I decided to upgrade an Acer Aspire X1440 (Win 7 64bit) to Win 10, it just wouldn't work. Kept failing at 32%, which seems a common enough problem, tried all the fixes which didn't work so tried to install from USB. This also failed.

I was pretty convinced that it was a graphics driver that was the issue so I thought I'd format the HDD and try again. Win 10 still won't install, in fact nor will Mint, or Ubuntu (ACPI PCC Probe Failed), and of course I've lost the Win 7 recovery partition.

It was only after I did all this that I found that according to Acer you cannot upgrade this device to Win 10.

I now have a nice, hardly used Acer Aspire X1440 with 1TB HDD and 8gb RAM that doesn't boot into anything. Seems a shame to bin it but I can't think of anything else to try...
