I am trying to reinstall MacOS High Sierra but I get an error message unable to upload as lost preboot volume for APFS install, do any of you know how I can sort this out?

How to download macOS High Sierra
Install El Capitan or Later from Scratch
If possible backup your files.
This will install the version of OS X you had installed.
My guess is you will have to create a bootable installer, boot from it and use it to install High Sierra to your internal drive.
