How to Transfer Data and OS (win 10) to new WD drive

the situation: Win 10 version 1803 update completely bricked my PC. Boot USB stick did not work completely. Tried everything. Hard drive in PC was Seagate 1TB over 6 years old. Had backed up drive to external 1TB using seagate backup tools. Now what ? How to get data from Backup external drive to New WD drive. (sorry I am only half literate in the backup knowledge and could not find Youtube video that could help. Thanks to all

You can just directly drag n drop data files from Seagate backup drive to WD drive.
