It works fine like that, I did it yesterday myself with the last Rufus and Win 10 x64 2004/consumer. It just quips about Secure Boot. On my Z370 motherboard I can boot with Safe Boot and non-CSM UEFI-only modes enabled by the way. There should be 2 partitions on the USB when you press F11 or whatever your mobo vendor uses. One of them can boot properly and you'll just be able to install as UEFI+SB.
Rufus is one of the most used tools to create bootable usb stick. you created a uefi bootable iso through rufus so you must go to bios and enable UEFI so that the usb can boot. i suspect you 're trying to boot the usb with legacy bios enabled.
That worked. Rufus created 2 partitions on USB, I suspect the it's because MSDN images are still new and support needs to be added.
Your screenshot shows nothing wrong, it's just a warning to turn off secureboot before you boot from the USB.
It's working with Rufus. It says you must disable secure boot in bios while you install Windows. Then you can reenable secure boot in bios.
Why using 3rd party tools when MDL solutions exist (ie https://forums.mydigitallife.net/th...with-secure-boot-install-wim-over-4-gb.79268/)?
Anybody simply use Diskpart ? Formatted to NTFS then use Code: bootsect /nt60 f: f being the USB drive letter Then simply copy the files to the USB, even with a large install.wim I have tested this on Z97 and Z170 and Z270 boards set to Secure Boot. USB boots UEFI. Not working on Z77.
