This error means that the Preboot Execution Environment (PXE) cannot be installed on the APFS volume. The main reason that you cannot install the preboot is caused by something (that Apple hasn’t figured it out yet) wrong with the APFS or Apple File System, the new file system that Apple is introducing in High Sierra to replace the 20-year-old file system or HFS+.
The new system APFS has improved the security also it is faster and more compatible with SSD, but the problem occurs with the OS X that is not compatible to it and also with macOS that is older than High Sierra. And when you are trying to reinstall the High Sierra using Recovery Mode, it doesn’t work because of the Apple File System partition type.
