Then your data is most likely gone for good. You should not attempt to format a rotational hard drive as apfs. ESPECIALLY your boot drive.

Use recovery mode to try and reinstall macOS. If you can't get it bootable by reinstalling over itself, you're going to have to reformat the drive and re-install macOS from scratch.

I hope you have a backup...

How did you "change" to apfs? What kind of drive is it? (SSD, rotational hard drive, fusion drive? internal or external?)

When you upgrade to High Sierra, if you have a compatible SSD, it will automatically be updated to apfs. You should NOT manually attempt to convert a boot drive to apfs.
