cupotee....Are you telling us that you have bought a new laptop which has that dreaded W8, before asking your question in Answerbank.?
Anyway, come October 18th you will be offered a free download from Microsoft to convert W8 to W8.1 which I think is intended to make the operating system more suitable to folk who were accustomed to W7.
" failed" when it would appear to be starting up, then lots of whirring noises for ages then nothing, just the light to know the power was on and the blue light that it was connected to the internet.
