Windows 10 Install Error code 0x8007025D

After getting this error attempting to install from USB stick and from a DVD created with Windows Media Creation Tool on an old system with a 160Gb Hard Drive the solution was to delete all existing system partitions on the Disk drive leaving a large unallocated block to assign for the new windows installation.

Full Error Description:

Windows cannot install required files. Make sure that all files required for installation are available and restart the installation.

On a later occasion the same problem was resolved by creating a new USB Installation drive using the latest Windows 10 version, 21H2 at the time.

On another occasion the same problem was resolved by using a DVD installation disc rather than a USB stick.
