Problems with the Instalation of Ubuntu (with Dual boot on Windows) on a motherboard Mancer A520M-DX, tried everything, nothing worked.

Understanding and Troubleshooting Ubuntu Dual Boot Installation Challenges on ASUS MANCER A520M-DX Motherboard with Windows

Introduction

Installing a dual-boot system with Ubuntu and Windows can be a rewarding experience, providing flexibility and access to a robust open-source OS alongside familiar Windows environments. However, hardware compatibility issues, BIOS configurations, and partition management can complicate the process. In this article, we will explore common problems encountered during Ubuntu installation on a system equipped with an ASUS MANCER A520M-DX motherboard, based on real-world user experiences, and offer insights into troubleshooting strategies.

Overview of the Installation Scenario

The user purchased a pre-assembled PC with Windows 10 pre-installed, aiming to add Ubuntu 24.02.4 for dual-boot functionality. Initial steps involved creating a bootable USB drive using Rufus, selecting partition schemes, and attempting installation. Despite following standard procedures, the process was hindered by persistent errors and configuration challenges.

Key Challenges Encountered

Partition Scheme and Boot Mode Conflicts
Issue: The user initially selected the MBR partition scheme instead of GPT, leading to installation issues.
Resolution Attempt: Re-creating the bootable USB with correct partition settings; however, problems persisted.
Insight: Modern systems, especially UEFI-based motherboards, typically require GPT partitioning for secure boot compatibility.
Secure Boot and UEFI Compatibility
Issue: Suspected compatibility problems related to Secure Boot settings and UEFI configuration.
Actions Taken: Updating Windows to Windows 11, attempting to disable Secure Boot, adjusting BIOS settings.
Outcome: No resolution achieved; errors continued despite these modifications.
Advice: Ensure Secure Boot is disabled in BIOS when installing Linux distributions, and verify UEFI mode is enabled.
Residual Partitions and Data Cleanup
Issue: Multiple leftover partitions from previous attempts could interfere with installation.
Approach: Manually deleting residual partitions and performing clean partitioning via advanced disk management tools.
Significance: Removing cluttered or conflicting partitions reduces the risk of boot and installation issues.
BIOS Configuration and Boot Mode Settings
Issue: The system detected installation as if it was in Legacy mode, not UEFI.
Action: Disabling Legacy Support and enforcing UEFI-only boot mode.
Persistent Problem: Despite these adjustments, errors remained.
Recommendation: Double-check BIOS settings for “Secure Boot,” “CSM/Legacy Boot,” and ensure the boot priority is correctly set
