    Right so,

    I have done all sorts of **** to this SSD because i got OCD formatted it changed its drive letters and all kinds of other stuff still wont work. I have my other HDD running at the moment it has windows 7 on it but i want to install a fresh windows 7 on my SSD but it wont let me it says " setup was unable to use the existing system partition because it does not contain the required space".

    Am i doing something wrong or does the SSD need to sent back ?. Cheers!.

    When you enter windows setup and you are sitting at the partition screen

    press shift + f10 on your keyboard

    this will bring up the command prompt

    type:

    diskpart then press enter

    type list disk then press enter

    see what the samsung SSD disk number is, then note it

    now type: select disk X (where X is the number of the samsung SSD disk)

    now type: clean then hit enter

    now type: convert gpt or convert mbr depending which disk format you want

    now exit

    on the Windows partition screen, press the REFRESH arrow

    now when you see your unpartitioned space on the samsung SSD, click create and choose the size (with a 256 GB disk, I would only setup one partition not more, offcourse, other than those little system partitions that Windows setup creates which is fine)

    let me know how it goes, I am OCD like you and nothing beats a clean install to get max performance, make sure you are in AHCI mode in the BIOS

    If you are installing Windows 7, make sure you disabled the following in BIOS:

    Windows 8 Fast Boot
    Secure Boot

    then make sure you have legacy boot tom enabled or on some systems, it is called, Enable CMS

    Should be type: list disk

    And you don't even have to go through all that. Just when installing when going to choose partition, choose advanced, and then delete all partitions and then select the open space.

    Choose Custom (Advanced)

    Click on "Drive Options Advanced" at the bottom

    Then it will give you partition editing options at the bottom. Delete all partitions then click "Next".
    THIS WILL DELETE ALL DATA ON THE DRIVE!
