So i wanted to downgrade my hackintosh from monterey to big sur, so i returned to windows and formatted the USB and the SSD macos was on. I flashed macos big sur and the EFI files to the USB, but I dont see the correct EFI partition USB in the boot menu, I see Windows boot manager and opencore, and when I click opencore, it sends me to Windows. The USB Usually shows as "UEFI: USB". When I choose the original name of the USB (LEXAR FLASH DRIVE 16GB) it says "Insert a bootable USB and reboot, or press a key to try again" or something like that. It will only work if I choose "UEFI: USB" Which does not show up. Weird because this worked with Monterey, until I formatted the ssd and usb. I tried doing Monterey again, same issue. I can't get rid of this stupid OpenCore boot option, I even used the tool in cmd. No luck. Someone please help this is driving me insane.
If you were wondering why I wanted to use big sur, it's because I figured it would be more stable than Monterey. Monterey was smooth, but still decently laggy. I figured big sur would be more stable, as it was released during that "Intel to apple silicon" era of Mac's.
Things I've tried: BIOS update CMOS clear Using Clover instead of OpenCore bcdedit in CMD I am using a Gigabyte motherboard from 2012. I have Vd-t enabled, I tried again form scratch with it disabled, but no luck Virtualization is on AHCI is on Pretty much all my settings are fine. I am not using Ventura or above because those will be unstable, I do not have the sufficient USB drive storage, and Ventura did not install when I tried it. I want to use Monterey and under and I am fine with returning to Monterey.
