GA-Z170MX-Gaming 5 Sloooooooooow Boot!

[refosk]

OK, I follow these instructions, make uefi usb (http://www.eightforums.com/tutorials/15458-uefi-bootable-usb-flash-drive-create-windows.html) tried with rufus then manually but when windows start install I get message that drivers missing. I create cd with mb_driver_intel_bootdisk_irst_64_100series but didn't help.
When I installed windows 10 UEFI mode everything went well and the boot time problem was also resolved.
So what drivers are missing in my W7 USB bootable flash drive?

You can't use these when installing W7. It has to set to (Default: Other OS) With W7 the only thing that you use is UEFI DVD or USB. I just built 2 computers doing this way with W7 UEFI DVD or USB . 

Windows 8/10 Features
Allows you to select the operating system to be installed. (Default: Other OS)

You want this set to wondows 8/10

CSM Support
Enables or disables UEFI CSM (Compatibility Support Module) to support a legacy PC boot process.
Enabled Enables UEFI CSM. (Default)
Disabled Disables UEFI CSM and supports UEFI BIOS boot process only.
This item is configurable only when Windows 8/10 Features is set to Windows 8/10 or Windows 8/10 WHQL.

Update:
The boot times are an acceptable ~20secs with just an update of the BIOS to F7b.   This is without a UEFI load of Windows 7, only the BIOS update!

I've got the same issue utilizing a Samsung 950 Pro 512 GB with my Gaming 7 MB running Windows 7.   The drive performs great after desktop but takes 1:05 to boot.   The machine just pauses 30 seconds after post.

I've seen a lot of complaints with other NVMe drives and come down to how long it takes to initialize the drives.   If there is a solution, I'd love to hear it.

Can anyone help, I have a SM951 128gb M.2 PCIE drive with clean install windows 10 on it. Also 16gb DDR 4 Corsair ram yet the boot time is 1 min from cold! My old PC was a Phenom II 1045T with 8gb DDR2 and booted in 40s! Have tried everything in the bios unplugging all other drives / set to Ultra fast boot etc nothing brings it down from cold boot. (If I restart from the bios sometimes it boots in 30s missing the black screen / dead space at the beginning but I cant get a quick boot from cold. Very disappointed with this board. Virtually no explanation of what the bios setting actually do in plain English!   A YouTube link below shows what's going on during boot.

Setting it UEFI makes it boot much faster. You have to have the windows disk in the DVD drive or the windows USB plug in. To use UEFI boot device. If you don't have them in either one you can't choose the UEFI device.

I would have to reinstall windows to do it, so I'll just deal with the extra 8 seconds of boot time until I have another reason to reload windows.

I myself I don't really care about boot times. Been doing this far to long to worry about the small stuff. All I care that the computer comes on and it boots into windows other then that no big deal about boot times. lol
