Disk drive for / not ready on boot after upgrade from 10.04 to 12.04

Hi ,
try to use this automate tool :
https://help.ubuntu.com/community/Boot-Repair#A2nd_option_:_install_Boot-Repair_in_Ubuntu

and try to repair the boot.

You can run the tool from a Ubuntu Live CD-USB , just boot from there and follow the instructions.

Thanks

Hi,

Thanks for your answer. I followed the instructions and Boot repair asked me to run the following command in a terminal:

sudo chroot "/mnt/boot-sav/sda2" apt-get -f install

I ended up with the following error:

E: Could not perform immediate configuration on 'python2.7-minimal'.Please see man 5 apt.conf under APT::Immediate-Configure for details. (2)

After some googling, I found this: https://bugs.launchpad.net/ubuntu/+source/python-defaults/+bug/990740

The solution many people are saying worked seems to be when using from within Lucid, while I'm on a live CD. I tried to run:

sudo chroot "/mnt/boot-sav/sda2" apt-get install -o APT::Immediate-Configure=false -f apt python-minimal

But got lot of dependencies error as output, similar to #34 in the above thread. I will be awaiting further instructions, thank you agian!

Did you install using Wubi, or did you resize your NTFS and install to the new freed space??

As mentioned in my original post, I didn't use Wubi or resize my NTFS. I installed 8.04 first and left free space on the HDD for an eventual Windows partition.

Try:

sudo apt-get install --reinstall python-minimal -o APT::Immediate-Configure=false

That does reinstall python, on the live CD however. I tried to prepend the command (minus sudo) with:

 sudo chroot "/mnt/boot-sav/sda2"

to no avail.

What LiveCD did you used ? What version of Ubuntu ? You have to use 12.04 Live CD , not 8.04 and run again the boot-repair.

If the problem is in python breakage then I assume that re-install needed to correct all these packages.

You can re-install without to remove you personal files. Pay attention to installer window , it will give you the option for "something else" click this option and then follow these pictures

I used the LiveCD for 12.04 x64 downloaded and burned yesterday. The host system is a 8.04 x64 previously upgraded to 10.04 x64 and that I know tried to upgrade to 12.04 x64 (which made everything break). I have investigated my issue further:

Since running

apt-get -f install

after remounting / in read-write doesn't do it for me (I got dependency errors, see http://paste.ubuntu.com/1338058/), and the solution mentioned above in https://bugs.launchpad.net/ubuntu/+source/python-defaults/+bug/990740 where most people say the solution that worked is running:

apt-get install -o APT::Immediate-Configure=false -f apt python-minimal

doesn't do it either (see http://paste.ubuntu.com/1338070/), I read that running:

dpkg --configure -a

could help. At first it wouldn't run because it had trouble parsing /var/lib/dpkg/status since there was an extra blank line in a package description (see https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/916799) but I removed it using vim (and then reran the command). It still gives me output that looks like an error, though. Here it is: http://paste.ubuntu.com/1338074/. I also tried re-running the above apt-get commands after that, to no avail.

You're saying the only solution now is to do a fresh install? Perhaps with all the information that I just provided there is a better way, before resorting to reinstall. Also I imagine if I were to proceed with reinstall I would need to select ext3, not ext4, as it's what my partitions (created in 2008) use.
