    Windows 7 USB installation- setup was unable to create a new partition


    Hi guys,
    I am using windows 7 ultimate 64-bit edition.When i tried to dual boot my system with Ubuntu, I accidentally formatted the hard-disk and when tried to re-install my windows 7 OS through USB drive I receive an error stating that windows cannot create a new partition or locate an existing partition. Please refer to log files. My CD drive is not working and I tried to manually part the hard-disk using Gparted and Diskpart but still it was of no use. Is there any solution for this problem?

    Additional Information:
    1.I have two hard disk installed on my system- both are seagate 1Tb sata disk
    2.I have the windows 7 ulitmate iso file with me
    3. I tried creating a bootable usb using unviersal usb installer and the windows usb download tool

    I tried the load drivers option but the error given there is that there are no signed drivers. Tried manually downloading intel sata ahpi drivers but still no use

    1) Clean the HD Drive, using Step one in this tutorial:

    Still i receive the error setup was unable to create a new partition or find an existing partition. I tried manually creating the UEFI bootable USB flash drive manually and using Rufus. If I try to do it manually the usb is booting up but i receive the error. I tried using rufus but the usb wont boot it is just stuck on the black screen which comes before the boot.
    BIOS seems to be working properly

    Edit:
    Also tried cleaning the HDD as mentioned before

    I read a solution online that stated that I should connect my hard disk as an external drive and then install the operating system. Is it possible to install the OS on an external drive

    Try replacing the USB Pen drive.

    Did you unplug the other HDD and all peripherals to try install?

    If installing to UEFI have you correctly formatted UEFI Bootable USB Flash Drive - Create in Windows

    If this is a Win8 PC being installed to UEFI, did you disable Secure Boot in BIOS setup, enable CSM, disable Legacy BIOS?

    Have you tried to Bypass UEFI to Install WIn7?
