Live usb does not recognize SSD: should I use AHCI/NVMe?

I just received a new Dell Latitude E5440 running Windows 11. I’m trying to install Ubuntu but since I’m doing this once every ten years I got a new problem every decade. My problem is Ubuntu, on live USB does not recognize the SDD of the laptop.

I fixed the problem myself in the BIOS by disabling RAID. Instead, I checked AHCI/NVMe.

I have a very blur idea of what is RAID. I don’t know what is AHCI/NVMe. I have 3 options is the BIOS in the "SATA/NVMe Operations" panel:

  1. Disabled
  2. AHCI/NVMe
  3. RAID on

Since RAID is not working, it remains 1 and 2. Which one should I use ? AHCI/NVMe is working by the way, the disk is recognized by the live usb.

The fact that it works is basically giving you the answer.

AHCI/NVMe is the native interface for SATA/NVMe devices, and probably what will give you best performance. Simply leave it there.
