I'm also attaching an image of the machine booting. I ran a blkid there, and I see that the /dev/sd* assignments are completely different. Not sure why

Because /dev nodes are unpredictable. Update your bootloader config+fstab to use UUIDs.

Thanks WorMzy !

It worked as soon as I switched to UUIDs.
