Whats the deal when I installed V.9.3633 it messed up my MBR? So I got a non-system disk error? It happened on 2 pcs. I restored an image I had made w/ TI 8.0 -- but it did not fix the MBR. I had to download the ISO image to fix it. Now I will not reinstall 9.0 b/c it seems it will mess up the MBR again. This is NOT NORMAL. As a matter of fact I want a refund.
