    Deleted C drive, system and MBR partition. Can't make new partition


    I accidently deleted :

    - Drive C partition
    - System partition (100mb)
    - MBR partition

    when i was trying to install fresh windows 7.

    now i only have :

    - Disk 0 Unallocated Space
    - Disk 0 Partition 1: Data (Drive D)

    when i try to make new partition in Unallocated Space, it says

    "Windows cannot be installed to this disk. The selected disk is of the GPT partition style."

    Please, can anyone help me to fix this?
    And i need my Drive D untouchable. (not to be deleted)

    Try to define a primary active partition in the allocated space. Use the bootable CD of Partition Wizard - it is the last box on the website. Burn that .iso to CD and boot with the CD. Here are How To tutorials.

    Technical Support of free partition magic, partition manager servre, partition software and partition magic server - Partition Wizard

    Then you should be able to install into that partition.

    can i use bootable USB for that .iso?
    if yes, how can i make it bootable via USB?

    USB is OK. Use Rufus to get the .iso on the USB and then boot from the USB (change boot priority in BIOS).

    Back up your files, unplug all other HD's and peripherals,

    Boot into BIOS setup, reset to defaults, save changes. If an EFI BIOS you'll need to decide if you want UEFI BIOS vs. Legacy BIOS. If UEFI follow these special steps for Install, otherwise enable Legacy BIOS or Compatibility Support Module to proceed with normal install:

    Set DVD drive first to boot, HD second, set SATA controller to AHCI, Save changes and Exit.

    Then boot into Windows 7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here. I would use a fresh ISO written with tool in Step 2 as yours is in question.

    At first installer screen Press Shift + F10, or enter System Recovery Options to open a Command Box, type:

    DISKPART
    LIST DISK
    SELECT DISK 0 (after confirming Windows 7 target HD #)
    CLEAN
    CREATE PARTITION PRIMARY
    FORMAT FS=NTFS LABEL="WINDOWS 7"
    ACTIVE
    EXIT
    EXIT

    Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

    In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

    After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt. You are creating the partition here for the purpose of wiping the HD and marking Active which overcomes certain install failures.
