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:
