The following is the complete procedure. If you really know what you are doing, you will realise you can miss out some of the steps.
- Disconnect the machine from the network.
- Install Windows10 from the media. Select 'I don't have a product key'. Select 'Custom: Install Windows Only'. This will create all the partitions (C: EFI Recovery) and give you a Windows 10 machine to work on.
- Login in.
- Create the folder C:\MountedVHDX
- Create the folder C:\WindowsImage and copy the folder matching your machine from your backups WindowsImage folder.
- Attach an external disk with at least as much free space as your SIB. *I assume that the external disk is E:*
- Create the folder E:\CapturedWIM
- Launch powershell and execute...
Mount-WindowsImage -ImagePath fullpathofvhdxindoublequotes -Path c:\MountedVHDX -Index 1
New-WindowsImage -CapturePath C:\MountedVHDX -Name Win10Backup -ImagePath E:\CapturedWIM\sib.wim -Description "Windows 10 Backup" -Verify
Dismount-WindowsImage -Path C:\MountedVHDX -Discard
- Restart Windows.
- At the login screen click on the power icon and click restart while holding the shift key. The machine will restart in recovery mode.
- Select Troubleshoot->Advanced->Command Prompt
- When the command window appears execute...
Format c:
*Dism /Apply-Image /ImageFile:E:\CapturedWIM\sib.wim /Index:1 /ApplyDir:C:*
- That's it. When you restart, your windows will still be activated.
