Oh I know it can be installed, but after the headache I got re-installing 10 once before and then trying to get 11 running on…anything, really, i just decided “you know what? What will be will be at this point. I’m not gonna need it for much anyways.” when i finally got 11 to accept and install into a random external drive that i never really used (it didn’t like the one i had inside my PC reserved specifically for it. Somehow…).
(Note: this was a while back, so installation could be a helluva lot better now and i have upgraded a bit since then but, shrug. Already got Windows ready to go on a drive, and only have it because I might need it moreso than me actually wanting to have it, so meh)
