Objective:
Successfully replace Linux Mint Cinnamon with Ubuntu 24.04 LTS in UEFI mode, ensuring stable Wi-Fi and browser functionality. Core 1 • 1.1 – Install and configure laptop and PC operating systems
Environment:
Host: Custom desktop "TheBringerofTech"
CPU: Intel Core i7-2600 (x86_64)
RAM: 9.9 GB
GPU: AMD Radeon RX 500 (Polaris 20 XL)
Boot Mode: UEFI (Legacy disabled)
OS Installed: Ubuntu 24.04.3 LTS (64-bit)
Steps Taken:
1) Entered BIOS/UEFI → changed Boot List Option from Legacy to UEFI
2) Adjusted Boot Sequence → set USB Storage Device as first boot option
3) Created a GPT/UEFI bootable USB with Rufus (Ubuntu 24.04.3 LTS)
4) Booted from USB → selected "Try Ubuntu" to confirm hardware compatibility
5) Verified Wi-Fi networks detected and display working with Radeon GPU
6) Ran full install → chose "Erase disk and install Ubuntu" to wipe Mint
7) Installed Google Chrome via .deb package after first boot (with some troubleshooting)
Results:
System boots cleanly into Ubuntu with no Mint/GRUB error codes.
Wi-Fi connection is stable.
Chrome browser installed and running.
TheBringerofTech is ready for lab projects and virtualization.
Lessons Learned:
Correct boot mode (UEFI vs Legacy) and partition scheme (GPT vs MBR) must match for clean installs.
Linux driver issues (Wi-Fi, GPU) often resolve more smoothly with Ubuntu than Mint for modern setups.
Installing .deb packages on Ubuntu differs from Windows — requires either App Center or dpkg.
Next Step Idea:
Install Oracle VirtualBox on Ubuntu, then spin up Windows and Parrot OS VMs to begin virtualization practice (CompTIA A+ Core 1 • 1.2, 1.5).
