When I install mac os high sierra or Mojave on my VirtualBox virtual machine. I meet an error that is can not select target disk to install the mac os. After investigate I finally find a method to fix this issue. This article will tell you how to fix it step by step. The issue may happen when you reinstall macOS on MacBook also, you can also follow the below steps to fix it.
1. How To Reproduce Can Not Select Disk To Install MacOS Error Window.
- Start the virtual machine, then select the second item Reinstall macOS in macOS Utilities window, click Continue button.
- Then it will popup install mac os high sierra or Mojave welcome window.
- Click the Continue button in the above window, then click Agree button in the next window. And then it will go to another window to let you select the disk where you want to install os x. But you can not select the disk because there is no disk to select.
2. How To Fix No Disk To Select Error When Install Mac OS On Virtual Machine.
The reason for this issue is because there does not has a partition on the virtual disk, so we should first create a partition on the virtual disk, then you can select the virtual disk partition to install mac os.
- Click Install macOS High Sierra —> Quit Install macOS menu item at the virtual machine window top-left corner to quit mac os installation wizard.
- Then select Disk Utility in macOS Utilities window, click the Continue button.
- Select the virtual disk in Disk Utility left panel, then click Erase button at the top bar, it will popup a window. Input the partition name, select partition format Mac OS Extended ( Journaled ) in the format drop-down list, click Erase button at bottom of the pop-up window to start creating the partition.
- When the creating partition process complete, click the Done button to finish it. Then close the Disk Utility window to go back to macOS Utilities window. Now you can select Reinstall macOS to install it again, and you can select the virtual disk partition during the installation process now.
3. Tips When No Disk To Select Issue Happen On Physical MacBook.
If you find this issue when you reinstall macOS on a Physical MacBook, the above method also makes sense. But one thing you should take care of is the physical HDD cable, you should make sure the HDD cable is plugged in tightly.
4. How To Fix Get Stuck With Gray Screen Issue At The Beginning Of macOS Mojave Installation Process.

Awesome! Thank you for much for the helpful article. It worked for me.
Thank you so much! I was tearing my hair out trying to find this solution. Fixed it straight away for me.
Happy to hear this article helps you to fix your issue.
Gave it a try for myself as I was not able to find a disk to install MacOS High Sierra
I went to disk utility and found no drives that were named VBOX Hardware Media or something close to that, nor did I find any drives at 100gb (even though I have already have a drive with 100gb available.
Tried adding a second 100gb drive, but that didn’t work either
You can click the View drop-down list at the left top corner of the disk utility window, and select the Show All Devices, or Show Only Volumes menu item to display all the VBOX HardDisk.
thank you so much it worked
Thank you so much
This helped a lot for me
This step was labeled differently (I copy and pasted the step I’m referring to below). There was nothing labeled “virtual disk” or anything like “VBOX”. I also didn’t get a pop-up window, but there was a place to put in the partition name “Main Disk” kind of like the example. And it had a default partition default of “Mac OS Extended (Journaled)” and a place to click erase. Voila! The rest of the steps unfolded as presented in this AWESOME tutorial. Thanks, thanks, thanks!

Thank you so much ! This actually worked and I had no CLUE of what the heck I was doing . Thank you lifesaver .
Thank you. I can get past the no disk to select issue.
There is a small step missing that’s tripping up some.
You have to click VBOX HARDDISK Media on the left, then Erase.
Worked like a charm for VMWare giving me that same issue. Thanks heaps!
Worked for me. macOS Catalina on VMware gave me that problem.
Can confirm this worked for me too on VMware
Thank you for trying to help, but this did not work for me. I have the same problem as above, but I cannot click the “Erase” button in Disk Utility. It is light grey. I am able to click the First Aid button and it says that the repair is successful. There is still no disk to install when I am asked to select the disk I want to install OS X.
Did you figure out a fix? I’m having the same issue
Any luck? I am in the same boat now.
Did u figure it out? Im having same problem
You can click show all devices in the apple disk utility, in the top left corner. Then all the disks will show up and you can format the one you like.
Maybe you need to mount the disk by hand. You can right-click the Virtual Disk in Disk Utility window left panel and then click Mount button in right panel top area to mount it, then erase it.
