Why is the bootable USB flash drive not displayed in boot priority?

Question

Why is the bootable USB flash drive with Windows 10 (*64) not displayed in boot priority (asus fx506l laptop)?
The official Window 10 was downloaded via MediaCreationTool21H2 and a bootable flash drive was created (kinqston dt101 g2), FAT 32 format.
And then the problems started: the laptop sees the flash drive, but refuses to put it in the boot priority list.

Secure Boot - disabled
Fast Boot - disabled the
line with the CSM function in the UEFI boot partition is simply missing.
I checked the BIOS version - it costs 309

The boot priority itself is empty, there are simply no devices to launch it.

I tried to create a bootable USB flash drive via Rufus (3.17.1846) by downloading the iso image from the official Windows website - the problem is the same.

Replacing the flash drive also did not help, from which I conclude that the problem is not in the media.

Answer 1

Disable ueffi, secure boot And everything connected with it, burn the flash drive with Rufus in ntfs and MBR format, it should work

Answer 2

And on F8 after turning on what is displayed in the menu?
There may also be an option in bios to support usb boot and in what mode (legacy / uefi).

Answer 3

Flash drives are made for MBR and UEFI, and they are different. In the BIOS of the computer, the boot priority must match the flash drive. For example, a Legacy-booted computer will not see a UEFI flash drive. Some modern laptops only boot in UEFI mode. To create a flash drive, I advise Rufus or Ventoy.

Answer 4

Modern laptops only work in UEFI. When writing the image, select UEFI - and should see.

Answer 5

To solve it, it was necessary to replace the USB flash drive with USB 3.0 and take iso from torrents (I took the assembly for 2020)
