通过 Powershell 使用驱动器号挂载 ISO

Question

I am trying to mount an ISO and I would like to associate a drive letter with that mount. I would like to specify the drive letter as say Y:\ The below does not work, can anyone help me out. Thanks

#Variable Declaration
$isoImg = "P:\Software\Windows10CurrentVersion\Windows10.iso"

#Mount ISO and Gather Drive Letter
Mount-DiskImage -ImagePath $isoImg -PassThru | Out-Null

#Obtain Drive Letter
$driveletter = (Get-DiskImage $isoImg | Get-Volume).DriveLetter

Answer 1

You could mount the ISO and accept (for now) the automatically assigned drive letter. It is possible to change that afterwards, but you will need to run that as Administrator:

# the full path to the ISO file
$isoPath = "P:\Software\Windows10CurrentVersion\Windows10.iso"

# mount the ISO, but first check if it is already mounted
$isoDrive = Get-DiskImage -ImagePath $isoPath
if (!$isoDrive) {
    $isoDrive = Mount-DiskImage -ImagePath $isoPath -PassThru
}
# $isoDrive is a Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_DiskImage

# get the DriveLetter currently assigned to the drive (a single [char])
$isoLetter = ($isoDrive | Get-Volume).DriveLetter

Rename the driveletter for this drive.
This part needs to be run as Administrator

# find the volume by its automatically assigned driveletter and set the new drive letter
$drive = Get-WmiObject Win32_Volume -Filter ('DriveLetter = "{0}:"' -f $isoLetter)
$drive.DriveLetter = 'Y:'
$null = $drive.Put()

To dismount the iso drive:

$isoDrive | Dismount-DiskImage | Out-Null

Hope that helps

You can mount the ISO image and then assign the drive letter like this:

# ISO image - replace with path to ISO to be mounted
$isoImg = "P:\Software\Windows10CurrentVersion\Windows10.iso"

# Drive letter - use the required drive letter instead of Y:
$driveLetter = "Y:"

# Mount the ISO, without having a drive letter auto-assigned
$diskImg = Mount-DiskImage -ImagePath $isoImg -NoDriveLetter

# Get mounted ISO volume
$volInfo = $diskImg | Get-Disk | Get-Partition | Get-Volume

# Mount volume with specified drive letter (requires Administrator access)
mountvol $driveLetter $volInfo.UniqueId
