11.9 Unmounting an image
We recommend that you unmount the virtual disk after all necessary operations are finished, as
maintaining virtual disks takes considerable system resources.
To unmount an image, perform one of the following:
 In File Explorer, right-click the disk icon and click Unmount.
 Restart or shut down your computer.
11.10 Working with .vhd(x) files
Acronis backups (.tib files) of disks or partitions can be converted to virtual hard disks (.vhd(x) files).
How to use .vhd(x) files
 You can boot your computer from the converted .vhd(x) file to test whether the backup is valid
and can be recovered to a bootable operating system.
 You can keep a converted .vhd(x) file for emergency situations. For example, if your computer
cannot start and you need to run it right away, you can boot from the .vhd(x) file.
 In Windows 7, you can mount a .vhd(x) file as an additional drive. The .vhd(x) file may contain
any partitions – system or non-system.
 You can run a converted .vhd(x) file as a virtual machine.
Limitations and additional information
 A file backup cannot be converted to a .vhd(x) file.
 To boot from a converted .vhd(x) file, it must contain:
 System partition of the same computer. You cannot boot other computers using the
same .vhd(x) file.
 Windows 7 or later operating system.
 Any changes you make to a booted or mounted .vhd(x) file are saved to it. If you boot from
a .vhd(x) file and make changes to the data that was not backed up, these changes will affect
your live system.
 The standalone versions of Acronis True Image 2021 that start when booting from the bootable
media do not support conversion operations.
 Acronis True Image 2021 cannot convert .tib files that contain dynamic volumes which were
originally located on more than one disk drive (for example, spanned or striped dynamic
volumes).
11.10.1 Converting Acronis backup
Users of the Enterprise and Ultimate editions of Windows 7 and later Windows versions can convert
a .tib image of the system partition into the .vhd(x) format if they want to use the converted .vhd(x)
file for booting the operating system. Or, they may want to get the ability to mount images without
using Acronis True Image 2021.
