    I want to Format my C-Drive in order to reinstall Windows 10 OS

    But when the step comes ''which drive you want to install'' i format the C-Drive and suddenly it says i windows cannot install in that partition, if you know what i mean

    I mean i delete the C-Drive then make C-Drive partition again ( i have other 2 partitions without C-Drive and they have Important Data which are not saved+ i don't want to delete those partitions for installing Windows) and it don't take that partition to install Windows, so then i had no other way but formatting Whole Harddisk and make partition again

    All my non-backuped data gone

    How to get rid of it ?

    How can i perform installing Windows without losing my data or breaking other partitions ?

    i have a bootable USB with FAT32 format

    and in BIOS, 2 options came UEFI(USB) or Normal USB, what do i choose

    Please someone help

    :)

    Change partition as system and to drive C

    As far as I'm aware Windows is mostly used as the C drive, therefore it is unable to delete itself so to speak, I'd recommend using your Windows installation disc and reinstalling the OS of your choice onto the known C drive. and whilst using the Windows disc delete/format the other drives/partitions to what you want/need.

    EDIT: just read your Win7 disc is screwed... how about cloning your Win7 installtion to the current C drive? However I don't think this will be as effective in the long term due to your drive setup and also will no doubt leave the Vista files.

    W7 Hard drive partition issue

    to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

    - press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
    - diskpart <-- start the windows command line partition management tool
    - list disk <--- list the installed hdds in this computer for the next step
    - select disk 0 <- might have to replace 0 with the number of the correct disk
    - clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
    - create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
    - exit, exit to exit diskpart and the command prompt
    - click refresh in partition manager and select your newly created partition and install to that
