How can I mount an ISO via PowerShell/programmatically?

Mount an ISO from command prompt (Windows 8/2012 and above only)

If you're sitting at a command prompt and need to mount an ISO, run the following command:

PowerShell Mount-DiskImage

This will invoke a PowerShell cmdlet. You will be prompted for the path of the ISOs you wish to mount. When you are done, leave the last one blank and push Enter.

running Mount-DiskImage cmdlet

Tada! It's mounted:

Tada! It’s mounted — “Devices with Removable Storage”

Dismount an ISO

To dismount an ISO from PowerShell run Dismount-DiskImage and follow the prompt. If you know only the drive letter off the top of your head, and not the image path, use this command:

Get-Volume [Drive Letter] | Get-DiskImage | Dismount-DiskImage

This command will grab the drive you specify, find the disk image, and dismount it.

Mounting multiple ISOs and displaying drive letters

You can also use the -PassThru flag to store data passed to the command. Let’s mount a few ISOs, display their drive letters, execute a file on one of the drives, and then dismount all the ISOs.

Mount the ISOs

 $MountedISOs=Mount-DiskImage -PassThru D:\Downloads\Ubuntu.iso,D:\Downloads\Windows8.iso,D:\Downloads\Server2012.iso

Display volume info for each ISO mounted using a foreach loop

 foreach($iso in $MountedISOs){Get-Volume -DiskImage $iso}     

List J drive

 ls J:\

Open a file

 start wubi.exe

output of foreach/Get-Volume and ls

To dismount the ISOs, use the following command:

 Dismount-DiskImage $MountedISOs.ImagePath

Testing the ISO

To build a simple script that checks if the ISO is attached and is in fact an ISO (vs. a VHD) I like to use -PassThru to store the object temporarily, and use the Get-DiskImage command to update the status of the DiskImage object. This will update the Attached property. The StorageType property will tell you whether the file is an ISO or VHD according to its file extension.

using <code>-PassThru</code> and <code>Get-DiskImage</code>

The StorageType of a VHD is 2, where an ISO will return 1. Here's the output of $UbuntuISO:
Here's the output of <code>$UbuntuISO</code>

This is the output of $temp after mounting a VHD: (Mount-DiskImage can also mount VHDs!)

Note that the Attached property above is False, despite the Mount-DiskImage command running without a hitch.

Keep in mind that the $UbuntuISO variable will not stay updated either:

Technet: Mount-DiskImage

Technet: Dismount-DiskImage


Normally, if you want to do this via the command line, you need a non-interactive method. You will want to use the -ImagePath switch to do this.

Thus, the command is:

PowerShell Mount-DiskImage -ImagePath \"C:\AbsolutePathTo\Image.iso\"

Remember that if you quote the absolute path (for containing spaces and other special characters), you need to escape the quotes.

To dismount an iso image, remember to quote it:

PowerShell "Get-Volume G | Get-DiskImage | Dismount-DiskImage"

Note that we did not have to quote the command in the first case, but we do in the second, because the | pipe will cause the command line to think that it is in the command line context, rather than addition arguments to PowerShell (which PowerShell automatically concatenates into a single command).

Also make sure to spell Dismount-DiskImage correctly (no k in Dismount).
