In short, I am completely unable to boot kernel 4.12-rc3, even though I could boot from 4.12-rc2 perfectly fine. The loading screen does not appear at all, instead GRUB remains stuck on "Loading initial ramdisk ...". Please help. I don't know how to identify what is wrong because I am completely unable to boot the OS to begin with. Needless to say, this is a major problem.
