4 ways provided in this article to mount or unmount Windows image backup VHD or VHDX file in Windows 10/8/7 and Servers, just refer to the step-by-step guide to mount VHD/VHDX. Please read on.
VHD, short of Virtual Hard Disk, is a file format that represents a virtual hard disk drive. If you create Windows image backup using Backup and Restore, you now get Windows backup to VHD and you will get a WindowsImageBackup folder in the destination, and the path is just like:\WindowsImageBackup\computer name\Backup YYYY-MM-DD HHMMSS. There can be multiple. VHD files and several .xml files. How many VHD files mean that you have how many disks or partitions.
VHDX (Virtual Hard Disk V2) is the successor format to VHD. Now disk images use VHDX format instead of VHD because of the difference between VHD and VHDX: capacity limit. VHD is limited up to 2 TB while the VHDX is limited up to 64 TB. You can mount VHDX just like mounting VHD.
Sometimes, you have to mount the VHD or VHDX file to access files from the backup, what should you do? There are 4 ways included in this article for you.
Here is the guide to mount and unmount VHD or VHDX file with Disk Management:
Mount Windows image backup with Windows Disk Management listed below.
1. Right click This PC -> Manage, select Disk Management, or you can open the Disk Management by pressing Win+X (Win10), select Disk Management.
2. Click Action, select Attach VHD.
3. Then, locate the Windows system image VHD/VHDX file by clicking Browse and hitting OK.
4. After the file is attached, you will find the partitions or disk did not show in File Explorer but only visible in Disk Management. Now, what you should do is assign drive letter for the partitions on the mounted disk: Right click the partition > Change Drive Letter and Path... > Add... > Choose a drive letter > OK.
Now, you could browse files, copy files, drag and drop files, recover single or multiple files from your Windows image backup.
1. In Computer Management, click Action > All Tasks > Detach VHD.
2. And then click OK.
Or you could right click the mounted disk, and select Detach VHD. It will execute the detachment immediately.
Note: Detaching VHD or VHDX is a little different in Windows 7. Please do not check the box of “Delete the virtual hard disk file after removing the disk”, or your system image backup will be deleted.
Besides, you could use the Mount-VHD command to mount one or more Windows image backup VHD or VHDX files in Hyper-V, Windows Server 2012, 2016, 2019, 2022.
The syntax of Mount-VHD is listed here:
Mount-VHD [-Path] [-NoDriveLetter] [-ReadOnly] [-SnapshotId ] [-Passthru] [-CimSession ] [-ComputerName ] [-Credential ] [-WhatIf] [-Confirm] [(CommonParameters)]
For example, mount the VHDX file located in \\192.168.0.230\sharefolder\WindowsImageBackup\DESKTOP-EL3UFCG\Backup 2020-12-15 075201\10ae79f1-3117-4168-b159-19790f1113bf.vhdx, please input the command:
Mount-VHD -path \\192.168.0.230\sharefolder\WindowsImageBackup\DESKTOP-EL3UFCG\Backup 2020-12-15 075201\10ae79f1-3117-4168-b159-19790f1113bf.vhdx
Here is the detach VHD or VHDX command:
Dismount-VHD –Path "[location of vhd]"
For example:
Dismount-VHD \\192.168.0.230\sharefolder\WindowsImageBackup\DESKTOP-EL3UFCG\Backup 2020-12-15 075201\10ae79f1-3117-4168-b159-19790f1113bf.vhdx
Sometimes, you will get the error: The term 'Mount-VHD' is not recognized as the name of a cmdlet, function, script file, or operable program. To fix it, you have to install Hyper-V first.
Run the following commands from an elevated command:
diskpart
select vdisk file="D:\WindowsImageBackup\DESKTOP-EL3UFCG\Backup 2020-12-15 075201\10ae79f1-3117-4168-b159-19790f1113bf.vhdx"
attach vdisk
And you could unmount the VHD or VHDX file with the command:
diskpart
select vdisk file="D:\WindowsImageBackup\DESKTOP-EL3UFCG\Backup 2020-12-15 075201\10ae79f1-3117-4168-b159-19790f1113bf.vhdx"
detach vdisk
However, you might encounter the mount VHD error like: Sorry, there was a problem mounting the file. Or you don’t have permission to mount the file. The fix is to copy the VHD or VHDX file from one location to another, and mount it.
If you still have problems mounting the VHD or VHDX file, please try the next solution.
