    If you can use Seatools, you can use GWscan - Try That, it will detect bad sectors. You can also use ViVard to do a full Smart Remap - It's a risky procedure, but I've done it a few times to full success. Sometimes the drives have too many read errors for the OEM scanners to fix, ViVard can fix them all. Seatools and GWscan it won't even try to fix it if there are to many errors.

    I ran ViVard, but it didn't detect any errors. I also noticed that there were no bad sectors, but the file structure is still corrupted.

    Ok, it was acting like the drive can't be read, something else corrupted your Bootloader. The Bootrec /Scanos is acting like Windows 8 has never been installed. Is the directory tree still intact inside? You can use Hiren's "Mini-XP" to see if you can read the drive, and you can either copy your data files out to a safe place, or to a different folder on the drive.

    If it's not a drive error, it may be irrecoverable, Windows 8 can only repair itself when it finds itself, and it's not finding your OS. So something important got deleted or corrupted. Usually it is that Winload.exe file - Look, try this:

    boot to Hiren's and choose Mini XP. Open Explorer, see if your drive is still there and readable. If it is...

    Do a search for Winload.exe - See if there are any dupes of the file, you are looking for the version of the file that has the earliest date of creation, and we want to copy it into the folder that contains the one with a later creation date. Keep both files, just rename the one you are replacing.

    I'm wondering at this point if even there. I'm checking for the location right now, in my system (32 bit) it's in the System32 folder, on 64 bit systems, not sure if it's in the same place. But the file should be 1040kb - If yours is a different size, it may have been replaced.

    If this doesn't do it, get ready to reinstall Windows 8, you can use Mini XP to move all of your stuff to a safe folder and then you can delete the rest of the folders on the drive, since the drive is OK, it should be good to use for a fresh install.

    I have a similar issue. I now have to boot from CD in order to load my system.

    This is what happened. I installed a (2nd) new hard drive identical to the one I have (Seagate - 1TB Sata III 7200 rpm 3.5")
    And then started my desktop PC, (Running Win 8.1) went into disk management and did a complete format of the the drive. Before doing so the type of drive selected was MBR and I named it JMA D:
    Afterwards, I made the mistake of choosing to "Mark the partition as active". When I went to reboot, the computer did not find an operating system. I did some research and unplugged the new drive, used the bios to load from CD and was able to log in. Shut down and then was able to start normally. Shut down again, plugged in the new drive, used disk management to reformat the new drive and then put it online. This time i did not "Mark the partition as active". Originally my C: drive was shown as disk0 and the new disk was show as disk1. Now they are reversed. The C: which is "Active" had made a system reserve space. I looked and saw a temp directory was made. I "Explored" the c: drive and saw it also had a Temp file, which contained older boot info. I moved the new system reserved space folder marked Temp into the C:temp file and then formatted the system reserve partition.
    (Dumb, Dumb Dumb, I know now.)
    Anyhow, the computer will only boot if I use the Windows 8.1 disc, while pressing F11, and telling it to load from the c: drive.
    If i do not do that, it ask which removable disk drive do I want to load from?

    I have tried using the advance repair tools, and it looked like it "Corrected start up problems" but will only restart correctly one time, and then goes back to looking for a disc each time I restart.
    Is there anyway to corrected the problem with out having to reinstall my OS on Drive C:

    I tried Bootrec /Fixmbr from the startup disc admin command prompt and it shows problem fixed, but it is not fixed.

    I'd hate to have to reinstall all my programs again. Click image for larger version

    edit: Note that these instructions only work if the hard disk has an MBR (Master Boot Record) partition table. Here is some info about MBR and GPT partition style: link

    Step One:

    Change the secondary drive to the primary drive.

    Step Two:

    - Boot the computer using the Windows 7/8/8.1 installation media.
    - On the first screen, press SHIFT+F10 to bring up command prompt.
    - Run the following commands at the command prompt.

    bootrec /fixmbr
    bootrec /fixboot
    bootrec /rebuildbcd

    The bootrec /rebuildbcd command will search for Windows installations not included in the Boot Configuration Data (BCD) and then ask you if you'd like to add one or more to it.

    Note: If you receive the error message "Element not found" when you execute the "bootrec /fixboot" or bootrec /rebuildbcd command, then you must first mark boot partition as active with diskpart. Note: If there is a partition labeled "System Reserved", it is the boot partition, if not, the Windows OS partition is the boot partition.

    diskpart
    select disk 0
    list partition
    select partition # Note: Select the "System Reserved" partition (if you have it) or the Windows OS partition.
    active
    exit

    genet,

    Thank you for the response.

    Do you mean i need to simple switch the connectors that hook up to the Sata 6gb/s connectors on my Mother board first? Then try to reboot?
    Or is there some way in Disk Manager. (None I see)

    Awaiting your advice!

    Thank you in advance!

    Yes, step one. Then step two.

    Okay,
    So looks like the drives are corrected, and then when I ran the:
    bootrec /fixmbr
    bootrec /fixboot
    bootrec /rebuildbcd

    They all showed they were corrected!

    So it is fixed, if I use the shut down. Then it starts normally.

    But when I use "Restart" it always goes to the screen that shows my 2 external disk drives and ask me to select one for booting.
    The only way to get the choice to load from the C: drive is to Ctrl-Alt-Del-, and then tap F-11 key in order to show all my boot devices i.e, Dvd/Cd, USB ports and the two hard disks.

    Also note, that if I choose to "Cntrl-M" and enter Bios, all I see is the 2 hard drives (unconfigured) and really no way to make any changes there. X58a-GD45 Marvel bios

    Any further suggestions?

    Here is the new configuration in disk management and I also ran checkdisk. The results look good as well.
