I'm using dell inspiron 3542 preinstalled windows 8.1
I want to upgrade to win 10 by availing free offer but I want to create a recovery media of existing OS win 8.1 to use incase of something failure
NOW
I have two options to create recovery derive or media
1: Dell Backup and Recovery program provided by dell which is preinstalled!
2: Create Recovery derive tool which is available in windows 8.1
Suggest me which is the best option and how its better from other?
also which media should I use USB or DVDs?
please as well mention method to use/test recovery media after creation of recovery media whether its okay or not?
THANKS
