    Lost Dual Boot Screen?...Lost Windows 7


    I have Vista Home Premium 64 bit and I downloaded 64 Bit RC Windows 7 and did a clean install on another partition of my hard drive. Dual boot was working for about 4 days then all of a sudden it doesnt come up any more. The partition is still there with Windows 7 installed on it but its not booting under it. I go into MSConfig and Windows 7 isnt even being detected, checked the advanced system options in the control panel and it isnt there either.

    Any idea how to recover windows 7? I did not install it from dvd, I installed from Daemon Tools and worked fine.

    Do I need to Burn the image to a DVD and run it on startup if I want to run Windows 7?

    Try downloading EasyBCD and creating a choice for Windows 7

    That is one thing I dont want to do. There should be no reason why I need a secondary program to dual boot when I was able to. Anyone have any ideas on a system setting, not a 3RD part program to fix this issue. If there is no way to doing so then I wont be switching to Seven any time soon.

    You know, you asked how to fix your problem.. And a way was offered to help.

    Personally if you don't want to test 7 and all the things you might have to do to test it.. Don't.

    Hi Blackhawk,

    What does bcdedit reveal?

    Open an elevated command prompt, type bcdedit, then press enter.

    Post a screenshot, like this:

    I have it right this time, sorry for running the command prompt incorrectly.
    But the information still seems like Win7 is missing from the pc.

    Second image is my computer drives. Pavilion Vista is Vista Home Prem., Pavilion Backup is my backup data partition, and Pavilion Seven was where I installed Win7 on.

    Ok,

    I was looking for a screenie for Disk Management, but it looks ok from what you posted.

    Try this:

    Open elevated command prompt, type: (Press enter after each command)

    bcdedit /copy {current} /d "Windows 7"

    It will return a long number in brackets - a GUID, or identifier.

    Type that, including the brackets into the commands below

    bcdedit /set {the-guid-you-got} device partition=F:

    bcdedit /set {the guid-you-got} osdevice partition=F:

    Reboot.

    Hello Blackhawk,

    In addition to SIW2's post, you should also be able to run a Startup Repair from the Windows 7 installation DVD to repair the boot file.

    Hope this helps,

    This what happened when I ran the command prompt. I rebooted, it said Windows 7 was an OS but it ran Vista instead even when i selected it. In the start-up repair do I need to make it into a DVD or can I mount it as an Image on Daemon Tools to run the repair? Do I have to run it on boot or while in Vista?
