Will it be possible to revert to Windows 8 after installing Windows 10 (not preview)? [duplicate]

windows-8 windows-10-upgrade

Is there any reason that one could not revert to a previous OS (e.g. from a disk image) after installing the full release of Windows 10? It might be possible for MS to repartition the disk during installation, or to install a new file system that could not be read by the WinPE or Linux restore media.

Has anyone had experience, at least with the preview version, in doing a full restore? This is not exactly what is asked in Uninstall Windows 10 Tech Preview (reverting back to Windows 8.1), Uninstall Windows 10 Tech Preview... the question concerns a full disk restore.


Solution 1:

Windows 10 uses NTFS as the file system , so using WinPE or Linux restore media should not be a problem, here is a screenshot of the W10 preview edition I have installed and will not be changed for the RTM of W10.
