I upgraded my Lenovo Ideapad Z 570
to Windows 8 a couple of days back. But the new OS is a pain. it has slowed down my system substantially and also some reference memory......terminated
kind of errors are also displayed frequently. may b this is coz i did not do any BIOS upgrade before switching to Win 8. Was i supposed to? Tried calling the customer support and they asked me to contact microsoft about the problem.
Whatever..what i want now is to go back to my previous win 7 and would appreciate if you people would guide me. i saw a discussion on the same topic in the forum for an acer pc, so would be glad if you help me out as well.
I have never run any backup or anything. data is not much important anyway.just some movies etc.
i have the win key on my laptop, but there's no cd.
PS: Located in India..if that makes any difference to the kind of updates available.
