    Dwarf,
    My question is still why the author chose to use UUID instead of
    GUID. I feel like the author would be the only person qualified to answer why he made that choice.

    I am well aware of the definitions, per se.

    Lol, no problem. I guess that Limneos is the only person to answer that particular question. As far as I can make out, they are pretty much interchangeable, but as for why he chose one form over the other, only he can answer.

    Ok I think this is going to help me out later since I'm not by my computer at this time. I have a question though. I think Windows 7 is trying to boot from my E: drive but my "system" is setup on the C:. If I run through the BCDedit/ and I see that this is the case how would I go about getting the "boot" back onto the C: drive?

    Thanks!

    BuildnCastles,

    Shut off your computer.

    Turn on you computer.

    Immediately, and continuously, tap the F8 key until you get to the "Advanced Menu Options" screen.

    Choose the top choice, "Repair your computer"

    You will get a "System Recovery Options" window.
    Next you way along and sign in with your admin password if you would like.
    Finally, you get another menu.

    Choose the top choice again "Startup Repair"

    See if this doesn't solve your problem.

    Ok I ran "startup repair" and this didn't work. I'm noticing that it states that "Operating System: Windows 7 on E: Local Disk ". My windows 7 IS NOT installed on E: but it's installed on C: So to make myself clear C: was the main SATA drive used that I installed Windows 7 on originally.

    When I run /bcdedit the following pops up:

    Windows Boot Manager
    Identifier: {bootmgr}
    device: partition=C:
    description: Windows boot manager
    locale: en-US
    inherit: {global settings}
    default: {default}
    resumeobject: {c767c984-c249-11de-8b9d-c7ee4708438f}
    displayorder: {default}
    toolsdiplayer: {default}
    timeout: 30

    Windows Boot Loader
    Identifier: {default}
    device: partition=E:
    path: \Windows\system32\winload.exe
    description: Windows 7
    locale: en-US
    inherit: {bootloadersettings}
    recoveryseq: {c767c984-c249-11de-8b9d-c7ee4708438f}
    recoveryenab: Yes
    osdevice: partition=E:
    systemroot: \Windows
    resumeobject: {c767c984-c249-11de-8b9d-c7ee4708438f}
    nx: Optin

    Is this setup correctly? Please help.

    I ran Diskpart, lis vol and the following comes up as well:

    Volume#/Ltr/Label/Fs/Type/Size/Status
    Volume 0/F/DVD_ROM/UDF/DVD-ROM/3094MB/Healthy
    Volume 1/C/System Rese/NFTS/Partition/100MB/Healthy
    Volume 2/E/blank/NFTS/Partition/465GB/Healthy
    Volume 3/D/Tera/NFTS/Partition/931GB/Healthy

    I don't understand but my D: drive is my 1tb hard drive? When windows was working it was drive letter E:

    It still is looking at E: when trying to find system restore points; I know it used to pull the system restore points from the C: drive though. Shouldn't it be looking at C:? Is this the reason why it can't boot up? I can get to the login screen but it's completely black. Thanks for all the help!

    bcdedit /set {4c21825f-e04b-11dd-b760-00195b61617a} numpoc 2
    NOTE: This adds the 2 CPU Core support during boot, like you do in msconfig.
    numpoc 2 = numproc 2
