda3
mount: wrong fs type, bad option, bad superblock on /dev/hda3
or too many mounted file systems
|
What does all this mean? Even though I can read the English parts, I still do not understand what my computer is trying to tell me.  |

My computer doesn't get switched off - when i get up (7am, in this case) i just nudge the mouse to see how overnight downloads & emerges are doing... 
The 1st code-snippet looks good - no hard-drive partitions are currently mounted.
The 2nd one... When you invoke fsck (filesystem-check) without specifying a filesystem-type, it tries to identify the filesystem-type before running the appropriate program (for example, e2fsck for ext2 & ext3 filesystems).
The snippet you've posted suggests that you've changed your mind, & made your / (root) partition either ext2 or ext3, instead of reiserfs. Can you confirm which filesystem-type you used before i or anyone else offers tips on fixing it?
For myself, i'll need to do some research before advising what to do next. If nobody else suggests anything within a few hours, it might be worth starting a fresh topic - again, in the 'Installing Gentoo' forum - on this particular problem, in order to attract the attention of people who aren't watching this thread. Bear in mind that users in America will probably be asleep for another 4 or 5 hours...
If you do start a fresh thread, a good title might be '"fsck: bad superblock" help req.d'. Try to include a link to your previous post here. The url is https://forums.gentoo.org/viewtopic.php?p=2054351#2054351
Please confirm the filesystem-type you believe you used, & i'll try to find out how to fix superblocks (if it's necessary).

I have not changed my mind on the filesystems. They are still:
| Code: |
Device Boot Start End Blocks Id System
/dev/hda1 * 1 63 31720+ 83 Linux
/dev/hda2 64 576 258552 82 Linux swap
/dev/hda3 557 25209 12415032 83 Linux
|
hda1=ext2
hda2=swap
hda3=reiserfs
Anyway I can check on my filesystems? |

I haven't got a manual-page for the reiserfs-checking utility, because i don't use reiserfs. The manual-page for 'fsck' refers to both 'fsck.reiserfs' and 'reiserfsck'. I have no way of knowing if they are the same thing, or if it's a typing error in the manual-page.
Whichever one is correct, you could try | Code: | | livecd root # fsck.reiserfs /dev/hda3 |
...or | Code: | | livecd root # reiserfsck /dev/hda3 |
...& see if anything is found to be wrong &/or fixable...
Any suggestions from users of reiserfs would be appreciated...

They're the same thing, so either command will do fine.

Yo, Cyberian!
Does 6 hours of silence mean that you've fixed the problem, or that it's sleep-time in your part of the Global Village?
If the problem's not solved, i've developed a couple of (slightly bizarre) ideas from googling for that 'warning: sh-2021' thing. Drop us a quick post if you need me to explain further...

Hi,
Sorry about not replying earlier; I was asleep. I came straight to my computer the moment I woke up.
| Code: |
livecd root # fsck.reiserfs /dev/hda3
reiserfsck 3.6.18 (2003 www.namesys.com)
*****************************************************
** blah, blah, blah, blah, blah, blah, blah, blah **
** support is available for $25 at www.namesys.com **
*****************************************************
Will read-only check consistency of the filesystem on /dev/hda3
Will put log info to 'stdout'
Do you want to run this program?[N/Yes] (note need to type Yes if you do):yes
livecd root # _
|
Okay, so this means I do have reiserfs as my hda3, right? So what is my computer's program with detecting it? |

The only stuff i could find through google was similar problems, but no solutions. They did, however, suggest the problem might be with detecting the actual hard-drive, not just the file-systems on it.
You can test this by trying to mount your 1st partition, hda1, by itself. It'll be a bit complicated, because it won't be called '/mnt/gentoo/boot', it'll be called '/mnt/gentoo'. Because this partition is ext2, it'll tell us if the problem is drive-related or reiserfs-related. So, try this command: | Code: | | livecd root # mount /dev/hda1 /mnt/gentoo |
...If it mounts without any problems, then the earlier problem is with reiserfs, not the drive.
If it doesn't mount, i'd like you to check your running kernel-modules, by running the command: | Code: | | livecd root # lsmod | more |
...The '| more' part means that if the output scrolls off the page, it will pause until you press the space-bar. The module that drives your motherboard's ide-controller is called 'sis5513' (i think). If you don't see it, you can insert it by running the command: | Code: | | livecd root # modprobe sis5513 |
...Then, try your 'mount' commands again. Let us know what you find out from that - as i said before, it's a slightly bizarre idea, but i'd like to rule it out.

OK. You were able to mount these partitions before with the LiveCD when installing Gentoo.
Assuming you are using the same LiveCD now, it should still see it. So it should not be a problem with loading a module with specific support for your chipset.
I am thinking somehow you were not in your chrooted environment properly when you did some of the installation. If this is the case, we may be headed for even more problems.
Might be better to just start over from the beginning to make sure everything is OK. I am away this weekend, but come Tuesday I would be willing to walk you through it step by step live. You can use an instant messenger from a live CD while you install.
Good luck and will be back monday.
It should not be this must trouble, so I think it was a previous step and to be safe a fresh start might be best in long run. |

Headrush is absolutely right about it being unlikely that the same LiveCD would give varying performance. I did say the ideas were slightly bizarre - i never said they made sense . They don't make much sense to me, & i know where i'm going with them...
Tell you what - humour me. Try the | Code: | | livecd root # mount /dev/hda1 /mnt/gentoo |
command, & see what happens... What have you got to lose?
