Yes, you got it. There should be only one folder named EFI and it should be at the root level.

Ok, then i really don't know why it's not working

Your EFI folder is correctly configured so let's check some other factors:

• In Boot section of BIOS, is CFG-Lock disabled? It needs to be disabled.
• In BIOS, is VT-d enabled? It should be enabled.
• When you boot the computer, are you pressing and holding F12 to open the BIOS boot menu? Then you're selecting the USB install disk?
• Does OpenCore boot picker appear?
  • If it does, press and release CMD-V to toggle verbose mode on.
  • Then select Install macOS to begin installation.
  • If the install process hangs, what do you see on screen?

-CFG-Lock is disabled
-VT-d is enabled

Im pressing F12 and there are two versions of my Flashdrive:

-Samsung Flash drive 1100
-UEFI: Samsung Flash Drive 1100, Partition 1

When i boot from one of those, the screen goes black for 1 second and straight back to the BIOS boot menu.

Update: When i boot from Partition 1, this appears:

UPDATE: Just try Reset NVRAM as stated below and ignore items 1 through 3 for now. The "OCS Schema" warnings can be ignored. Once you upgrade to OpenCore 0.8.0 those warnings will disappear.

1. Which version of OpenCore Configurator are you using?
2. Which version of OpenCore is shown in the Title Bar of OpenCore Configurator?
3. Which version of OpenCore are you actually using? Because the date of OpenCore.efi is February 2022, it means you're using OpenCore version 0.7.8 (click here).

Finally, at OpenCore boot menu press spacebar to reveal extra options then choose Reset NVRAM, which will be the rightmost option. When system reboots automatically, try selecting Install macOS again.

One quick thing to try is enabling the following, then reboot and see if it makes any difference:

I tried it and the problem remains.
Also:
1)i'm on Monterey 12.3.1 and i deleted the SmallTree-Intel-211-82576 kext and removed it from the config.plist but the problem also remains when i tried to use the i211 ethernet (black screen and reboot).
2)I also have Linux as a boot should i enable OpenLinuxBoot.efi or make any other changes for some reason?
