I want to do a backup of Ubuntu to install windows 8.1 and then later on dual boot it with Ubuntu, without losing my data.
I'm currently using Ubuntu 15.10 operating system, and I sincerely love it, but I need windows 8.1 in order to play some games. So, my first idea was backing up all of my data in a external hard drive of 1TB, install windows 8.1 and then install Ubuntu again but without losing any of my data. I've tried to backup everything in hard drive before, and i did, but, later then when i reinstalled Ubuntu i didn't know how to restore my files!
Is that possible? If so, i would be really happy if someone could help me with this.
Also, I accept any suggestions that not backing up in an external hardrive.
