I moved this to a new thread since it's not related to the xorg problem where it was posted. That was marked as solved, this is not.

| I have the Aptosid LiveCD up, and have setup the chroot environment. Don't have network access on it. I did copy grub-common, grub2 and grub-pc ( all v. 1.98+20100804-14_amd64 ) debs onto a flash drive. These versions should work? But I can't figure out how to copy the files from the flash drive onto the hd. If I can do this, I should be able to install with dpkg and be back up again, right? |

| I did boot from the livecd, setup a chroot env, and downgraded grub-pd, grub-common, and grub2 to those versions using dpkg. Then I did an update-grub, but when I rebooted it still tossed me to grub rescue. I copied those files from a flash drive because I don't have, right now, and easily accessible network connection for the box. What am I missing? |

I had not needed my Super Grub CD for a couple of years, but I needed it today.
Code:
root@aptosidbox:/home/don# apt-cache policy grub-pc
grub-pc:
Installed: 1.99~rc1-2
Candidate: 1.99~rc1-2
Version table:
*** 1.99~rc1-2 0
500 http://cdn.debian.net/debian/ sid/main amd64 Packages
500 http://ftp.us.debian.org/debian/ unstable/main amd64 Packages
100 /var/lib/dpkg/status
but, except for that little excitement, the new kernel booted fast and my desktop never looked better.
Code:
root@aptosidbox:/home/don# infobash -v3

I could have used that. I made a mess of things and decided to reinstall the system. But there is a hidden problem that should be made known.
I have an Edimax EW-7128G wireless card that is only supported in non-free. During the fresh install I'm presented with a screen telling me that I have to get non-free to support the hardware, and asks if I want to do this. Of course, I do. The trap is that doing this also brings in the broken grub-pc 1.99+ package. So after everything is installed and I reboot, I of course get the broken grub and grub-rescue prompt.
Since the broken grub-pc package is a known issue, there should be some mention of it during the install. Otherwise, and I'm sure it's happened, others will fall into this.

But... this "known issue" occured after the latest aptosid release, so installer can't mention it...
And whatever package you need to install after install, you can still hold the grub-common
package with
# echo grub-common hold | dpkg --set-selections
or see http://manual.aptosid.com/en/sys-admin- ... -downgrade |

| So, with the unbootable system, would I boot to the live cd, then set up a chroot environment, and then follow those downgrading instructions using the testing repositories to install the previous, working version of grub-common? Not to sound dense... |

Don't know. All I get is a grub_rescue prompt, just like http://bugs.debian.org/612806 . Is the process I described the correct way to downgrade grub-common after another reinstall? Appreciate any help.
Squeeze is still at 2.6.32 and I doesn't load the k10temp module I would like to use. |

For broken system, I think downgrading and update-grub would recover the grub.
I didn't have problem with upgraded version of grub on 2 system (i386 and amd64).
I don't know what is the condition to be broken... |

| I'll try again in a bit. I have a second hard drive on this system, not sure if this has any bearing on the problem. |

OK this is what I did. I don't remember which forum it came from or I'd give credit for it. I'm NOT recommending this however, it did work for me.
Code:
mount /dev/sdXx /mnt
mount -o bind /dev /mnt/dev
mount -o bind /sys /mnt/sys
mount -o bind /proc /mnt/proc
chroot /mnt
Once at the prompt I reinstall grub:
Code:
grub-install /dev/sda
and then updated grub
Code:
update-grub
The grub-install might have had to be /dev/sdaX I can't remember this happened to me over a week ago the first time.
Again, I'm not "recommending this". However...It worked on all four of my boxes.
Regards,
Deach |

| After I had the problem as reported above, I downgrade the grub-pc version, then waited until yesterday to d-u. It upgraded grub-pc (and many other things), and now it boots fine. Also one of my netbooks which had not been updated for a couple of weeks just got a d-u, and there's no problem there. |
