Bootx64.efi not working from EFI

I have followed this tutorial to dual boot my Windows 11 because I have done dual booting before from USB (which doesn’t mean I am good at this), I just wanna learn how to do this without an external drive of any kind. Everything went right until selecting boot the EFI from the boot menu, I can see the bootx64.efi under the UUI partition there but after selecting it goes to Windows instead of the Ubuntu installer. I am using an HP Victus Laptop and have disabled secure boot and can’t find any legacy options in the bios.
