Notices
• This system is preinstalled with Windows® 7 Professional
operating system (OS) and also comes with a license and media
for Windows® 8.1 OS. You may only use one version of the
Windows® OS at a time. Switching between versions will require
you to uninstall one version and install the other version.
• To enable downgrade to Windows® 7 Professional on this
system, the BIOS settings on this system were changed to boot
into a legacy BIOS mode. If the BIOS setting is not changed to
native UEFI mode boot prior to installing, Windows® 8.1 will
install; however, the following Windows® 8.1 functionality will
not be enabled as they rely on UEFI mode boot:
• Secure Boot
• Seamless Boot experience
• Network unlock for Bitlocker for systems with a Trusted
Platform Module (TPM).
• eDrive support
IMPORTANT!
• Your Mini Desktop PC comes preinstalled with Windows® 7
Professional. Downgrading to Windows® 8.1 deletes all of your
system data on Windows® 7 Professional.
• If your Mini Desktop PC package contents do not include a
Windows® 7 Professional Recovery DVD, ensure that you create a
backup before installing Windows® 8.1.
• For more details about recovering your system in Windows® 8.1,
