I recently started using Parallels 10 with a trial version of Windows 8 on my MacBook Pro. Given my trial version is going to be expiring soon, I purchased windows 10 from the windows store online. I downloaded it (no physical product) and had a valid windows key. The installation was going fine until I got this error. We couldn't install Windows 10 0x8007025D - 0x2000C The installation failed in the SAFE_OS phase with an error during APPLY_IMAGE operation. Anyone have any ideas on how to fix this?
As per the error suggests, you cannot upgrade from a preview version of Windows to Windows 10. Rather, try to install a new virtual machine of Windows 10 by downloading the ISO from http://bit.ly/1LT6FpT and installing Windows 10 as per the steps given in the article http://kb.parallels.com/4729
