System boots but keeps crashing installing Windows 10. Tried different install media and different hard drive.

The error I get is "Windows cannot install required files. Make sure all files required for installation are available, and restart the installation. Error code: 0x8007025D. It will crash anywhere from completing 2% to 97%.

battlyne, I replied with a link to an MS article, but it is being moderated which can take a few minutes to a few days.  Please search for: "Error code: 0x8007025D" and read the one from Answers.ms.com.  Thanks, John.
