Windows 7: UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with

Sony claims using UEFI mode to install Windows 7 isn't supported. I'm guessing that's BS, but I am still having trouble doing it. When I get to the Starting Windows screen and the coming together of the Windows logo, the screen freezes before the logo's four pieces come together and it stays that way.

It shall be possible for a physically present user to use the Custom Mode firmware setup option to modify the contents of the Secure Boot signature databases and the PK. This may be implemented by simply providing the option to clear all Secure Boot databases (PK, KEK, db, dbx), which puts the system into setup mode.

If the user ends up deleting the PK then, upon exiting the Custom Mode firmware setup, the system is operating in Setup Mode with SecureBoot turned off.

The firmware setup shall indicate if Secure Boot is turned on, and if it is operated in Standard or Custom Mode. The firmware setup must provide an option to return from Custom to Standard Mode which restores the factory defaults. On an ARM system, it is forbidden to enable Custom Mode. Only Standard Mode may be enabled.
