I think the hdd is 1/2 dead in this thing. It seems to load pretty quickly, but the disk usage is always high (Win8 is on it). Once it loads

I see there's a system settings program in windows, that lets you change whatever.

But it does bugger all. I can change it so it boots from USB. But if I plug a USB flash drive in, to try and boot from it, it does nothing

I've tried ESC, F1, F2, after it restarts, does nothing. I've disabled fast boot in this system settings program, it still boots into windows
