    The efi partition is formatted fat32 and the windows partition is formatted in ntfs - so no

    Ok 2 partition , but what about the third partition that is created by default when installing windows 8 ? ( And on windows 8 (MBR style ) is possible to use only 1 partition for installation)

    The third partition (not seen) is a 128MB Microsoft reserved partition..

    Yes using Legacy support (MBR) only one partition is needed..

    Boot setup via legacy support - format drive as one partition and install windows

    Click image for larger version

    So in the above image , why I need partition 1 and partition 4 ?
    Even in legacy MBR , the default installation mode of windows 8 create 2 partition the first 100Mb and Windows 8 partition , but it's possible to install without the first 100Mb partition.

    In GPT , it's possible to install only with UEFI partition and Windows 8.1 partition ?
    Thank you !

    Usually the first partition is (winre) recovery tools and it is 300-350MB

    Yours being 100MB tells me it is acting a place holder with maybe a few files..

    Open command prompt(admin)
    type> reagentc /info

    post a pic..

    You can also use diskpart to assign a drive letter to that 100MB volume so you can browse its contents

    Type> diskpart
    type> select disk 0
    type> list volume

    you will see a lot of volumes without drive letters assigned..
    Now find the 100MB volume #

    type> select volume # (# being the volume number without a drive letter)
    type> assign letter=s

    now you can browse the partition contents

    I don't understand why you wrote all these explanation ?
    My question was simple :
    In GPT , it's possible to install windows 8.1 , only with UEFI partition and Windows 8.1 partition ( so only 2 partition ) ?
    Thank you !

    Yes on 2 partitions and one MSR partition (3 Total)

    the other 2 are recovery partitions and not needed until your system fails..

    Not allowing the first recovery partition - only writes it to the windows partition anyway..

    Yes , but the question was with 2 ( EFI+System Partition ). So without the third (MSR) is not possible ?
