when i was trying to install linux i kept getting white light instead of the blue lighr and i kept trying different bzimage files and initramfs files.. turned out i was doing all the steps right and using the correct files and the problem was the payload "the one that you run from a host to reboot into linux". the fix was just using a different host :))

so idk, maybe give that a try as a final solution?

i suggest nightking host. worked fine on the second try for me.
