  1. Looking for help from someone who knows BCDEDIT very well


    I won't bore you with the lengthy details of what I am trying to accomplish, but the short version is that I am trying to recreate a very specific BCD file from scratch.

    Specifically, I want to create duplicates of 2 BCD files that are found on a Windows 10 Consumer Edition DVD. Even more spefically, this MUST be the BCD files that are located in \boot and \efi\microsoft\boot on the dual architecture Windows media (it has both the x64 and x86 editions on it).

    I have worked out all of the commands that let me recreate these BCD files from scratch with the excetion of the very last section that looks like this:

    Device options
    --------------
    identifier {7619dcc8-fafe-11d9-b411-000476eba25f}
    ramdisksdidevice boot
    ramdisksdipath \boot\boot.sdi

    Nowhere on the internet can I find anything and Microsoft's own BCDEDIT reference documentation says nothing about this.

    Normally the settings ramdisksdidevice and ramdisksdipath appear under a section called ramdrive (if memory serves correctly) rather than Device options and it references a completely different GUID on the "identifier" line.

    I know I'm pushing my luck in the hopes of finding an answer, but does anyone have any ideas on this?

    NOTE: Yes, I am aware that I can simply copy these 2 BCD files from the original media, but I have a specific purpose in mind that requires creating these from scratch using the BCDEDIT command line.

    Should you need to see the above section in context, below is a complete copy of one of those BCD files:

    Code:
    Here is the same file but with a switch that displays the output with all the guids enumerated:

    Code:

    Disabled Hyper-V using BCDedit

    It looks to me like you have set the default boot entry 7f416673-xxxxxx. I will assume, for now the correct default boot entry should be
    7f416671-xxxxx.

    If you agree this may be the case then there is a bcdedit command to change the default boot loader.

    Try using the command below to see how it looks. Be aware, the Guid numbers can be copied and pasted. If you type bcdedit first, you can copy those from that listing.

    bcdedit /default /?

    Examples:

    The following command sets the specified entry as the default boot manager

    entry:

    bcdedit /default {7f416671-8242-11e9-952c-f625ea39d281}

    Use the correct GUID for your system..

    One problem bcdedit has right now is we can no longer use the command bcdedit /enum which would show all the entries in the store. This is why the 7f416673-xxx is not showing in the list.

    Note: There is a possibility the Recovery Tools were set as the default boot on purpose. If your system will not boot with the 7f416671 number you might try the 7f416675 GUID number, or even try that one first since it shows as no Hyper.
