BIOS Configuration Settings

All recent laptop and desktop computers use either hard disks or solid-state drives (SSDs) that connect 

via SATA ports to the motherboard. SATA drives can be configured in the system BIOS in three ways:

  • IDE
  • AHCI
  • RAID

You will need to switch SATA Controller mode to AHCI in order to proceed with Evren OS installation.


This article below guides us on how to change RAID or IDE Mode to AHCI in BIOS. Before we proceed 

with the steps, the screenshot below explains the difference between the SATA Controller modes.




⚠️  Before you begin, please make sure that you do not have any important data on the laptop/PC 

       you are about to use.
