Any help on what I can do? restore disk from Time machine copy, or install MacOS on another MBP, or boot from CD/dvd or external HDD and install system to new SSD Thank for the reply.

Once you install all High Sierra updates, the EFI bootrom should be updated automatically if your battery is charged and the charger connected: the Mac will reproduce a long beep and show a gross loading bar. I hope that this helps and best regards from Spain, Alberto M.

Hi there! Your system may need an EFI update to boot from APFS file system. Please boot up with your former macOS Plus file system drive and install the EFI Bootrom update that you can download here:, format the SSD and continue using macOS Plus file system so your Mac will be able to boot. After the bar progresses to 100% its just a white screen. Checked a HDD and a uSB both not detecting.
