My USB won't boot

So , I'm new to hackintoshing and I am following the OpenCore guide and when I try to boot it gives me these 2 error messages which I can't find on Google .

BS: Failed to locate valid OpenCore image -0! BS: Failed to load OpenCore from disk - Not Found

I'm doing this hackentosh on a Dell Vostro 3950 with an i7 10510U ,Radeon 610 mobile Qualcomm QVA9377 802.11ac Wireless Adapter, Realtek PCIe GbE Family Controller (Ethernet).

Of there is anything that I missed let me know

Thank you in advance.
