<< Solved >> Waiting on IOproviderclass... IOresources... boot-uuid-media

Edit: Fixed. I checked through BIOS settings with a guide for the motherboard, and made a couple of changes to be the same with the guide, and it worked. I have no idea why my earlier settings worked!


My GA-H107N-WIFI had been working flawlessly. It has Big Sur and OC 0.69. Not sure what went wrong, but now it can't boot. I didn't mess around with any settings or perform any updates.

Any clues?

Selecting the Recovery console on OC hangs the system too, but at a different point, I do not see the same error message "Waiting on ... boot-uuid-media".

With another SSD installed with Windows 10, the PC is able to boot into Windows 10, so there's nothing wrong with the hardware.

I moved the affected SSD to another Mac to perform disk repair just in case there were errors. No errors for EFI as well as the main volume.

I also tried someone's working EFI.


Nothing works! Please help, any ideas?
