First of all, I'm sorry for duplicating but I don't want any issues.
Hi, I want to install Windows 10 without any dual boot on my laptop (HP 250 G5), beacuse I want to update my BIOS, and the only way to update it is to run an exe.
How can I backup everything, from softwares installed, packages, repositories to settings, wallpapers, etc; and restore it, after reinstalling Ubuntu 16.04.
I have an 1TB external HDD if that helps.
