Wintousb 3.4 skip partitioning scheme option

[bbyunzone]

I have a Samsung Portable SSD T3 250GB, and having issue when trying to install Windows 10 on it from a Windows ISO.

My current OS is Windows 10.
The version of WinToUSB is: 3.4

This is the instructions I am trying to follow:

In step 7 it said:
"After you select the USB drive, a pop-up will appear asking you if you want to format it to continue, tick the "MBR for BIOS and UEFI" checkbox, then click "Yes"."


But I don't see the "partitioning scheme option" pop-up:



Instead it skip to step 9:

(The below image is from the original instructions, the image I see is without the little boot partitions on the right.)


Even the installation was successful but without create any boot partition.

Thanks!
