Can't change ThinkCentre Edge72 from to 64bit

Hi all, 

 

I've tried just about everything that's available on the net, but I can't change my windows 8 to 64 bit to use my newly installed RAM. I've tried booting from several USBs; I've tried windows' media creation tools; and I've been trying different combinations in the setup utility (boot modde to UEFI, disabling secure boot, changing the boot sequences and so on...). When running the windows media creation tool from my desktop, it tells me tha the parameters are incorrect. Has anyone an idea as to what I should do? As you can tell I'm new to all this...

 

Thanks!

Re: Can't change ThinkCentre Edge72 from to 64bit

Creating media with the existing OS creates the same 32-bit.  You need to order 64-bit recovery media (providing your system was licenced for 64-bit):

 

How can I create Recovery Media, or order from Lenovo
