Welcome to the world of Linux! This blog will take you on a step-by-step journey on how to get familiar with Linux if you are a new user. By the end, you\'ll have an understanding of Linux and how to use it effectively.
Linux is an open-source operating system that manages your computer\'s hardware and software resources. Unlike proprietary systems like Windows and macOS, Linux is free to use, modify, and distribute. Its open-source nature has created a vibrant community and many different versions of Linux, known as distributions (distros).
Why Use Linux?
Cost-Free: Linux is free to download, use, and modify.
Security: It is known for its strong security features and regular updates.
Flexibility: Highly customizable to fit your specific needs.
Performance: Efficient and can run well on older hardware.
Getting Started with Linux
Ubuntu:Known for its user-friendliness and extensive documentation.
Fedora: Offers cutting-edge features and a strong focus on security.
Debian: Valued for its stability and reliability, especially in server environments.
Kali Linux and Parrot Security OS: Debian-based distros tailored for penetration testing and security research.
Backbox: An Ubuntu-based distribution optimized for security assessments.
Installing Linux
You can install Linux alongside your existing operating system (dual-boot) or as a Virtual Machine on your Host OS (Primary OS) using a Virtualization Software like Virtual box, VMware, Microsoft Hyper-V etc. In order to create and run a Virtual Machine (Guest OS), We need to meet certain technical specification like processor should support Virtualization Technology and it should be enabled (It can be enabled/disabled from BIOS/UEFI settings). Most modern processors support Virtualization. Virtualization allows you to share your system resources (RAM, Storage, Network etc. ) without requiring you to install a completely new OS from scratch, it allows you to run multiple virtual machines. Let us take a look at steps we can follow to create an Ubuntu Virtual Machine using Oracle Virtual Box. You can download VirtualBox installer from VirtualBox.org and follow the installation steps. Once Virtual Box is installed:
Download Ubuntu ISO: Get the desired version from the Ubuntu official website. Many Linux distributions already share their VM editions (You can download the VM version of that OS you are installing, if available)
Enable Virtualization: Restart your PC, while booting up press F2 or F10 enter BIOS/UEFI settings, and enable Intel VT-x or AMD-V. (You can find this information on system manufactures website).
Open VirtualBox, click "New", name the VM, select "Linux" > "Ubuntu", allocate at least 2048 MB RAM (2GB RAM), and create a virtual hard disk of at least 20 GB, you can customise the Allocated RAM and Storage if you have more RAM available or more storage available .
Go to VM Settings > Storage > Controller: IDE > Empty > Choose disk file > Select Ubuntu ISO.
Select the VM and click "Start", then follow on-screen instructions to install Ubuntu.
After installation, remove the ISO from the virtual drive by going to Devices > Optical Drives > Remove disk from virtual drive.
Optional - Install Guest Additions: Guest additions allow user to install device driver |
