W7 + new Asus mobo + UEFI Bios + Safeboot = PROBLEMS!

(Edit: Sorry! Title should read Secure Boot, not Safeboot)
Project: All-new hardware (case, PS, mobo, CPU etc etc) with an NTLite-integrated-update W7 on a flash drive.

Lots of steep learning curves building this W7 + 200 updates flash drive, but that's finally done.

But now I've plugged the flash drive into my shiny new Asus Z170M-Plus motherboard, I've got a whole new set of problems with the UEFI Bios and Safeboot. I think I've solved it, but in the course of several days of head-scratching and research online, I've turned up some interesting information. Anyone seen this website?

Code:

http://dellwindowsreinstallationguide.com/ensure-you-have-the-correct-sata-configuration-in-the-bios-setup-for-your-configuration/uefisecure-boot-disable/

I've trimmed out some irrelevant stuff but, basically the guy says this:

Associated with UEFI is SecureBoot. This is a newer security technologies which only allows 64 Bit code with a Microsoft signature to boot. Codes without such a signature will be rejected and so only only certified code will boot. This makes the boot process secure preventing malicious code from booting. The Microsoft signatures are only present in Windows 8 64 Bit media and later.

In many systems the optical drive (which is falling into obsolescence) will not have the hardware signatures to be enabled as a boot device when secure boot is enabled so I recommend booting exclusively from USB for newer systems.

Windows 7 64 Bit supports the UEFI BIOS and the GPT partition scheme but does not support SecureBoot (which needs to be disabled) for a Windows 7 64 Bit installation. Installation from DVD is not supported and a Bootable USB with appropriate settings must be used.

Windows 7 and 8.1 32 Bit do not support secure boot/UEFI and their installation should be avoided on new hardware.

If I read that correctly, he's saying that:
1) I probably shouldn't be attempting to put W7 on this new machine and
2) The DVD drive won't work under the default UEFI Bios settings, so a flash drive is recommended.

I think he's right about #2 because I tried running a bootable Wipedrive formatting DVD (to make sure the old SATA HDD I'm using as a test bed was clean and unallocated) and absolutely nothing happened. The UEFI bios sees the DVD drive but it won't spin up.

To begin with, I couldn't get the flash drive to boot either, but I think I've solved that (but yet to test it ) by setting 'Secure Boot > OS Type' to 'Other OS' instead of its default 'Windows UEFI mode'.

Anyone had similar issues and solved them?

Hi,
Not sure why you're reading stuff from Dell
All I can say to Dell's statement is Hogwash

You really need to completely fill in your system spec's page with the link above my signature

A new board depending on which one the only entry in the bios that should be checked or verified is that nothing states UEFI only in Boot device control probably listed in Boot CSM.
You might also see if there is a OS Type listing and make sure it is not UEFI Only and either Other or UEFI and Lagacy OPROM this would be eufi compatibility mode.

Secure boot well that can be tested as disabled but mainly CSM has to be enabled which on some boards might be a version of secure boot which even my board secure boot is enabled and I never had to disable it to install windows from disk or usb device

Any issues could be the usb device.
Disk should have no issues at all installing as long as uefi only is not enabled.

Installing win-7 with uefi is over rated and pretty unnecessary you don't need 2 useless system reserved partitions most people install windows with just the C drive and nothing else in front of it
The eufi install is only good for using bitlocker and that is it which you could not pay to have that junkware enabled.

Thanks. The only relevant system specs at this stage of a non-completed build are:
Motherboard - Asus Z170M-Plus (as I said above)
Processor - Intel i5
Ram - 16GB
Flash drive: USB 2.0 Lexar 8GB

I'm not sure what you said in paragraph 3. Are you saying that the Boot section of the UEFI Bios should NOT say UEFI only?
It doesn't.

And the OS type listing. As I said, I have it set at 'Other'.

I'm not sure what you mean by "Installing win-7 with uefi is over rated" Are you referring to GPT? GUID Partition Table? Surely, anything that takes place in a system with a UEFI Bios has to have a relationship with UEFI.

Please enlighten me.

A traditional uefi install has at least 1-100mb or possibly 2 other partitions besides C drive

There was a report of z170 boards not having usb device enabled so that also should be verified as not being disabled
