    Hi I am trying to install Windows 7 on a cheap windows 8.1 laptop with an EMMC SSD instead of an SSD. Windows 7 doesn't' natively support EMMC, I want to slipstream drivers into my Windows 7 Installation so I can install it on my laptop.

    Q) Where can I get EMMC Drivers for Windows 7 ?

    Thanks!

    This is awesome, I've been having the same problem too. There are many new laptops these days with emmc and people might want win 7. I made a thread here as well but we couldn't find the drivers.
    @WindowsBrownie, how did it go?:biggrin: If you had any success I would love to know how you did it.

    Thankyou windsman. In device manager, the emmc Hd (samsung mbg4gc) is under the class 'disk drive' and has hardware id of 'SD/GenDisk'. But doubledriver also shows another device with hardware id 'SD/CLASS_MMC' with the title 'SD storage class controller'. Also doubledriver lists the hardware id of the hd as 'GenDisk' as opposed to 'SD/GenDisk'. Here is the driverlist. Second question: will this generic driver only work with 64bit win 7?

    Thanks, well, as i never tested Emmc driver, i don't know if it could work, but maybe.

    I think you could integrate the two backuped drivers related to the disk, to Seven ISO, and test if it's work, but again i really don't know.

    Don't forget to backup all imporant files before testing because if is it's not working you have to revertback to Windows 8.1, fresh install, be sure you've got a 8.1 iso image, anyway Windows 8 iso's are avaible on MDL.

    These drivers seems to be x64 compatible.

    When I boot win 7 (without extra drivers) and do 'list disk' command, it says 'there are no fixed disks to show'. Should I integrate chipset drivers too or will the emmc be enough?

    First of all chipset are not drivers, these are just *.inf files, you don't need to integrate them.

    Ok I integrated those 2 drivers (to install.wim) using that toolkit. Created a uefi iso (x64) using the same tool, and used rufus to burn to usb (GPT)

    Result 1: boot option = UEFI. I got frozen at the 'windows starting' screen with the 4 colored dots. Strange, without the integrated drivers it doesn't freeze. What's happening here?

    Result 2: boot option = legacy. It doesn't freeze but I get the same 'load driver' error and 'no fixed disks to show' I'm assuming the integrated drivers weren't even loaded under legacy. So this result is probably irrelevant.
