Otherwise, you can only rely on third-party Mac data recovery software - EaseUS Data Recovery Wizard for Mac to recover missing files.
This professional and trusted data recovery software can help you transfer files in macOS Recovery mode when your Mac startup disk has disappeared.

Note: If the Terminal displays either "No such file or directory" or "Could not resolve host," you should verify that the command line you entered is correctly spelled, ensure your Mac has a stable internet connection, and confirm that your macOS version is not lower than macOS 10.15.
Step 2. Select the Volume on Your Mac Hard Drive
Select the volume where your lost data is stored, and click "Search for lost files". The EaseUS software will quickly locate all the recoverable data on the selected volume.
Step 3. Choose the Lost Data You Want
EaseUS software categorizes the scanned recoverable data by file type and storage path. Find the data you want by clicking "Type" or "Path" in the left panel. Then, check the boxes in front of the data you want to recover.
Step 4. Recover and Save Data on an External Disk
Click the "Recover" button, and a pop-up window will show up saying, "Please select a target location to save". Choose the external disk as the new storage location of your recovered data.

Step 2. Select a user; later, you'll be asked to enter a password to continue. Next, you'll be invited to the macOS Recovery mode. Choose Disk Utility on the window, and click "Continue".
Step 3. In the Disk Utility window, navigate to View > Show All Devices. (None disks are showing? Jump to #solution 2#.)
Step 4. If you're lucky and the startup disk appears here, select it, click the First Aid button, and then click Run. First Aid will check the selected volume for errors and try to repair it if issues are found.

Disk Utility can check any connected disk and repair problems once it detects them. How to repair a startup disk if it's not showing up in Disk Utility? For those who didn't see a whole disk or any containers or volumes on that disk, try to use the below steps to make it detected.
Step 1. Shut down your Mac and disconnect all peripherals that are connected to your Mac.
Step 2. If you installed macOS on an external hard drive, make sure that its connection cable is alright, and the connection is solid. Turn off the drive and back on.
Step 3. Follow the #Solution 1# guide to entering Disk Utility in macOS Recovery and repair the startup disk. If you still can't see any drive in the available devices, the most time-efficient way is to get support from Apple Support.com and start with the Mac entry.
When you try to boot your Mac from the startup disk, but it finally starts up with a flashing question mark like this, it means that your startup disk is no longer available or doesn't contain a working Mac operating system. If an issue persists each time you try to boot your Mac, you'll need to repair the startup disk with Disk Utility in macOS Recovery, which #Solution 1# has demonstrated the steps.
For the case the question mark appears only momentarily before your Mac starts up typically, perhaps resetting NVRAM (nonvolatile random-access memory) will help resolve the problem. As you know, the NVRAM can store the settings of the startup disk selection.
Step 1. Shut down your Mac, turn it on, and immediately press and hold the keys together: Option, Command, P, and R.
Step 2. When your Mac boots up, check that your preferred startup disk is selected in Startup Disk preferences.
We cannot exclude the chance that your current startup disk has failed somehow. The macOS can longer recognize it. If these options are available to you, like a CD/DVD, a network volume, or a different physical disk, you can try to change your startup disk with a working one.
Step 1. Turn off your Mac
Step 2. Press and hold the power button to start your Mac if you're using Apple silicon, and press and hold the power button until the "Loading startup options" appear.
Step 3. Click the Up arrow on Mac or the Continue button on Mac with Apple silicon to select the new startup disk when you see all the available startup disks showing up.
Step 1. Open your Mac and navigate to the Apple menu and then System Preferences. Click "Startup Disk".
Step 2. Choose the wanted disk by clicking the icon of it and clicking "Restart".
If you still can't fix the startup disk error, you can try to run a factory reset on macOS Ventura/Monterey/Big Sur or MacBook to fix the error. During the process, run EaseUS Mac data recovery software to recover data from any device.
