    Can you open Disk Utility, select your hard drive,then look in the bottom right corner, and see if it shows GUID.

    Next select the OS partition and on the lower left does it show Mac OS Extended (Journaled)?

    Did you ever get a backup made?

    I had the same problem... Mismatch between MBR and GPT would not allow Yosemite to be installed. Finally did a Repair Permissions in the disk utility and that cleared up the problem and I was able to install Yosemite.
