Recovering Ubuntu/Linux After Installing Windows

Restore GRUB2 after installing Windows

How I Restored GRUB2 after a Windows 7 Install. GRUB2 (Grand Unified Bootloader)  is a universal bootloader used by Ubuntu and other Linux Distributions. If you have a Linux Distribution installed on a partition, and attempt to  install Windows alongside it, your GRUB bootloader will be overwritten by the Windows bootloader, and your computer will only boot into Windows.

Recovering the GRUB2 Bootloader after a Windows Install  is simple. When finished, your Bootloader should detect all installed Operating Systems and automatically add a bootable menu item for each of them.

Lost Linux password ? Reset it !

Have you ever been in a situation where you have lost your password and need to reset it as you want your files badly,You can easily reset passwords, though you must be careful. If a user has an encrypted home directory, you must not change the password this way! This will make all encrypted files inaccessible. You can only use this method on user that doesn’t have an encrypted home directory.

Steps:

1. Get the GRUB menu to show. It is shown by default if you have multiple OS installed, else please hold shift key down during booting to get the GRUB menu to show.

2. In the GRUB menu, highlight the OS you want to boot (if only one is installed, it is already highlighted). Then press the “e” key to edit the boot parameters.

3. Move your cursor to the end of the line similar to:

Code:
linux /boot/vmlinuz-3.2.0-23-generic root=UUID=b8080487-b557-4f55-b288-d7ef2c2b9cc1 ro   quiet splash $vt_handoff

and replace $vt_handoff with init=/bin/bash. So that it reads:

Code:
linux /boot/vmlinuz-3.2.0-23-generic root=UUID=b8080487-b557-4f55-b288-d7ef2c2b9cc1 ro   quiet splash init=/bin/bash

then press F10 to continue the boot.

4. After a little while, and some error messages you can ignore, you are now logged in on the root console without having had to enter a password. Next, run the following command to remount the / partition so you can write changes to it:

Code:
mount -o remount,rw /

5. Finally, run the following command for each user (without an encrypted home directory!) that you want to give a new password. Replace “username” with the name of the user.

Code:
passwd username

6. Then sync the file system so all changes are written to disk, and reboot:

Code:
sync
reboot -f

And, to be clear, once you have rebooted you need to login as an admin user to make changes to the system (somebody member of the sudo group). And you confirm where need with the admin’s own personal password. A standard user (not a member of the sudo group) is not allowed to make changes to the system.

Ethical Hacking

Introduction to Ethical Hacking
In This Chapter
Understanding hacker objectives
Outlining the differences between ethical hackers and malicious hackers
Examining how the ethical hacking process has come about
Understanding the dangers that your computer systems face
Starting the ethical hacking process
This book is about hacking ethically — the science of testing your computers
and network for security vulnerabilities and plugging the holes you
find before the bad guys get a chance to exploit them.
Although ethical is an often overused and misunderstood word, the Merriam-
Webster dictionary defines ethical perfectly for the context of this book and
the professional security testing techniques that I cover — that is, conforming
to accepted professional standards of conduct. IT practitioners are obligated to
perform all the tests covered in this book aboveboard and only after permission
has been obtained by the owner(s) of the systems — hence the disclaimer
in the introduction.
