Does this look correct to you??

One more thought. This computer is mainly my Windows 7 machine which I had dual booted and it is giving me the problems right now. I have two other computers that only have Ubuntu on them and those are the ones that I use most. Do you think there would be a way for me to just get windows booting on this machine on this drive. Later I could add another drive and put ubuntu on that if I want, but since I have the other two computers setup with Ubuntu I really do not have to have it on this machine right now.

Is where a difference in the two hard drive? Is one of them Sata and the other IDE?

A couple of more things to try before reinstalling:

See what happens if you swap the physical position of the hard drives.
Check on the setting in your bios (see my last post)
See whether there is a update available for your Bios.

Let me know what you think about the reinstall

That should work. It should even be enough to create a boot partition on the other drive (let me know if you would like help with creating boot partition)

That's weird. apt-get refused to remove "grub-pc". So you still have Grub 2 installed. You did mess up at least once:

sudo cp /etc/resolv.conf /mnt/etc
ubuntu@ubuntu:~$ sudo chroot /mnt
root@ubuntu:/# dpkg-divert --local --rename --add /sbin/initctl

sudo mount /dev/sda2 /mnt
sudo: unable to resolve host ubuntu
root@ubuntu:/# for i in dev proc sys dev/pts; do sudo mount --bind /$i /mnt/$i;done

The mount commands have to come before the "chroot" command.

But that does not explain why "grub-pc" did not get removed.
You might try again and make sure to follow the instruction exactly.

Do you think there would be a way for me to just get windows booting on this machine on this drive.

Maybe. If that works, it might even be possible to add Ubuntu to the Windows boot loader.

Try this (still with only the Ubuntu drive attached)

sudo apt-get install lilo

(ignore the warnings, just press enter)

sudo lilo -M  /dev/sda mbr

Reboot. You should boot right into Window 7.

do you have the windows 7 install dvd
if so then its possible to get windows 7 running
this thread should give you some additional info

Maybe "apt-get" will be happier if you upgrade those packages before trying to remove "grub-pc":

sudo mount /dev/sda2 /mnt
for i in dev proc sys dev/pts; do sudo mount --bind  /$i /mnt/$i;done
sudo cp /etc/resolv.conf /mnt/etc
sudo chroot /mnt
dpkg-divert --local --rename --add /sbin/initctl
ln -s /bin/true /sbin/initctl
apt-get update
apt-get upgrade
apt-get purge grub-pc grub-common
apt-get install grub grub-common
grub-install --recheck /dev/sda
update-grub
rm /sbin/initctl
dpkg-divert --local --rename --remove /sbin/initctl
exit
for i in dev/pts dev proc sys /; do sudo umount /mnt/$i;done

Thanks meierfra,

I tried everything and the disk will still not be recognized during start up.

I had the drive backed up with Acronis and did a restore and it took all day which seemed odd. It did restore with all the partitions and the original boot loaders, but it still was not being recognized at start up. So my guess is that the drive has gone bad. I just put in a new drive and am doing a restore now (taking less than two hours).

I will post later on how this goes. Hopefully all I will have to do is get the new configuration to boot correctly.

I surely do appreciate all of your effort in helping me with this and wish that I could reciprocate, but you are far better at this than I. I will just try to help the next person in line with the problems that I can solve.

[lindsay7]

The blue bird of happiness is flying again. The restore worked and I have windows and ubuntu back again. The last thing you want to think about is a drive that unexpectedly bites the dust but it happens.

Thanks again for the hand holding and support.

I had similar problem: after reinstallation of grub 2 i had only "grub>_". when tried grub-mkconfig had "cannot find a device for /.". But instructions at 7th post ( http://ubuntuforums.org/showpost.php...09&postcount=7 ) helped me. Thx lindsay7 for starting this topic and meierfra. for the solution.
