@Parabolaralus Yeah I'll either figure it out or install linux (what is a good distro for dell laptops?). This pc I found at a garbage dump, the hard drive was failing, the battery shot, and it was a little beaten up from being discarded. I restored it with a ssd, and a new battery. I think it came with windows 7, but there was no sticker on the back. I downloaded the USB Windows 10 upgrade from microsoft, these were free upgrades some time ago. I had assumed Education postulating that it would activate for free, but I have no qualifications for those terms. Back on topic: ExFat has been working great with allocation unit size 8192b. NTFS-3g may have been a problem in particular with dosbox because of the write syncs.
