I'm trying to install Windows 10 preview on Mac OS X with Parallels, but the ISO file is not recognized by Parallels. The ISO is not defect, I've checked the Hash.
I had a similar problem installing the WindowsPreview in Parallels 9.
- Clone an existing Windows 8.1 VM
- The bit-levels of the VM and the downloaded
WindowsTechnicalPreview.isohave to be the same (64-bit>64-bit or 32-bit>32-bit respectively ).
- Mount the
WindowsTechnicalPreview.isoin the VM and install with
setup.exe. You will be asked if you want to keep your private files or wipe all.
Windows 8 and 7 should work as well.
