To rescue Grub after installation of Windows XP or on lost of MBR

Boot into the live Ubuntu cd. This can be the live installer cd or the older live session Ubuntu cds.

When you get to the desktop open a terminal and enter. (I am going to give you the commands and then I will explain them later)

Code:
sudo grub
This will get you a "grub>" prompt (i.e. the grub shell). At grub>. enter these commands

Code:
find /boot/grub/stage1
This will return a location. If you have more than one, select the installation that you want to provide the grub files.
Next, THIS IS IMPORTANT, whatever was returned for the find command use it in the next line (you are still at grub>. when you enter the next 3 commands)

Code:
root (hd?,?)
Again use the value from the find command i.e. if find returned (hd0,1) then you would enter root (hd0,1)

Next enter the command to install grub to the mbr

Code:
setup (hd0)
Finally exit the grub shell
Code:
quit
That is it. Grub will be installed to the mbr.
When you reboot, you will have the grub menu at startup.

Now the explanation.
Sudo grub gets you the grub shell.
Find /boot/grub/stage1 has grub locate the file stage1. What this does is tell us where grub's files are. Only a small part of grub is located on the mbr, the rest of grub is in your boot folder. Grub needs those files to run the setup. So you find the files and then you tell grub where to locate the files it will need for setup.
So root (hd?,?) tells grub it's files are on that partition.
Finally setup (hd0) tells grub to setup on hd0. When you give grub the parameter hd0 with no following value for a partition, grub will use the mbr. hd0 is the grub label for the first drive's mbr.
Quit will exit you from the grub shell.

DVD Data Recovery on Linux

After reaching B'glore... it is hectic...

But found a way to have successful data recovery on linux..

Tools : ddrescue, dares-qt

fireup ddrescue

ddrescue -b 2048 -v -r 0 -n /dev/dvd /path/to/image.img logfile

This will save the image of dvd as image.img
---------------------------------------------------------------------
Note:
Disabled splitting error areas and retries for maximum speed.

---------------------------------------------------------------------
Then start dares-qt

dares-qt -i /path/to/image.img -s /path/to/save/

It will scan the image.img file for files and will display the files to be saved...

Save one by one... !!!!
That is all....

എവിടെയോ എന്തൊക്കെയോ..

ഈ ബോംബെ ... അല്ല (മുംബൈ) ജീവിതം എന്നെ എന്തൊക്കെയോ ആക്കി മാറ്റുന്നു.. തിരക്ക് പിടിച്ച ഓഫീസ്... അതിനെക്കാളേറെ ടെന്ഷന്... ഓരോ വിമാനം ഇറങ്ങുംപോഴും ഓരോന്ന് പൊങ്ങുംപോഴും വല്ലാത്ത ഒരു ആശ്വാസം... ഓരോ ദിവസവും ഡ്യൂട്ടി കഴിയുമ്പോള് ഇന്നു rating പോവാത്തതിന്റെ ആശ്വാസം ...

അതിനിടയില് ഇവിടെ കൂടി എന്തെങ്കിലും കുത്തിക്കുറിക്കുക എന്നത് അപ്രായോഗികം..!!

പുതിയ ബാംഗ്ലുര് എയര്പോര്ട്ടിലെക്ക് ഇതിനിടയ്ക്ക് ഒരു സ്ഥലം മാറ്റവും..!!!
