The most common reason is a corrupted or wrongly formatted partition, but it can also be due to outdated firmware or disk permission issues. In this article, we will discuss different ways to solve this error.
1. Format Disk to APFS
Formatting the disk to APFS makes it compatible with macOS installation, as APFS allows for a preboot volume needed to boot. This step erases all data and fixes partition errors, giving a fresh start for the installer to run smoothly. Note: Formatting your disk will erase all data on it, so we recommend backing up any important data before proceeding.
2. Mount Existing Preboot and Recovery Volumes
Fixing the problem often begins by checking system volumes that were missed. Mounting the existing Preboot and Recovery volumes lets the installer access important files needed for APFS settings. This step links the macOS installer to the current setup, which might avoid creating new volumes and solve the issue quickly.
3. Format Disk to MacOS Extended
Changing the disk format to MacOS Extended (Journaled) wipes away the troublesome APFS setup that often causes errors. This lets the installer correctly switch the disk to APFS during installation, fixing any issues with partitioning or preboot volume setup.
4. Reinstall MacOS in Recovery
Reinstalling macOS through Recovery mode guarantees the system can rebuild the needed APFS preboot volume without issues from previous errors or corruption. This approach skips problematic settings, letting the installer correctly format the drive and set up the needed system files.
