This is the just another tutorial on BackTrack 5 published on this website. You may read the previous tutorial’s on this distribution’s category
BackTrack is a Linux distribution based on Ubuntu Desktop, but specifically designed and loaded with applications for security and penetration-testing professionals. The latest edition is BackTrack 5 R3. The R is for Revolution.
When attempting to dual-boot a Linux distribution with Windows 7 on a single hard disk drive (HDD), the most important decision you’ll have to make is where to install GRUB, the boot loader on virtually all Linux distributions. By default, the Linux distribution’s installer will want to install it in the HDD’s Master boot Record (MBR). However, doing that overwrites the Windows boot loader, so the recommended location for GRUB when dual-booting with Windows, is the boot or root partition of the Linux installation. That requires creating partitions manually, which is not a difficult task, if you have some knowledge of disk partitioning in Linux. If you don’t, guide to disks and disk partitions in Linux is a highly recommended read.
If you’ve ever attempted to dual-boot BackTrack 5 and Windows by installing the former on partitions that you created manually, you know that the installer will not allow you to install GRUB in the boot partition or any of the partitions used for BackTrack 5.
In this article, you’ll see how to install GRUB in the root partition using a backdoor method. It’s a very simple method that does not require manual disk setup for BackTrack 5. Here are the steps involved:
A. Install Windows 7: If you have an existing installation of Windows 7, then you do not have to reinstall. If you decide to reinstall, you may optionally set aside the disk space that will be used for BackTrack 5. Because this step of the installation process for the system used for this tutorial was done on real hardware, there are no images for show for this step.
B. Install BackTrack 5 R3: There is a GNOME and a KDE version of BackTrack 5. The GNOME version was used for this tutorial, but it does not really matter which version you use. You may download an installation image from here. Burn the downloaded image to a DVD. You will be using one of the installer’s automated partitioning modes to create partitions and install the system. By default, BackTrack’s installer creates two partitions. The first will be mounted at /, and the second for Swap, with GRUB installed in the MBR.
C. Install GRUB in BackTrack’s Root Partition: After the last step, this step calls for installing GRUB in BackTrack’s root partition. When this step is completed, you will have GRUB in two locations – in the MBR, and in the root partition. But this is only temporary, because in the next step, you will be wiping GRUB from the MBR.
D. Reinstall Windows Boot loader in the MBR: After the last step, boot into Windows 7 and reinstall its boot loader in the MBR.
E. Add BackTrack 5 to Windows Boot Menu: Finally, add an entry for BackTrack 5 R3 in Windows 7′s boot menu.
Now that you know what it takes, here’s a step-by-step guide on how I did it, starting from step B.
1. BackTrack 5 Partitioning Methods: Reboot the computer with BackTrack’s installation DVD in the optical drive. At the boot menu, select the default and press the Enter or Return key. By default, BackTrack doe not boot into a graphical desktop. At the command prompt, typing startx will start the GNOME or KDE desktop, depending on the version you are using.
Once in the live desktop, click on the Install BackTrack icon on the desktop to launch the installer. Then click until you get to the step shown in the image below. In the test installation used for this tutorial, I installed a fresh copy of Windows 7, leaving some unallocated space for BackTrack 5. You can see the scheme in the upper green bar. If you do not have the luxury of reinstalling Windows 7, the installer will take care of freeing up space it needs to install the system. That is the default option.
2. Advanced Partitioning Tool: This image is just to show the existing partitioning scheme as seen from the installer’s Advanced Partitioning Tool. You get here by selecting Specify partitions manually (advanced), then clicking Forward in the previous step. You didn’t have to come here, but if you did, click the Back button.
3. Install BackTrack 5: Ok, back to this step, the best option for me was Use the largest continuous free space. By selecting that and clicking Forward, the installer took care of the rest.
4. Installation Summary: But before it starts the actual installation, it will let you know what it will do in the installation summary step. You can see that two partitions will be created, and because they will be created as logical partitions, the device numbers will be sda5 and sda6. The former is the root partition, while the latter is the Swap space. If you want to see where GRUB will be installed, click the Advanced button. When you’ve satisfied your curiosity, click the Install button.
5. Install GRUB: After the installation, and assuming it was successful, rebooting the computer will drop you into your new BackTrack 5 R3 installation. As with the live desktop, it will drop you to a console. Now, you need to login. The default username is root, and the password is toor. Once you are logged in, you may start the graphical desktop by typingstartx.
The task at this step is to install GRUB in the root partition. You need to launch a shell terminal to do that. There’s an icon for it on the top panel. If you do not remember the device number of the root partition, type df -h to see a listing of the partitions on the system. Now that you know what it is, type grub-install /dev/sda5 to install GRUB in its first sector.
After typing that command and pressing the Enter or Return key, the system will inform you that it’s a bad idea to install GRUB anywhere but in the MBR, and will refuse to execute the command. But you can force it. And that’s exactly what you’ll need to do.
6. Force-install GRUB: To install GRUB by force in the root partition, give the last command the – -force switch, so that it becomes grub-install – -force /dev/sda5.
If executed successfully, there should be no errors, which means that you now have GRUB installed in the MBR and in the root partition of BackTrack 5. Reboot the computer. Since you are still at the command line, you can reboot by typingshutdown -r now. At the boot menu, select the Windows 7 entry to boot into Windows 7.
7. Install EasyBCD: Once in Windows 7, you now need to reinstall Windows 7′s boot loader in the MBR, which is the same thing as wiping GRUB from that location. Windows has a command-line for doing it, but EasyBCD is a free, graphical application that makes it very easy. You may download it from here. Install and start it. This is the main interface. Click the BCD Deployment tab.
8. Reinstall Windows Boot Loader in the MBR: In the BCD Deployment, select the highlighted option, then click on theWrite MBR button. After this, exit EasyBCD and reboot the computer, just to make sure that you can reboot into Windows. Note: You will not be able to boot into BackTrack 5, because Windows is now in charge and its boot loader is not ware that Windows 7 is sharing the HDD with another operating system.
9. Add Entry for BackTrack 5: If you managed to reboot into Windows 7, start EasyBCD again, then click on the Add New Entry tab. Select the highlighted options, then click on Add Entry.
10. Preview Windows 7′s Boot Menu: You can see the entries that will be in the boot menu from the Edit Boot Menu tab. You may now close EasyBCD, reboot the computer and test to see if you can boot into both operating systems.
This method worked for me on first try. If you followed the steps as given in this tutorial, it should work for you too.
