Objective (CompTIA Mapping)
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).
