## Backing-up your Windows installation

It is possible to back-up your Windows installation as a whole, using a disk imaging utility. Such a utility creates an exact copy of your current Windows installation, which can be saved to several discs. If you experience a major problem when migrating, having a disk image allows you to restore your Windows installation fully without losing any data or settings. However, disk imaging utilities can be expensive and also require a great deal of storage space.

Ubuntu does not currently provide disk-imaging software, and so such software can only be obtained from third party suppliers.

Below is a list of disk-imaging utilities:

- Acronis True Image*

- g4u

- Norton Ghost*

- Paragon Drive Backup*

* commercial (non-free) software
