    Help!! Error loading operating system


    There is a problem with my old PC (Windows 7 x32, Intel duo core processor, 2.5 GB RAM) which was custom or assembled, it says 'Error loading operating system' and I have been trying to fix it for hours..
    Earlier when this happened (A lot of times), I fixed it from the Repair option when I press F8 contineously, but when i keep on pressing it, nothing happens (System Repair Blackscreen does not come).
    It happened when I pressed the restart button in my CPU when my PC was stuck for a long time, instead of waiting and manually restarting.
    The biggest problem is that I LOST my Windows 7 CD. All I have now is just a USB with backup files.
    When I put on the USB while booting, it says 'BOOTMGR is missing, Press Ctrl+Alt+Del to restart' but it shows the same thing when I restart.
    When I pressed F10, It showed the Boot Option Menu, it had 3 options:
    • SATA: Optiarc DVD RW AD-72203
    • Realtek Boot Agent
    • MBIC SS MMoser Baee Disk PMAP (That one is my USB)
    These 3 didn't work either....
    So, Please help me to find a way to fix it.
    Ask me if you want any more information.
    Thanks...

    Hi

    Either a corrupted MBR or a failing hard drive can cause that error message. I would suggest ;

    1. Replace the SATA data cable of the hard disk.

    2. Run a "Long Test" with "Seatools for DOS" and verify disk's health condition.
