    Windows 7 not detecting Hard Drive


    So I built a computer 2 months ago, and was doing fine until one night it turned off suddenly, and when I tried to log in it gave me a black screen. So after hours and days of trying to fix it, I decided to use a program to save the important data from the hard drive (Seagate Barracuda 1TB) and format it so I can do a clean install.

    I formatted it and was healthy and fine, so I attempted to install Windows 7 Ultimate x64 via USB boot. When I got to the step where I was to choose a hard drive to install it to, my hard drive was not shown. So I again searched for an answer, where I stupidly tried to "Clean All" in disk part. I waited a very long time (6 hours) and it did not look like it changed, so i Ctrl-c'ed and stopped it. Now I cannot explore the hard drive, and it does not show up in windows. If I go to disk management, it says, "You must initialize a disk before Logical Disk Manager can access it." Image attached. And right after it says, "The operation cannot be completed because the disk is being cleaned". I cannot remove the USB cord that connects to the hard drive as it says it is in use and i do not want to damage it.

    I am confused and tired and am getting frustrated. Please help me if you can and thank you.
    I can supply more pictures and information if needed.

    My Specs:

    Intel Core i5-3570 - CPU
    Gigabyte GA-H77M-D3H LGA1155 - Mother Board
    Corsair Vengeance 8GB (2 x 4GB) DDR3-1600 - Memory
    Seagate Barracuda 1TB 3.5" 7200RPM - Storage
    Gigabyte Radeon HD 7870 2GB - Video Card
    Antec 520W ATX12V / EPS12V - Power Supply

    Thank you in advance.

    Hello Theog,

    Firstly, thank you for your reply. It has successfully formatted my hard drive, and is now readable by my computer.

    However, I am following the steps in the first link you gave me, and am stuck at step 6. It tells me that I should have 3 partitions. When I follow step 5, I am only given the system partition and the other partition which holds the rest of the space. I am missing the "MSR (Reserved)" partition shown in the screenshot. I am confused on what to do here.

    Thank you in advance.

    Reboot the PC, than initialize.
    Delete all partitions in Drive Options.

    Thank you for you reply,

    When I click on new it only makes 2 partitions,
    Disk 0 Partition 1: System Reserved (100 MB Total Size) (86 MB Free Space) Type: System
    Disk 0 Partition 2 (931.4 GB Total Size) (931.4 GB Free Space) Type: Primary

    I have booted it as UEFI, I have deleted all partitions before pressing NEW, and I have no idea what to do.

    It looks like it's installing normally to an MBR disk rather than in EFI. Do you have Legacy BIOS enabled?

    I'd just click on Partition 2, then on the other drive option to Format, then click Next to see if it proceeds with Clean Install Windows 7

    I have got a question, do I have to boot via UEFI? or can I just legacy boot it? What are the benefits?

    Some reading to understand UEFI which is relatively new and presents a whole new set of problems with installs and repairs here we are only now getting familar with:
    The 30-year-long Reign of BIOS is Over: Why UEFI W... - Input Output
    Technical Note: UEFI BIOS vs. Legacy BIOS - YouTube

    Many users here have had problems that were resolved only by installing with Legacy BIOS as described in Bypass UEFI to Install WIn7.
