Vostro 3560 Win 7 x64 USB UEFI boot
Latest A13 BIOS (so there is nothing more to update)
Win7 x64 USB installation disk created for UEFI install as per:

Win7 does indeed start booting from the USB in UEFI mode, but it just hangs very early on while still on Starting Windows
It could be even @ Sub phase 1 - PreSMSS: Kernel Initialization
as per http://social.technet.microsoft.com/wiki/contents/articles/11341.the-windows-7-boot-process-sbsl.aspx
Anybody could test it? Anybody has any solution?

After hours of testing it turn out that the F2 BIOS settings need to be set NOT only to UEFI, but also "Load legacy option ROM" for W7 x64 to DVD/USB install boot, but also for Windows load once installed on GPT disk in UEFI mode
Really bad BIOS

I have also tested original Win 7 x64 DVD and sadly this unit does NOT boot either (hangs in same place)
That is very sad, as it is factory supplied unit with Windows 7 (ofcourse in BIOS mode)
Maybe Dell also could not get it working in UEFI mode?
Obviously problem with BIOS IMO

For Win 7 to boot in UEFI mode I had to enable Legacy mode in BIOS, this way it boots fine from UEFI

Doesn't sound like these solutions lead to a true UEFI boot Windows 7 environment. Y'all do realize that turning legacy mode on is basically re-enabling the BIOS, right? So then, why even turn UEFI on at all?

^^Don't listen to anything I said about that. I just had to do this, and was able to determine that OS still boots EFI on GPT disks this way, as long as you format your HD correctly to GPT!
