First you'll have to read the OpenCore guide and understand what you are actually doing and what is needed for your Haswell system.I am needing help coming up with the EFI Folder

Okay thanks I meant to delete the DSDT.amlIt's a good start but still needs a lot of work to be complete.
First off, I would use iMac 15,1 instead of 17,1 as you have a Haswell
4790K, the exact same CPU as the iMac 15,1 used.
You don't need the DSDT.aml file when using OpenCore. The guide specifically says that.

When you have the two required .aml files in the ACPI folder, they must be declared in your config.plist.
Here is where they should show up. You could us Proper Tree's snapshot feature to add them.

Also please delete the Warnings 1-4 as they are not needed.
I did do the snapshot. Here is my updated version. Boots past picker to black screen on USB 3.0 port.
Use a USB 2.0 port instead. I don't think you should be using USB injectall kext with Big Sur. Probably don't need AGDPmod=Pikera either. Remove both of those and try again. Always reset NVRAM after making changes.Boots past picker to black screen on USB 3.0 port.
