Symptoms
BIOS must be updated or is unable to boot using RAID On mode for Serial ATA (SATA) Operation.
Cause
Linux does not natively support SATA Operation in RAID On mode as of May 2022.
Resolution
To apply the recommended BIOS settings to your Dell computer with a Linux operating system, do the following:
Power off the computer.Power the computer on and quickly press the F2 button until you see the BIOS setting menu.Under the General section, Boot Sequence, check that the dot is selected for Unified Extensible Firmware Interface (UEFI).Under the System Configuration section, SATA Operation, check that the dot is selected for Advanced Host Controller Interface (AHCI).Under the Secure Boot section, Secure Boot Enable, check that the dot is selected for Disabled.Click the Apply button on the bottom-right and then the Exit button.
Note:
BIOS setting locations vary by model.Secure boot may need to be disabled for systems prior to Ubuntu 20.04 to resolve wireless issues.
For newer models, the BIOS settings referenced above are located in the following locations:
Under the Boot Configuration section, check that Boot Mode has UEFI selected.
Note: Most newer models show "UEFI only" because the platform does not support Legacy Boot mode.
Under Storage, SATA/NVMe Operation, check that AHCI/NVMe is selected.Under Boot Configuration, Secure Boot, Enable Secure Boot, check that this is set to OFF.Click the Apply Changes button at the bottom and then the Exit button.
