[Clover] Crash just as macOS Sierra installation% reaches end (console error log)

Trying to install Sierra with Clover via USB on a legacy (BIOS) motherboard. I finally made it to the part where it says it's installing on disk "Mac". It takes what feels like 3-4x longer than the estimated time it says (this is on an SSD) and right at the end, the estimation text suddenly jumps from "15 seconds remaining" or something to to "-405 seconds remaining" and a few seconds after that the system reboots. But not before showing the follow text in a console:

NOTE: Yes I do have HFSPlus.efi, inside the drivers64 folder only, not the other drivers folders. It shouldn't be reading from there anyway though as I'm regular BIOS, right?

...help? :(
