Grub rescue prompt, repair grub

I recently repartitioned my hdd and I have damaged grub on my system. On boot I get the grub rescue prompt and I have to go through the following steps in order to boot normally:

> ls   //to view partitions

> set root=(hd0,msdos6)
> set prefix=(hd0,msdos6)/boot/grub
> insmod normal
> normal 

Then i just install boot-repair:

> sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update

> sudo apt-get install -y boot-repair && (boot-repair &)

Installing Catalyst 13.4 on Ubuntu 13.04

Manually installing Catalyst 13.4

Before you go about installing the fglrx driver from AMD Catalyst 11.10 do read the release notes.

In this how-to an AMD64 Ubuntu 11.10/12.04 installation using a AMD Radeon HD 6300M will be chosen for illustrative purposes.

Note: Remember to uninstall the AMD proprietary fglrx graphics if it is already installed and reboot your system.

1. Download the drivers found at the AMD website. To avoid complications later on, save it inside an empty folder.
2. Enable the Source Code repository in Synaptic Package Manger, then open a terminal and type:

   sudo apt-get update

   On a standard desktop install of Ubuntu 10.10 you may also need to install the QT4 libraries, to do this type:

   sudo apt-get install libqtgui4

   On a standard desktop install of Ubuntu 12.04 you may also need to install dh-make libraries, to do this type:

   sudo apt-get install dh-make dh-modaliases execstack libc6-i386 lib32gcc1

   Note: This is not necessary if you are running Kubuntu or have already installed the libraries.
3. Still using the terminal, navigate to the folder where you downloaded the drivers.
   1. Ubuntu 13.04 Raring:

      sh amd-driver-installer-catalyst-13-4-x86.x86_64.run --buildpkg Ubuntu/raring

   2. Ubuntu 12.04.2 LTS Precise:

      sh amd-driver-installer-catalyst-13-4-x86.x86_64.run --buildpkg Ubuntu/precise

      
      If it is required, a package manager window will open and install some dependencies and after a while create the following three .deb packages:

      fglrx_12.104-0ubuntu1_amd64.deb  
      fglrx-amdcccle_12.104-0ubuntu1_amd64.deb  
      fglrx-dev_12.104-0ubuntu1_amd64.deb

      Note: It will also create a file called fglrx-installer_12.104-0ubuntu1_amd64.changes. If you wish you can read this file to know the changes that have been effected through AMD Catalyst 13.4 and related information.
4. To install the created .deb files, type:

   sudo dpkg -i fglrx*.deb

   Note: In case any of the packages are broken, open Synaptic Package Manager and go to Edit -> Fix Broken Packages. In case you are new to Ubuntu, broken here means that some dependent packages are not yet installed. Once you sort out the issue as indicated above through the Synaptic Package Manager, the problem of broken packages should be resolved.
5. Continuing with the installation, type:

   sudo aticonfig --initial

   After this command, reboot your system. If all is right, the fglrx driver that corresponds to AMD Catalyst 12.3 will be installed and working on your system. To confirm the drivers are working open a terminal and type:

   fglrxinfo

   You should get an output similar to the following:

   fglrxinfo 
   display: :0  screen: 0
   OpenGL vendor string: Advanced Micro Devices, Inc.
   OpenGL renderer string: AMD Radeon HD 6300M Series
   OpenGL version string: 4.2.11733 Compatibility Profile Context

   Note: If you see any mention of MESA in the output, the fglrx drivers have not been installed correctly. See the troubleshooting section for more details You can make configuration changes through the AMD Catalyst Control Center, it can either be found in your Application menu or you can launch it through a terminal like this:

   gksudo amdcccle 

   To read more about the AMD Catalyst Control Center click here. Keep in mind that all configuration options for the AMD Catalyst Control Center mentioned there may not be available for your Ubuntu system.

Install the JDK 7 on Ubuntu 13.04

• Download he 32bit or 64bit Linux "compressed binary file" - it has a ".tar.gz" file extension i.e. "[java-version]-i586.tar.gz" for 32bit and "[java-version]-x64.tar.gz" for 64bit
• Uncompress it
  tar -xvf jdk-7u2-linux-i586.tar.gz (32bit)
  tar -xvf jdk-7u2-linux-x64.tar.gz (64bit)

JDK 7 package is extracted into ./jdk.1.7.0_02 directory. N.B. check carefully this folder name since Oracle seem to change this occasionally with each update.

• Now move the JDK 7 directory to /usr/lib

sudo mkdir -p /usr/lib/jvm
sudo mv ./jdk.1.7.0_02 /usr/lib/jvm/jdk1.7.0

• Now run

sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.7.0/bin/java" 1
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.7.0/bin/javac" 1
sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.7.0/bin/javaws" 1

• Correct the file ownership and the permissions of the executables:

sudo chmod a+x /usr/bin/java 
sudo chmod a+x /usr/bin/javac 
sudo chmod a+x /usr/bin/javaws
sudo chown -R root:root /usr/lib/jvm/jdk1.7.0

N.B. remember - Java JDK has many more executables that you can similarly install as above. java, javac, javaws are probably the most frequently required.
This answer lists the other executables available.

• Run

sudo update-alternatives --config java

You will see output similar one below - choose the number of jdk1.7.0 - for example 3 in this list:

$sudo update-alternatives --config java
There are 3 choices for the alternative java (providing /usr/bin/java).

Selection Path Priority Status
————————————————————
* 0 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 auto mode
1 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 manual mode
2 /usr/lib/jvm/java-6-sun/jre/bin/java 63 manual mode
3 /usr/lib/jvm/jdk1.7.0/jre/bin/java 3 manual mode

Press enter to keep the current choice[*], or type selection number: 3
update-alternatives: using /usr/lib/jvm/jdk1.7.0/jre/bin/java to provide /usr/bin/java (java) in manual mode.

Check the version of you new JDK 7 installation:
java -version

java version “1.7.0”
Java(TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot(TM) Client VM (build 21.0-b17, mixed mode) 

Repeat the above for:

sudo update-alternatives --config javac
sudo update-alternatives --config javaws

Enable mozilla firefox plugin:

32 bit:
ln -s /usr/lib/jvm/jdk1.7.0/jre/lib/i386/libnpjp2.so ~/.mozilla/plugins/

64 bit:
ln -s /usr/lib/jvm/jdk1.7.0/jre/lib/amd64/libnpjp2.so ~/.mozilla/plugins/

N.B. you can link the plugin (libnpjp2.so) to /usr/lib/firefox/plugins/ for a system wide installation
Depending on your configuration, you might need to update the apparmor profile for firefox (or other browsers) in /etc/apparmor.d/abstractions/ubuntu-browsers.d/java

# Replace the two lines:
#  /usr/lib/jvm/java-*-sun-1.*/jre/bin/java{,_vm} cx -> browser_java,
#  /usr/lib/jvm/java-*-sun-1.*/jre/lib/*/libnp*.so cx -> browser_java,
# with those (or adapt to your new jdk folder name)
/usr/lib/jvm/jdk*/jre/bin/java{,_vm} cx -> browser_java,
/usr/lib/jvm/jdk*/jre/lib/*/libnp*.so cx -> browser_java,

Then restart apparmor:

sudo /etc/init.d/apparmor restart

Confirm that the JRE has been successful by using the official oracle website.
