Hello there. I can;'t find my Lenovo IdeaCentre K410 OEM Windows 8 recovery discs. I planning on getting them before I run into a problem. I called Lenovo software support and they asked me for $199 to re-activate the warranty and send me the OEM discs. I noticed that there are many Lenovo OEM Windows 8 recovery discs on eBay for very cheap. My question is, could I use any Lenovo OEM Win8 recovery discs on my IdeaCentre K410 or I have to buy an specific one? If there is an specific one, which one is it? Where could I get them cheaper than Lenovo? Help is greatly appreciated!
