Boots just fine. Can not install new image.

[willpine]

Boots and runs just fine, however the Linux Mate is a little heavy, runs slow, bogs down etc. I wanted to try a lighter O.S. I have three SD cards, used three installer types including the Etcher remix made for Pine64. Once I install the image on the SD card/s it will not boot. The power button symbol just flashes until I remove the card, then it continues to boot just fine into Mate. I have used all three of these sd cards to boot a live image of the android-for-pine but that too was sluggish and unresponsive.

TL;DR SDCards I have worked previously, they do not work when I image DietPi.

Is there a preboot screen, verbose, or a bios type screen to monitor the boot process?

This unit came pre-flashed from the factory.
