On this laptop I get something with a similar flavor.
However, it stays on the screen long enough that I can see that a 
specific option has been asked for but is not available. I've not 
investigated further as it occurs only on this physical machine 
otherwise continues normally.

I frequently get that on the *FIRST* boot on a fresh system.
It is looking for the SWAP partition.
The cause, in my case, is two fold.

I experiment multiple configurations on my machine.
For my use case the Debian installer has two annoying "features".
I explicitly say "features" because, all though it bugs me [pun 
intended], I believe it is intentional and what a TYPICAL user 
wants/expects.
1. If installer installs grub to boot partition it always gives priority
   to the most recent install. *NOT* desirable when experimenting ;}
2. If you want a swap partition used, there appears to be noway of using
   the existing SWAP without changing its UUID - thus breaking all other
   installs :<

My procedure after an experimental install is:
1. Run update-grub from my default install.
2. Edit etc/fstab to point to the same swap partition that all other
  installs use.

YMMV
