Final result wanted: Separately boot the two physical drives > Win-10 s/b primary and Win-7 secondary.
Cloned my Win-7 Drive and installed Win-10 using the free update.
With drive cable removed from either drive, Either physical drive will boot.
Booted Win-10 drive.

------------------------
Installed EasyBCD on Win-10 drive.
Made a picture of DiskMgt to see what was active and what was were (drive letters) for each drive.
Used EasyBCD to add a Bootloader entry by referencing Win-7 drive letter.
Examined BCD and bootmgr references both bootloaders with display showing Win-10 first and Win-7 second.
-----------------------
Rebooted system.
Selected F8 and Win-10 drive from MOBO BIOS.
Display showed boot boot menu for Win--10 and Win-7.
Selected Win-10 and booted to Win-10 drive.

-------------------------
Rebooted system.
Selected F8 and Win-7 drive from MOBO BIOS.
Display showed boot boot menu for Win--10 and Win-7.
Selected Win-7 and booted to Win-7 drive.

--------------------
PROBLEM
-----------------
While I booted to the WIn-7 drive, I just received a Blue Screen (NO BSOD IMHO). Could bring up task manager and
shut down or restart system in lower right corner.


-------------------
QUESTIONS
----------------
1) Is it now normal if one goes to F8 (MOBO BIOS disk menu) to then get another menu to select Which drive one wants to boot from? (IMHO seems kinda dumb to have to do it twice),.
2) Am I running into a windows licensing problem since I used WIn-10 free update, and if so how do I confirm?
3) If not a licensing issue, any idea Why the Win-7 desktop is not showing. See below for pic of BCD Store.

4) See Attached txt file of bcd. Noticed the last two line are missing from the second bootloader as compared to first if that means anything?



Thanks beforehand for responses.

First - THANK YOU . I did the free version so far for both learning and trying a
test example.


1) My biggest confusion came from understanding the BCD Store and relating it to EasyBCD.
Took me awhile to recognize there is just one boot manager and a bootoader for EACH item
(physical disk in my case) one wants to boot in the BCD store. Next issue was for the
added drive that the drive letter for that drive needed to be based on how the boot drive (bootmgr drive)
interpreted the added drive active partition. So if the added drives normal active and boot partition
is C:, and this C: drive is relettered to G: when it is referenced from the boot drive where the bootmgr
exists, then the drive entry for the bootloader needs to be G: NOT C:.


2) ALso would be nice if one could display the store after any entry so one can confirm the entry was in fact made.

3) Lastly see my forum post questions here:

NOTE: Post #2 is just a comment.

My POST #1 questions still need an answer.

Re: Post #1 and failure to have access to the Win7 drive, an additional question is:


Does the GUID in the BCD of the Win-7 drive when it is the ONLY drive connected (drive C) need to the
same GUID value when it appears in the BCD of the Win-10 drive as Drive G?
(Note: They are not the same and EasyBCD assigned another GUID when I Added the Win-7 drive.)
