UEFI BIOS Settings which need to be altered for Windows Installation

The SATA operation should be modified to suit your SSD/HDD configurations, such as SSD cache drive or SSD boot drive or just a conventional HDD.

SecureBoot/UEFI are newer security technologies which make the legacy MBR obsolete.

Sometimes users will want to install 32 Bit versions of Windows and may need to disable these settings. These settings must be enabled for installation on a 3 TB drive or superior.

This setting disables USB 3.0 functionality making USB ports exhibit USB 2.0 functionality. This setting is useful as Windows 7 and earlier versions of Windows do not include native driver support for USB 3.0 and installation using the use of USB 3.0 ports can hence be stalled. USB Debug should be disabled after successful Windows 7 installation and driver installation.

Other UEFI BIOS Settings

Toggles the default between function keys and multimedia keys depending on your preference.

Disabling the onboard LAN controller, loading Windows and then re-enabling it and loading Windows often fixes LAN problems. If the LAN still does not show in Device Manager after this procedure than the NIC has failed.

    1. How did you install Windows 10 and how did you make Windows 10 Installation Media. Please post on the Dell Community Forums – Microsoft OS Forum as its hard to address complicated questions which should be forum threads in these comments.
