Do you have a UEFI Setting OS Optimised Defaults?
If so, then, it should be set to Disabled.

OS Optimised Defaults is Disabled.. Nothing.

That's a pity.
There must be something that's preventing your PC from booting the USB?

Do you boot the USB in UEFI mode?

Out of curiosity, it would be helpful if you could verify that the USB installer is in good order?
Have you managed to boot your USB on another PC?

Hi,
Yes - I boot in UEFI.
I select the USB from the boot startup menu.
Yes - I managed to boot your USB on another PC.
I can't figure it

Since allowing USB boot is not Secure, you may also have UEFI settings to allow USB boot or full USB support?
You need to download manual and review settings. The short explanation inside UEFI does not always fully explain everything.

Yes, agreed.
It is essential that all PC owners fully understand the UEFI Settings.

This thread concerning the prevention of booting a USB device is troubling.
For example, if Windows 10/11 crashes and then requires a repair via USB.
The owner discovers that it is impossible to boot an external device?
What do you do?

Anyway, I would encourage the OP to search the UEFI settings for Hardware/Devices to see if there is another setting to manipulate.
Failing that, search the Lenovo support forums and/or contact Lenovo direct.

There has to be a solution.
Or the hardware is faulty?

I've never seen one this hard, I've been lucky I guess with:

Attach the USB device to the system via any available USB port.
Press and hold the Power Button for few seconds to turn off the system completely.
Note: For Windows 8/8.1/10, restart the system before using the following steps.
Power on the system. Press F12 immediately as the Thinkpad logo appears.
There should be a pop-up menu with a list of choices. Select the USB drive using the arrow key and press Enter.
The system should now boot from the USB drive.
Otherwise I'd check the system hardware.
