Thank you very much!!! It's working now. Just wondering if there is good site to learn how to compile DSDT.I tried to follow the one from Rehabman but can't figure out how to fix the errors when compiling. Again my sincere gratitude for all the help.

Thanks for the response. Unfortunately, same problem still exists. I followed everything from the link you sent. Attached is a screenshot of my BIOS setting. As you requested, I also attached a copy of the BIOS ACPI tables. I am also currently using the latest BIOS version from my notebook. DSDT.zip

The boot pack is from https://osxlatitude.com/applications/core/interface/file/attachment.php?id=12523 which is only for Sierra because that's "latest" available boot pack.

Thank you for the response. I attached a copy my USB Installer EFI folder and a screenshot of the installer when it boots. I also tried using Clover version 5120 to check if it would fix the problem. EFI.zip

Good day. My system is as follows: Dell Inspiron 5548 Intel i5 CPU Intel HD Graphics 5500 8 GB Ram 1 TB hard drive I read the link below to help me install Catalina 10.15.7 in the aforementioned system. But every time that I tried to boot to the usb installer, there is always an error. I already tried uploading all the kexts in the boot pack. I am using Clover 5107 to make the USB bootable and have followed all the instructions from the link. I would really appreciate any help that I could get. Thank you.
