I have a Lenovo X1 Carbon Gen4. After days of trying to get Win7 to install, I have W7 Ultimate but am using a GPT partition table. Since it is Ultimate, I can't use kmspico Since it is GPT, I can't use loader. Which option would you recommend? Try to convert GPT to MBR? (I had alot of trouble getting the bios to detect the OS? Convert Ultimate to Ultimate Enterprise? Some other tool?
