yet another grub 22 error thread

[jijin]

Ok here is the thing, In recently did a complete wipe of my HDD and installed ubuntu formatting the whole drive.

However, when I reboot I get error 22. I had at one time Vista installed on this but I installed ubuntu over the whole drive, so it shouldn't even have installed grub.

please help

I have tried doing


sudo grub
find /boot/grub/stage1

But I get in return:


Error 15: File not found

thanks

Check to see whats in your /boot/grub/ directory. I have a feeling its empty, if it can´t find stage1.

If this is the case, let me know. You will have to mount the hard drive, change root, install grub, and update grub to get a menu.lst generated.

ubuntu@ubuntu:/boot$ cd grub
bash: cd: grub: No such file or directory

:/

EDIT:

I realize now that that is only the live CD install. In the HDD under places there is no folder "/boot/grub" either

You are in the LiveCD file system not your installed ubuntu file system.

Please provide output of


sudo fdisk -l

for better help.

From the LiveCD mount your hard drive and change root


sudo mkdir /mnt/root
mount -t ext3 /dev/sda1 /mnt/root
sudo mount -t proc none /mnt/root/proc
sudo mount -o bind /dev /mnt/root/dev
sudo chroot /mnt/root bin/bash

The command prompt should now look like this

root@ubuntu:/#

Now reinstall and update grub (make sure you regenerate menu.lst)

sudo grub-install /dev/sda1
sudo update-grub
ls /boot/grub

This will provide you with a grub folder with all the required files including regenerating menu.lst file.

Ok I'm not sure if the commands you give below "Now reinstall and update grub (make sure you regenerate menu.lst)" do that but not aptitude is no longer working either.

Note: It might say unable to resolve ubuntu, but my internet is working. I am posting this from the live CD.


root@ubuntu:/# sudo grub-install /dev/sda1
sudo: unable to resolve host ubuntu
sudo: grub-install: command not found
root@ubuntu:/# sudo apt-get remove grub
sudo: unable to resolve host ubuntu

I can and don't mind reinstalling from scratch, but I want to make sure I don't have the same issue all over again.

EDIT: I'm going to reinstall it from scratch

Pardon me if you already checked this, but I fixed a Grub error 22 by correcting my drive cabling. My Sata drive motherboard sockets were populated (clue was from from start up bios report):

Sata1: empty
Sata2: empty
Sata3: master 1
Sata4: master 2

Grub was happy after this:

Sata1: master 1
Sata2: master 2
Sata3: empty
Sata4: empty

When I first built the system I did not think it mattered to plug the cables in strict order (or my old eyes misread the small print). Apparently, the later versions of Ubuntu are picky at load about cabling. This can happen from plugging the IDE in reversed (drive header into motherboard socket) also. The install CDROM worked fine, as did XP, but not the Grub loader from the actual installation. Even with the first two Motherboard Sata sockets empty, the CDROM Kubuntu numbered them sda and sdb.

Hope this helps, cheers

This might be a problem with the CD you are using. Here is some general tips regarding the CD

Download the standard Ubuntu 8.04.1 32 bits iso image, torrent is recommended
http://releases.ubuntu.com/releases/8.04.1/ubuntu-8.04.1-desktop-i386.iso
http://releases.ubuntu.com/releases/8.04.1/ubuntu-8.04.1-desktop-i386.iso.torrent

Check the md5sum of your downloaded Ubuntu .iso image file https://help.ubuntu.com/community/HowToMD5SUM
and compare with http://releases.ubuntu.com/8.04.1/MD5SUMS

Burn it on a CD rom with low speed 4X and then check the md5sum of the burnt CD

Try to perform the "Memory test" and the "Check CD for defects" to be sure the CD is read without errors by the destination PC CD rom driver

Then reinstall your Ubuntu

Hope this helps
