How to make a bootable UEFI flash drive?

Question

BIOS

There is a computer with UEFI instead of the usual BIOS. The task is to make the computer automatically boot from the flash drive. UEFI allows you to boot from a flash drive formatted as bootable, but does not allow you to select it as bootable by default.
Those. in the boot menu with a flash drive inserted, among other things, the following items are present:
1. UEFI Transcend Flash Drive 4.0 Gb - if you select this item, the download does not work
2. Transcend Flash Drive 4.0 Gb - if you select this item, the download works
A in the menu boot order selection, you can only select UEFI Transcend Flash Drive 4.0 Gb .
As I understand it, you need to somehow make the flash drive a UEFI device, but I could not google how to do it.
Z.Y. The flash drive itself contains the Windows 7 bootloader.

For example, you can do it like this - goo.gl/CxOOy
You didn't write under what OS, etc.

Answer 2

Look,
in the world of UEFI, if you read the big and fat Talmuds , there are TWO types of boot:
1) UEFI boot
2) Legacy boot.
The second type of boot is necessary for the compatibility of bootloaders that do not know anything about PEI, DXE, BDS and other things from the UEFI world.
If your bootloader is Legacy - you need to select Legasy boot, if your bootloader is UEFI - then you need to select UEFI boot.
Judging by what you described , you have a Legacy bootloader .
At the expense of your computer - by any chance, is there an ASUS bios there?
If ASUS - then your problem, at least for now, cannot be solved, because. in their bios cant in the menu. Take my word for it, I spent a year programming UEFI drivers at work.
This is a bug in all asus bios lines and they somehow do not solve it very actively. I myself encountered six months ago ...
I advise you to change the bootloader from Legacy to UEFI.

You can also try updating the UEFI on the motherboard.
