I really need to:

a) Shrink my Windows SSD partition using an outside program of some sort -- maybe GParted bootable? Need to double-check)

b) Set up a generic EXFAT SSD partition for shared storage.

c) Probably set up similar for some other drives.

d) Fix my Ubuntu install or maybe try another Linux distro.

e) Finally get that Windows 7 secondary install working right so I can mod older Bethesda games/Fallout:NV, as Windows 10 disabled the workarounds for the 32-Bit Video RAM limit.
