It then has me redownload and reprepare...

Why isn't it installing?

Few reports of issues like this but no common fix yet as everyone is reporting different things, might be easier to reset the MBR.

Either way, in the future make sure you run a regular backup. Recommend a snapshot tool (i.e. RollBack Rx) or a disk imager (i.e. Macrium Reflect).
