Hello Everyone,
I have already asked this question but I am sending it again since I found more info on this matter.
I have built coreboot with UEFIpayload and Universal Payload but either way grub can't load the OS. I the OS I am trying to boot is Ubuntu 24.02 and it shows the grub menu but hangs when linux kernel is tried to call. below is part of the log I got from the BIOS:

FSOpen: Open '\efi\rufus\ntfs_x64.efi' Success
