It may be starting the shut-down during his choosing an option, I have had a similar problem, and got it to start-up by remembering the exact locations of the options and clicking one each time, as quickly as possible, until it started.
That is if the options are applicable.
I don't think that it would hurt to try this, you need to be pretty quick.
I'm sure there are other metods, but this may be worth a try.
Someone will come along with a different choice that will work if this doesn't.
