Hello Friends, am back again with an amazing tips for you all. Today we'll learn how to recover linux grub after installing windows or other operating system. So lets get focused 😎
First of all just understand Linux in few sentence so that you can continue thereafter easily.

    What is Linux?

    Linux is an multiuser, multitasking operating system. An operating system is software that manages all of the hardware resources associated with your desktop or laptop. To put it simply – the operating system manages the communication between your software and your hardware. Without the operating system (often referred to as the “OS”), the software wouldn’t function.
    The main purpose of using linux as an operating system is o improve the system and features using command line interface.And i think you all knew about this :p

    What is Grub?

    GRUB (GRand Unified Bootloader) is a boot loader package developed to support multiple operating systems and allow the user to select among them during boot-up. It was originally designed and implemented by Erich Stefan Boleyn.

    Briefly, a boot loader is the first software program that runs when a computer starts. It is responsible for loading and transferring control to the operating system kernel software (such as the Hurd or Linux). The kernel, in turn, initializes the rest of the operating system

    What is Grub-Rescue?

    We have installed Linux (Ubuntu, Kali, Linux Mint, Monjaro, Fedora, Debian, Arch, etc.) many time in our computers/laptops. And many times we have seen this:-


    This happens due to removal of grub files that belongs to the grub loader installed in your computer. It also occurs when you delete/format the partitions where Linux is installed in your computer.

    How To Recover Grub?

    Well, this is the most complicated part as we all knew how to install linux but most of us don't know how to survive grub rescue. Don't worry today i'll explaint it out for you.

    Follow these steps to recover Grub:
    Step 1:
    In case, If you have Linux installed in you system but you can't see the Grub because after installing windows it gets disappear. Open you terminal and type this command:
    sudo mount /dev/sdaX /mnt #Replace sdaX with your partition number

    Note: If you don't know your partition then install/open "Gparted" and see your partition numbers. For example see the screenshot below:


    After this follow the step 4 (skip step 2 & 3).

    Step 2:
    If you don't have linux installed now. Means you have completely deleted/removed linux partition. And still you have windows installed but you can't boot it now.

    Then in this case first create a live usb then boot it via recovery mode and select try mode. Like here you can use Try Ubuntu mode.


    Step 3:
    After home screen appears on your desktop just open terminal and follow this command:
    sudo mount /dev/sdaX /mnt #Replace sdaX with your partition number

    Step 4:
    Now type this command: (It will mount all your system files/folders)
    for i in /sys /proc /run /dev; do sudo mount --bind "$i" "/mnt$i"; done

    Step 5:
    Now type this command to open terminal as root:
    sudo chroot /mnt

     Step 6:
    After your opened terminal as root follow these commands simultaneously.
    update-grub
    grub-install /dev/sda
    update-grub
    exit
    sudo reboot

    Now see the magic. Your Grub will appear now and you can boot your desired OS easily. 😙

    In this tutorial we will use Social Engineering tool i.e Credential Harvester attack in kali linux.
    All you need to do is follow the tutorial as it is to see the Credentials Harvester into the action.

    WHAT IS CREDENTIALS HARVESTER ATTACK ?


    It is a part of SOCIAL ENGINEERING TOOLKIT. In this method the attack started with a creation of phishing page. Attacker set the post back ip address to receive the credentials like usernames and passwords. The attacker can shorten the ip address to make the ip address looks like a genuine url. When the victim visits the url and feed the login details, the post back feature of the page will send all the data to attacker.
