Remove Coreboot from Librem 13 version 2

Hi,

I recently upgraded my Librem 13 version 2 laptop and I want to remove everything from my old one so I can try and sell it. I have coreboot currently installed but I think I’d prefer to revert the bootloader to normal and reinstall Pure OS for easier resale so I’ don’t have to try and explain how the Librem key works etc. Whoever buys it wouldn’t want a key with my GPG keys on it anyway I presume.

What is the process to revert the bootloader to normal?

Thanks in advance

You want to revert to coreboot or proprietary BIOS?

If you have PureBoot and wish to revert to plain coreboot: https://docs.puri.sm/PureBoot/GettingStarted.html#reverting-to-the-non-pureboot-coreboot-bios
