Dell latitude 5480: Big Sur installing - EFI folder required

[Alex Kranich]

Hi all,

 

did anybody succeed installating last version of Big Sur on an Dell Latitude 5480?

Mine has:

Skylake i5-6440HQ CPU @2.60GHz

Chipset skylake-H

Intel HD 530 graphics

 

I created my pendrive 64gb usb type-c with Big Sur OS 

 

but I cannot find any way and any correct EFI folder to boot and install with clover and Opencore.

 

could you please help me?

Thank you really for your answer!!

I checked already almost all links and tried several times with all versions of OS (big sur, Catalina for intel etc) but is rebooting saying panic etc.

 

this is the last one which I tried using config ( not 2 or 3 ) as suggested for intel.

nothing . is rebooting saying panic etc.

Thank you really much for your reply @MaLd0n

Do you have the right efi folder for my notebook?

 

latest version of Big Sur in my pendrive is ok, or for my notebook needs to flash another os?

Updated:  i have used this EFI FOLDER 

With Big Sur latest version 11.4

 

Finally booted but I see the first screen, cause mousepad, trackpad and keyboard are not working.

 

could you please fix it?
