Ensure a fresh setup by performing a clean installation on your external hard drive.
From an external storage source... Are you referring to a USB flash drive or an external hard drive/SSD?
I haven't used it myself, but RUFUS offers the chance to pick my external hard drive as a removable unit. It seems likely to function. A brief online search suggests it should work too. https://www.diskpart.com/articles/instal...-0725.html
Yeah it's fine - But obviously be aware that anything on it will be wiped.
That's feasible. I generally recommend against it since it moves very slowly. Even a standard USB 2.0 flash drive installs Windows much more quickly than a spinning disk. While an external SSD offers convenience and speed, a USB thumb drive remains the most practical option unless you have no alternatives. The HDD performs slightly better than a DVD, but only marginally.
