    Some help with dual booting


    Hi,

    I bought an HP with Windows 8.1 installed. I put in a second hard drive, unplugged the drive with Windows 8 installed, and installed Windows 7 on that drive, then plugged back in the Windows 8 drive.

    I installed EasyBCD in Windows 8 and did my best to remove all the non-essential drives, and left Windows 7 & 8, with Windows 7 at the primary boot. I also disabled a few things in the BIOS which I've read on other posts, enabled legacy, etc.

    Sometimes I will get the GUI boot manager with Windows 7 & Windows 8 listed. If I choose Windows 7, it goes to the black & white boot manager, with only Window 8.1 listed. Other times it goes straight to the black & white boot manager, with only Windows 8.1 listed.

    How can I get it such that both OS are listed, and, I can boot into one or the other? A couple of times I messed around with some boot settings and other things and was able to boot into Windows 7.

    But, I just want a boot manager to list both OS and allow me to boot into either one.

    Any help would be appreciated.

    Thank you.

    The directions for how a system boots are in the BCD store. To be able to see those directions, we need to get a copy we can read. You may start an Administrative Command Prompt Window and type in (or copy and paste) the command below. Then attach or zip and attach the resulting text file put on your desktop by using the paperclip on the Go Advanced replies.

    bcdedit /enum all > %userprofile%\Desktop\bcdlist.txt

    Thank you very much for your reply. I am attaching (I hope) the file you have requested. If not, let me know please and I'll try yet again.

    What it looks like is you seem to have the USB Floppy/CD listed first in the Firmware Boot Manager. Not sure exactly how that happened, but is that device still connected?

    Since you have two entries in Firmware Applications for that same device, and one is the version shown first in the fwbootmgr, I would suggest you delete that entry from the BCD Store, but not quite yet.

    You do not show a Boot Loader for Windows 7, so possibly the entry for the USB floppy is being used to boot Windows 7. You do not needto enable Legacy in the Bios when you install Windows 7. The SP1 version will install fine in UEFI, but will not support the Windows 8 secure boot so you have to enable the CSM to allow it to boot. In your current situation, you will need to leave the Bios setting the way it is since Windows 7 is probably installed as Legacy.

    I do see a firmware application for Windows 7 so perhaps EasyBCD has set this up in a way I don't recognize. You do show a setting to display a Boot Menu, so perhaps that is why you are getting a boot menu with only one OS shown.

    A picture of your Disk Management window might help, but if you run EasyBCD from Windows 8.1, it might be able to set up the boot, or using a bootrec /rebuildBCD command from the Command Prompt in the Recovery Options might add Windows 7 to your Boot Menu.

    The important thing right now is if you choose the Windows Boot Manger as the boot device, it will boot you into Windows 8? We may need to clean out some of the clutter depending on what the Disk Management picture shows.

    Thank you again for your input. I am attaching a copy of my Disk Management screen per your request. I hope it helps.

    Also, I did not find any options for CSM in the BIOS. Additionally, EasyBCD was installed under Windows 8.

    Thank you.

    We know you did install Windows 7 as a Legacy install. If you are using a 32 bit version, as in the DVD drive, you have to install it that way.

    Is the USB Floppy/CD device still connected, and what is it?

    If you use the Boot Device Menu and select either a Windows Boot Manager, or the 500 GB hard drive, I assume it boots into that OS normally?

    What does EasyBCD show when you try to add the Windows 7 boot with it. I haven't used that utility in a while, but there may be an option to add the Windows 7 OS.

    If EasyBCD won't work, do you have the ability to boot into the Windows 8 Recovery options and the Command Prompt?

    Your Recovery Image partition shows with a D: and as OEM. Is that the way it was originally or did you use something like EaseUS to change some partitions? The fact it shows twice may be a Disk Management situation, but notice, only one shows as NTFS.

    Hi,

    Thanks for your reply. I'll try and answer the best I can.

    I unplugged the Windows 8 drive. Then, when booting, I hit F9 and told it to boot of of the legacy CD. Although there is only 1 CD/DVD, so maybe it was the way the computer was seeing it?

    I then installed Windows 7 on the second drive. The new drive was assigned letter G:.

    In EasyBCD, I told it Windows 8, C:, and Windows 7, G:. This was a manual change, and I basically removed everything else.

    IF the graphical boot manager loads, I see a Windows 7 & Windows 8. But, either choice brings me to the black & white boot manager with Windows 8 only.......sometimes messing with the keys I only get the black & white boot manager, again, with only Windows 8.

    Does this help at all? If not, I can try to be more detailed.

    Thanks!

    I really need an answer as to what the USB Floppy/CD is and whether it is connected or not... It is not normal for the device to be listed first in the Firmware Boot Manager. If you are running some type of Windows to Go system with an external drive being involved, please explain.

    Firmware Boot Manager
    ---------------------
    identifier {fwbootmgr}
    displayorder {c55adadf-524d-11e4-826c-202564d76696}
    {bootmgr}
    {default}
    {c55adae0-524d-11e4-826c-202564d76696}
    {f8519d3e-524e-11e4-826d-806e6f6e6963}
    {f8519d3f-524e-11e4-826d-806e6f6e6963}
    {f8519d40-524e-11e4-826d-806e6f6e6963}
    timeout 2

    Firmware Application (101fffff)

    identifier {c55adadf-524d-11e4-826c-202564d76696}
    description USB Floppy/CD
    I will check to see if I can find out how the configuration is supposed to look using a Legacy install. But right now, the Windows 7 entry when booting the way you did to get the BCD listing does not show an install correctly.

    I may be quiet for a while trying to determine if I can find a way to get your configuration to work.

    I set up the system as you did, with a Legacy Windows 7 install on a second HDD. I then used the Bootrec /rebuildbcd to add the Windows 7 to the Windows 8 BCD Store, after I had booted into Windows 8.

    Everything looked fine, but when booting to Windows 7 it says the drive is not accessible and will not boot. I can boot to either install if I choose that install in the Bios. But once it goes through the normal boot, it will not boot into Windows 7 without the error even after the system is rebooted to do so. I am guessing the BCD Store is not set up to direct the boot to the boot manager on the Windows 7 drive.

    So I am going to see if I can find a way to get the Windows 7 boot menu option to point to a Boot Manager instead of a Boot Loader, but I don't have much hope I have the knowledge to do that.

    Thanks for the reply. Sorry if I did not answer your question.

    >>> I really need an answer as to what the USB Floppy/CD is and whether it is connected or not

    That is basically the CD/DVD that came with the computer. SATA device. I put it as the first boot device in the BIOS when trying to install Windows 7 on the second drive. I was under the impression that, like other windows, it would boot from it, but it did not. I had to hit F9 and select some Legacy CD device. I just never re-ordered the devices.........do you think this is the cause?
