    So I converted my Mac Mini's HDD to APFS not realising I made a mistake. I followed a tutorial online. I unmounted the disk from the Mac from Disk Utility and from the drop down menus at the top chose "Convert disk to APFS" the conversion seemed to have gone fine and it remounted the disk but when I try to boot the Mac it only boots into Recovery Mode. And when I hold the Option key the only drive I see is the recovery drive. I still see Macintosh HD in the Disk Utility menu but not when I try to boot. Any fixes?

    EDIT: I just had to use the Repair option in Disk Utility. All good now. :)

    the more you try to modify any

    I'd have to agree with Phil above in this matter.

    OP --
    I think your best course of action would be to
    - backup (use CarbonCopyCloner to create an HFS+ backup [not APFS] to an external drive)
    - boot from the bootable CCC HFS+ backup
    - ERASE the internal drive -- NUKE IT BACK TO ZERO (Mac OS extended with journaling enabled, GUID partition format)
    - Restore to HFS+ from the CCC cloned backup.

    CCC is FREE to download and use for 30 days...
