unfortunately system does not give any indication like CTRL-D when starting.
I suspect, that it is necessary to press something on the keyboard at this moment (for example shift or something else).

 
at boot hit the enter key. Next prompt is [ctrl-d] or enter root password.

first of all, I see smth like this:
Boot
:
i'm hit enter, system loading, but i'm doesn't see the next prompt. there is no next prompt!!! the next is
Login:
 
OK. What version? (as root uname -X) If this is 3.2v4.2 I suspect that the full utility set may not be installed. But I haven't seen this behaviour.
There are lots of versions based on 3.2, so it may be something I've not worked with.

Is there an entry like this in /etc/inittab:
is:2:initdefault:
If yes, replace the 2 by an S.

Hope This Help

In 4.2 commenting out this line (# in front) forces a choice at bootup.
Once you are in as root /etc/init 1 forces a shutdown and reboot to single or multi (choice at beginning) a parallel of the ctrl-d or password in a normal cold boot.

But since your normal boot is different there is no telling what the actions will be.

Try checking the '/etc/default/boot' table for an entry of 'TIMEOUT'. If there is one there and it has a value, it will affect the wait time at the 'cntl-d' prompt.

The default timeout is 60 seconds before autoboot kicks in, but if TIMEOUT is set to say 1, then the prompt will come and go before you have a chance to respond. It will just automatically start the multi-user load. Set this to a minimum of 20 - 30 seconds, and you'll have a chance at single user.

Worth a look anyway.

'man boot' from the command prompt for a further explanation.
