When your Mac won't start up, usually, you need to enter macOS Recovery mode and use the macOS Utilities to fix your Mac.
But in macOS Recovery mode, you also find that your internal hard drive not showing up on Mac.
Case 1: Startup disk not showing in the Startup Disk utility
Sometimes, you choose to reselect the startup disk to try to make the Mac bootable again. You select the Apple menu > Startup Disk, only find that the Macintosh HD missing from Startup Disk.
Here are three common reasons and solutions:
1. The internal hard drive is blank

2. The internal hard drive is not mounted in Disk Utility of macOS Recovery mode
Your internal hard drive has some errors, it greyed out in Disk Utility. In other words, it's not mounted, and that's why you can't see it in the Startup Disk window.
To make the internal hard drive mountable and show up again, you can click the Mount button in Disk Utility. If it's in vain, check if your internal hard drive has any errors and repair it with First Aid in Disk Utility.
- Select Disk Utility from the macOS Utilities menu.
- Select the corrupted Mac hard drive from the left-hand panel if you can see it.
- Click First Aid on the top and wait for it to verify and repair errors.

3. The internal hard drive not showing in Disk Utility of macOS Recovery mode
Commonly, the startup disk not showing up in Disk Utility has some hardware issues. In this case, your Mac won't boot and the startup disk can't be found anywhere on Mac, even in Disk Utility.
As the internal HDD cannot be seen in Disk Utility macOS Recovery mode, to make your Mac rebootable, you have to take it to a professional repair store.
Or, there's also another possible situation. The internal hard drive that disappeared from your Mac is an internal Fusion drive.
When an internal Fusion drive is split, you can't see it showing up on Mac normally. Instead, it is split into two separate hard drives: SSD and HDD, making the internal fusion hard drive invisible.
If you can see them with the correct storage capacity by typing the command line diskutil list in the Terminal window, you need to recover data from the split Fusion drive with iBoysoft Data Recovery for Mac to avoid data loss, and then fix a split fusion drive as soon as possible.
To recover data from the split Fusion drive, please run iBoysoft Data Recovery in macOS Recovery mode.
But if you can't see the fusion hard drive with the right disk information, you'd better call 1-800-275-2273(US) or contact Apple for support.
Case 2: The startup disk not showing up when reinstalling macOS
When you prepare to reinstall macOS but find that there's no startup disk on Mac, you are asked to choose the startup disk where you want to store the operating system.
You can open Disk Utility to check if the internal hard drive is partitioned. And if the partition map scheme of the Mac hard drive is GUID Partition Table.
Besides, if a volume is present on the internal hard drive, select and make sure it is in Mac OS Extended (Journaled) format (for macOS 10.13 & previous versions), or in APFS format (for macOS 10.14 & later).
Erase/repartition the drive if needed, and see if that fixes the Mac hard drive not showing up issue.
