To ensure “Boot Settings” and “SATA Operation” are properly configured, restart or turn on your computer. Repeatedly tap the “F2” key at the Dell logo screen to access BIOS. The following steps will differ based on when your system was manufactured. For systems manufactured before 2021, select “Load Defaults” and click “OK.” Click on “Exit” and then “Yes” to save changes. Once again, repeatedly tap the “F2” key at the Dell logo screen.
In BIOS, expand the “General” section and select “Boot Sequence.” Make sure “UEFI” is selected as the “Boot List Option,” and your hard drive is set as the first boot priority. Go to “Advanced Boot Option” and check the box next to “Enable Legacy Option ROMs.” Then, expand the “System Configuration” section and go to “SATA Operation.” Make sure “SATA Operation” is set to “RAID On” for Intel RAID, Software RAID, or “AHCI” for Intel/PERC/LSI/RAID. Expand the “Secure Boot” section.
Go to “System Information” and make sure “Secure Boot Enable” is disabled. In “Boot Sequence” under “Expert Key Management,” disable “Enable Custom Mode.” Click on “Exit” and then “Yes” to save changes. For systems manufactured after 2021, select “LOAD DEFAULTS” and click “OK.” When the computer restarts, repeatedly tap the “F2” key to access BIOS. Go to the “Boot Configuration” section and make sure the “Boot Sequence” option is set as “UEFI.”
Select the “Storage” section and make sure “SATA/NVMe Operation” is set to “RAID On” for RAID functions with VMD Controller or “AHCI” for AHCI/NVMe mode. Back in the “Boot Configuration” section, disable “Enable Secure Boot.” Scroll down to “Expert Key Management” and disable “Enable Custom Mode.” Click on “APPLY CHANGES” and then “Exit.” If you have any questions about this process, contact us via one of the options on our support website.
