    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?

    mod bios with slic 2.1
    identify model properly by type under it. many board models for lenovo usually... get right one

    or likely needs SLP marker tool for slic 2.1 to be unlocked

    Thank you both. I downloaded the files but I still do not know what to do even after reading the included manual.txt.

    Presumably, you think I should unlock slic 2.1 (although I don't know how) then use an OEM key for Windows 7? Windows 8 is OK because I already used MS Toolkit?

    The key to this setup is to enable Legacy Support as Windows 7 is not able to boot from pure UEFI
