Try manually specifying the root fs and the fs type in the kernel 
arguments. Here, I use:

   root=PARTUUID=the-partition-uuid-of-the-root-fs ro rootfstype=ext4

You can see the UUIDs of your partitions with:

   ls -l /dev/disk/by-partuuid

I always had to do that here, otherwise I just get the same boot error 
as you.
