thanks, as soon as I return I will start it up and keep you updated, I hope it starts without problems

@Jake Lo ok thank you very much I will do the usb just returning, to be able to enter and modify it manually, the usb must be in fat 32 right? Because before making today's change, I backed up my entire EFI folder so that I could restore it if necessary.

an extra question, how do I get out of the openshell loop to enter the system normally?

thanks brother for answering, I did not choose openshell to restart, just restart to start with part 2 to map and go directly there, restart several times by typing exit; I even pressed f12 to directly choose the boot where it loaded well but nothing else does not enter the system.

Thank you! @Jake Lolook brother, restart the computer and when entering the bios it is fully enabled and still does not work. Do you notice anything unusual about the Wi-Fi connection in the ioreg bro?

Good afternoon again greetings from Mexico. I have finally finished the Dell Latittude E5470 with BigSur 11.3 with OpenCore updated to 0.7.2 At the moment these are the specifications: CPU: Quad core Intel i5-xxxx 2.6GHz RAM: 32GB DDR4-2133 Graphics: integrated Intel HD 520 Storage: 1TB M.2 and 2TB SSDs I have solved many problems thanks to the good @Jake Lo who once helped me to solve a battery and drain problem. I have mounted the m2 SSD and SDD this way in case someone needs to do it on this machine: You completely disassemble the SSD and connect, you can use double-sided tape to join them and they do not move Currently I find myself with 3 problems hoping they can help me solve it. 1.-The integrated web camera does not work I have read that it works for some but I cannot make it work. 2.-I'm browsing quite slow since I updated to OpenCore 0.7.2 (from 0.7.1 to 0.7.2), and I found the surprise that in HackinTool I have the same wifi kext twice and I can't find how to eliminate it, MI THEORY IS THAT BY HAVING IT DOUBLE I AM NAVIGATING VERY SLOWLY even connected to the 5hgz network of my fiber optic modem. 3.-When connecting the hdmi cable the computer turns black and the video does not pass to the external monitor, I have tried everything to close the lid, connect and disconnect the hdmi and only if I run with luck it works and if not I can not do works correctly. 4.-The AirDrop still does not work, which I understand is linked to apple services which apparently I have working at a hundred. Any help would be very much appreciated! I've been working with this team for weeks and the performance is excellent! greetings little brothers !! I am attaching my record in case someone would do me a favor to give you a revised one that does not interfere with your valuable time ** Note If someone needs my configuration and has the same equipment, I can also contribute to the community! hackingt0sh.ioreg
