    Oh crap...
    I opened that command window on the language screen as shown in the tutorial, typed all the commands including the "clean all" but I awaited almost an hour but dint get the message that it suceeded in cleaning. I have 250 GB HDD.How long should it take?

    I didnt await longer and dint type that command "convent GPT" ( btw are u sure its not CONVERT instead of Convent ? ) closed the command window and I continued with install. It seems it cleaned something since my drive shown as a single unallocate space. Cliked New > Aply>Ok (as it says in that "clean Uefi instal tutorial") but instead of those 4 partitions that suppose to appear I got only the System one and the Primary one. I might retry later but dont know how long to further await for that "cleaning".And pls confirm if its convent or convert gpt. Also in the case it works and finally shows that succeed in cleaning I need to type right away the new comnand Convent gpt right? and what happens after I type this? Need to wait a bit? and then close the windows from the x button and continue with win8 install or type exit twice to leave the dikpart and window ? or something else?

    oh so its CONVERT not Convent .Obvious !! but I see you continues with misspeling it so after suceeding in coverting it should I type exit twice or to simply close the window with the x button and continue with install?

    exit twice or X, both do the same.

    Ok I think ive done it well this time.cleaned it, converted it and then Ive got those 4 partitions from the unallocated space : recovery, efi system, MSR an the primary where I could instal windows without the warning. Now my disk management looks like this. Its ok right? even I dont see that MSR one

    Looking looking good.

    MSR is hidden in disk management.

    You have got into a same problem which i faced yesterday.

    Here is what i did.

    1) Insert Windows DVD. You may use USB.
    2)Select Language.
    3)In Install now page, Press Ctrl+F10. (elevated command prompt opens)

    4)Type : diskpart (diskpart loads)
    5)Type : list disk (You will get the list of HDD/SSD present in your system, with number to identify each)
    6)Type : select disk <disk number>
    7)Type : clean
    8)Type : exit (twice, first to exit diskpart , then to exit elevated command prompt)

    9)Select Install Now.

    10) Select Unallocated space and click next.(Windows automatically creates 3 necessary partitions)
    If you want to create partitions, Create it by Selecting Drive options, Clicking New and entering the size in MB.
    Finally Select the Partition for your windows and Click Next.

    11) Thats it! You have completed your Windows installation.

    If I am not Clear to you. Go here.
