I got a new Lenovo Z580. It came with Windows 8 Basic but I really don't care much for it. Dual-booting seems to be a good solution since I like Windows 7 and maybe Windows 8 will grow on me. I've already wiped the HDD, installed Windows 7 Ultimate 64bit and Windows 8 Enterprise 64bit. The system is UEFI with GPT. Everything went fine with the install and I used Cody's Microsoft Toolkit to activate Windows 8. I did not realize it would not work with Windows 7 Ultimate. I was going to use Daz's Windows Loader for Windows 7 but the readme file says it will not work with UEFI. What should I do at this point? I read a thread (h**p://forums.mydigitallife.net/threads/18888-Question-About-Ultimate-and-Enterprise) that said it's possible to rename the EditionID to Enterprise and "upgrade" to Enterprise using an Enterprise disk and then use the Microsoft Toolkit to activate. Is this a reliable way to overcome my activation issue or should I do something else?
