Choose Startup Disk Mac Empty? 4 Solutions to Fix No Startup Disk on a Mac

Choosing a startup disk Mac empty would undoubtedly make your Mac machine unbootable. And if it's happening while updating a recent macOS like Sonoma or Ventura, the update won't move on without selecting a startup disk.

"Hello, I have a MacBook Retina from early 2016. I tried reinstalling the OS, but it told me there was no starting disk. How can I get one or install one? This MacBook has a soldered SSD, RAM, and no disk slot, so I'm guessing it's something I have to install. Thank you for your help." - from iFixit

Mac Startup Disk Not Showing on macOS Ventura/Monterey/Big Sur

Mac startup disk is usually an internal hard drive inside your Mac, which installs the operating system and applications. No startup disk on a Mac surely prevents you from upgrading, downgrading, or accessing your computer.

Before proceeding, ensure you have a current backup of your essential files and purchased programs (the activation key/code is quite crucial for reinstalling and activating the second time).

Solution 1. Repair Startup Disk in macOS Recovery Mode

Since your startup disk is not showing now, you cannot use the regular way to open Disk Utility by just launching the Applications folder and selecting the Utility folder. You'll enter Disk Utility from macOS Recovery mode this time.

Step 1. Depending on whether you're using a Mac with Apple silicon or an Intel processor, you'll use different keys/entries to enter this mode.

• Apple silicon: Turn on your Mac and continue to press and hold the power button until you see the startup options window. Click the gear icon labeled Options, then click Continue.
• Intel processor: Turn on your Mac, then immediately press and hold the Command (⌘) and R keys until you see an Apple logo or other image.

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.

Solution 2. Make the Startup Disk Appear in Disk Utility

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.

Solution 3. Reset NVRAM to Fix the Startup Disk Not Showing

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.

Solution 4. Change Another Startup Disk

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.

Change a Startup Disk at One Time

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. 

Change a Startup Disk for Every Startup

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".

Conclusion

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.
