After N failing attempts to boot image 1 you switch to image 2.

Actually you will have 3 of these.

I told you before that I consider this approach screwed.

I've sent a few replies in the past; I have little or nothing new to

Do not follow where the path may lead....go instead where there is no
path and leave a trail.
