Installs Fine, Restart = "Boot Failed"

Software PureOS
1

Please Help with PureOS install:
Installed via balenaEtcher using a clean thumb drive yesterday using whatever version 9.0 is from PureOS.net

  1. No problem installing.

  2. Went online but only by cable. Wi-fi is NOT today’ issue.

  3. Shutdown and after rebooted to:
    “boot failed… boot failed … boot failed.”
    Leaves me looking at "CLIENT MAC ADDRESS: YADDA YADDA (Great tool for finding MAC but it doesn’t say if it’s the GPU, CPU, APU or MBo MAC - doesn’t matter.

  4. Yes - I told it to use the HDD, not the thumb to install to.

  5. I have repeated the install 6 times now, and each time I shut down or let it sleep, restart brings up a “Boot failed”

Ideas are welcomed…

My rig exceeds the minimum with dual ore i5, 300G drive, 6G RAM, clean HDD that had Ubuntu 16.04 on it.

CONCLUSION:
Oattions OK, installs OK, runs OK, but when it Sleeps, or is shut down, it always comes back with “Boot failed”.
