How to change BIOS to UEFI?
Hi, a while back I assembled my PC but couldn't turn on the Optane drive. It looks like only half of my storage is available (2TB instead of 4TB). I figured out the issue: I'm not using UEFI mode, which is the only supported setting for Optane, and my drive uses MBR. Now I need to switch to UEFI but I can't find any guidance online. I don’t mind losing data, and my motherboard is a Z370 Aorus Gaming 5 with the newest BIOS. Thanks!
The best approach is to set up the system accurately using UEFI. This involves some effort that might fail if not handled carefully. In technical terms: CSM must only be activated when you have older hardware that doesn’t support UEFI. EFI should remain disabled (often called 'Legacy mode') unless you’re installing Windows Vista or earlier versions, or if Windows 7 encounters problems with your setup. Secure Boot needs activation for Windows 8 or newer, or for Ubuntu with UEFI support, to protect against rootkits that can disguise themselves as the operating system and immediately take control. This ensures full system integrity and prevents unauthorized access.
The motherboard offers both hybrid features. To ensure proper UEFI compatibility, disable the CSM module.
