I have purchased a lot of Microsoft programs during last 15 years so I think I deserve a better support but I was disappointed. I will not buy Windows 8.1.
You don't have to. I don't think MS is forcing to buy 8.1, you bought an original MS license as I did and I paid just $14.99 with the promo code.
I'm not sure about SSD disks, but I think that all failed installations are all within a software environment, despite of MS confirming that 8.1 is not supported by some older AMD processors and some other Sony notebooks...
At first, I was reluctant to refresh my W8 system because I read elsewhere that others were unable to update to 8.1 even refreshing their systems. But again, their fails were due to inactive boot partitions and so.
Keep trying pal, in my case I was also about to throw in the towel with 8.1, but now that I got it I'll never look back to any previous OS.
