We need a mail server for this purpose. For example : for sending mails to gmail, we have smtp server. There are various other softwares that are available on internet. If you have all the requirements then you can easily perform this task with the following code :

HTML code for this :

Problem : No init found

If you boot into your system and face this problem -
                No init found.Try passing init=bootary.
This problem can be simply solved using a live cd.Open terminal and type -                      sudo fdisk -l
This will list all the partitions.Look out for linux partition(it was /dev/sda9 in my case ) and then type -
                                  sudo fsck /dev/sda9
press 'y' to fix all errors .When scan is finished,reboot the system and you can boot into system again :)

Recovery of GRUB after re-installing Windows

To get back your Grub, you need to boot your system using Ubuntu Live CD and after making your Cd work , follow these steps:

To check the version of Grub , in Terminal type- grub-install -v

GRUB2 should display a version number of 1.96 or later.If you don't

have Grub2 installed,you can install it from Synaptic.After that go to

Places and mount your Ubuntu partition.Then Go into boot/grub

directory and check for the existence of the file grub.cfg.

       Now you need to switch to the terminal-

Verify if you mounted the right partition by typing-

                    mount | tail -1 
It will show an output like this- 
/dev/sda9 on /media/0d104aff-ec8c-44c8-b811-92b993823444 type 
ext4 (rw,nosuid,nodev,uhelper=udisks)
To make sure this is indeed the Ubuntu boot partition,run-

ls /media/0d104aff-ec8c-44c8-b811-92b993823444

but replace '0d104aff-ec8c-44c8-b811-92b993823444' with your UUID.
Output of this command should be similar to this-
config-2.6.18-3-686        initrd.img-2.6.18-3-686.bak   System.map-2.6.18-3-686
grub                           lost+found                          vmlinuz-2.6.18-3-686
initrd.img-2.6.18-3-686    memtest86+.bin 
Now we just need to reinstall GRUB by specifying the correct 
directory and the correct drive name , type - 
 sudo grub-install --root-directory=/media/ 
0d104aff-ec8c-44c8-b811-92b993823444 /dev/sda

If all went well, you should see something like this-Installation finished. No error reported.
Now Reboot.Grub should be installed and both Ubuntu and Windows

should have been automatically detected and listed in the menu.
