Does Windows 7 support a secure boot in UEFI Windows 8 Linux Ubuntu version 14?

Windows 7 does not natively support Secure Boot, as this feature was introduced with Windows 8. However, UEFI firmware can be configured to allow booting Windows 7, but it will not utilize Secure Boot. As for Linux distributions like Ubuntu 14, they have added support for Secure Boot in later versions, but earlier versions, including Ubuntu 14, may not be fully compatible with Secure Boot without additional configuration.
