On another note, never lose your only windows USB installer.
You'll find it's impossible to install windows again. You can download the ISO, but it doesn't come with the drivers. Conveniently, the drivers on the OEM website are all in .exe files, which you can't easily run on Linux and therefore you cannot extract them.
TL;DR make a backup windows installer with rufus and hide it somewhere or you're SOL.
