I can't understand your problem description, sorry.

This makes no sense to me.

But that's the actual situation: there is only one boot count.
Please keep in mind that this variable holds the number of boot
attepmts since the last power-on that failed to successfully reach a
specific "confirmation point" in your application (that, which is
considered a complete, successfull boot of the whole system).

For this single task there can be only a single counter, or?

I do not see any practical use yet...
