    How to add an existing VHD to boot menu? Please help.


    Hello everyone!

    A few years ago I setup my computer with Windows 8/8.1 on the local hard drive C:, just as usual. Then I added to VHDs to th menu, one Win 8.1 for games and one Windows Server 2012 R2 that I use from time to time for virtualization, where I run sort of my training environment.
    Now my computer broke and I had it repaired at a shop, where they put in a new power supply. When I got my PC back on Friday, they said the'd tested it and it would boot to Windows.

    Well, it does, but my boot menue has disappeared. Also, I noticed that system date was Dec 31st of 2017, so there might have been a BIOS/Firmware reset issue. Unfortunately I do not remember if my previous setting was to boot in BIOS or UEFI mode.
    I do not know if or what they did to my BCD and I have a hunch they won't tell me, once I tell them about my problem. (And even if they did, my previous BCD won't just reappear by magic.)

    As all my files still exist I thought it would be an easy job to add the two VHDs to the boot manager menu, but either I did not write down what I did last time or I can't find it. So I went through the internet, trying lots of tutorials and how-tos, but to no avail. One of the last ones was this one from the vendor. No matter what I try, after booting to one of my new boot menu items, the screen just stays black. It may also make a short beep, then reboot, but then the second time in a row it just stays dark. There is no error message.

    I also tried to copy the original, working item, then point it to a VHD, but this also did not work.


    I am probably missing something small, but I really have no idea. So every hint is appreciated here! After spending a few hours Friday night and Saturday on trying to get this running again, I am now here, kindly asking for your help.

    BCD is attached below. Items are:
    1: boot manager
    2: local Windows on C:, as I got it back from the shop.
    3: VHD for gaming. Apparently my config is currently not shown / got lost:
    device vhd=[G:]\VMs\Games.vhd
    osdevice vhd=[G:]\VMs\Games.vhd
    4: VHD with my Windows Server 2012 R2 training environment
    5: Copied #2 and had set
    device vhd=[G:]\VMs\Games.vhd
    osdevice vhd=[G:]\VMs\Games.vhd
    which is not shown for some reason.

    Thank you for your help!

    In an elevated command prompt I have just tried to fix the missing device/osdevice of #3and #5:
    bcdedit /set {d6bce695-d6d9-11e7-8499-ac220bc55fa4} device vhd=[G:]\VMs\Games.vhd
    bcdedit /set {d6bce695-d6d9-11e7-8499-ac220bc55fa4} osdevice vhd=[G:]\VMs\Games.vhd

    returned "The operation completed successfully.", but it still reads:
    device locate=\Windows\system32\winload.exe

    This thread has been moved. Please note that my issue is about native boot, not virtualization.

    Use a free program like EasyBCD > Software Library - NeoSmart Technologies

    and delete every BCD entry ( other than the current OS )

    Mount each VHD and note the drive letter assignment (% = drive letter assignment)

    then from a command prompt (admin) type:

    bcdboot %:\ windows

    it will create the boot entry for that certain vhd.. then you can again use EasyBCD to rename the description of the vhd boot entry...

    I will also note that your BOOTMGR is using bootmgfw.efi
    and your Current OS is using winload.efi

    which means your system has a UEFI system partition.
    Your VHD's are setup to use a Legacy / MBR boot

    I assume these are x64 VHD's > if so > then you can just edit winload.exe to winload.efi
