Can't boot windows 7 64 bits

[Krazus]

Hi.

So i bought this laptop 2 years ago:

http://www.samsung.com/us/support/owners/product/NP355E5C-A01US-search

And as u can see on the link it came with windows 8 64 bits, but i boot it to windows 7 34 bits. Now i want to play a game with my girlfriend but this game requires a 64 bit version of windows, so i tried to boot my laptop again but now with windows 7 64 bits and i couldnt finish the instalation because an hardware problem. So can my hardware support windows 8 64 bits but not windows 7 64 bits? Would it work if i boot it with windows 8 64 bits? Or should i give up all this idea and back to 32 bits?

THX in advance

Just use Windows 8 64bit, it is better for your machine in every single way, as the drivers are certified for Window 8 and the machine is known to work properly with it. The machine will require a full format to install the 64bit version, so back up data.
