My friend wanted me t install Windows 8 his laptop and I'm pretty sure it came with Win 8 64 Bit Core but product key in the bios or where ever it's stored won't activate it. I used a Win 8 AIO DVD I had,what's the problem do I need to download Win 8 OEM ISO an use that,I installed Core 64 Bit not the N or E version or whatever it has after it. I found the product key using Magic Jelly Bean Key Finder is there anyway to check to see what version it's for. Also this was a key supplied by dell and the model of the laptop is not on the laptop if you need that to help more I need someone to tell me of a program I can use to find that out.
