    Why? Windows can NOT be installed on a FAT filesystem. It should be NTFS. But then again, Windows does NOT need you to format the file system beforehand (it would be a pretty lousy installer if it couldn't create the file system it wants to install the OS).

    Once again, the way you partitioned and formatted the USB is irrelevant to how you need to partition and format the target disk. It's not because the USB was using GPT and FAT that your target drive has to use GPT and FAT, or that you actually need to format your target drive at all.

    I'm pretty sure that what the installer was really complaining about, if the only available partition on your target drive was using a FAT filesystem, was that there was no partition it could use to install Windows.

    If both your USB and the target HDD were indeed using the GPT partition scheme, and you had formatted the partition you wanted to use for Windows installation on the target HDD with a FAT file system, the installer will definitely complain about that.

    Next time I will leave the target HDD alone and let the Windows 10 installer sort the drive out.
    Good thinking. Only the OS installer knows what it really needs to install the OS, and is usually smart enough to create it. Trying to second guess, and create things beforehand is usually a recipe for issues.

    hello, i got problem n still unresolve..

    trying to install win 7 64 bit for my sony vaio E series.. but got stack and cant do anything.

    when im using legacy mode, it can go through booting to enter instalation proccess but got error on partitioning menu, it says "windows cannot be installed on this disk, this computer hardware blablablabla. ensure that the disk blablabla".

    so i think i should use uefi mode, but no progress at all,it stuck at logo screen booting no matter how many times i've tried.

    then i tried using bootable usb efi (in this thread tutorial). again, it got stuck with error at booting "\EFI\Microsoft\BOOT\BCD. Status 0xc0000000d" no matter how many times i've tried, either using rufus or manually.

    my goal is to be able to install win 7 64 bit.

    btw SV's bios is somewhat simple, it's just provide boot mode and priority change, no advance boot for like CSM n stuff i've been reading.

    pls help..

    Hi guys,

    I may be missing something and I have to admit I didn't read all the 52 pages of subnotes and the rest of the forum. So if this was solved before, I apologize and would be satisfied with just a link to that thread.

    Any ways this is my problem.

    I'm trying to create a UEFI USB flash drive to install Win 7 Pro x64 with SP1. I tried twice using Rukus and then becouse it didn't work once with "Diskpart", both times using instructions on this forum.

    When I select it from the boot options it hangs on the black screen, before the Win logo starts to esemble or what ever MS called that.

    My current configuration is: Win 10 Ent, installed with GPT and UEFI, secure and fast boot disabled.
    I have cretated a vsdx. on dirve D:\
    My only goal is to get the working Win 7 Pro intallation and then officaly upgrade it to Win 10 before 29.7.

    Tnx for any inside.

    Regards,
    SteelCat

    Hello SteelCat, and welcome to Eight Forums.

    Where did you get the Windows 7 ISO from? If not from an official source (ex: Microsoft), then that could be the issue.

    Hello Brink,

    tnx for a quick reply. The image is from an officiall source, but it was modifed so it doesn't ask you for a key, in the first part of setup. Insted it displays a list of Windows images on the drive (similar that it was with Win Vista, if you choose to imput your key later).

    But I installed with that image before in non UEFI mode and It was fine.

    I have an RTM version also somewhere, I will try with that later.

    Regards,
    SteelCat

    P.S.: One more question does the actvation of a free genuine windows 10 differentiate between boot modes when it makes your harware fingerprint. As I said my goal is to get a working win10 licence so I might be able to use it later. It would be a shame to vaste a working win7 key.

    It's possible that whatever you did to modify it will cause it not to work with UEFI, and only Legacy BIOS.

    Activation isn't affected by installing in UEFI or Legacy BIOS.

    I was attempting to install Windows 7 x64 on a GPT disk and was getting the "Windows cannot be installed to this disk. The selected disk is of the GPT partition style." error because my USB would not boot in UEFI mode.

    Step 11 was a lifesaver, it was exactly what I needed to make it work. Thank you so much for this tutorial!
