have just installed Windows 10,(Oh what fun that was) on a brand new SSD with the view to keep my Windows 7 SSD intact.
I was hoping that once I reconnected all HDDS that on boot I would be given the choice whether to boot to 10 or 7 but it booted straight to ten. I could have course just keep disconnecting and reconnecting the SSD's dependent on what I wanted to do but i was hoping for a simpler solution. Is there one?

I am hoping for confirmation that a solution offered elsewhere is the way to go.

This involves opening the CMD with admin and typing:
diskpart
list vol
sel vol 4
assign letter=S
exit
bcdboot E:\windows /s s: /d /addlast
diskpart
sel vol s
remove
exit
exit

Using info from here with e being the drive that Windows 7 is on.

i was doing this with 2 hds.

one had vista 32 and the other had windows 7.

i just hit f10 upon booting to get into the bios.

there, i just selected which of the 2 hd's i wanted to boot.
 
I have 3 way boot on one disk 7pro,10pro,10oem and when I boot (without using f10/f12) windows allow me to select which I want, via choose an operating system menu

I installed 7 then the two 10's all as custom installs , I assume I could have custom installed 10 on a second drive, having 7 drive visible as I made the install.

But beware of making the second disk known in a common uefi, you can expose yourself to Anniversary update type problems where you update 10 and it decides to change other drives to unallocated status ... so isolation (terrorist cells) maybe best policy, and make the choice with f10/f12

I do not know about command you propose
 
The above commands did not work as when I booted or rather tried to boot into Windows 7 I received this message. Not sure what to do to resolve this and try and as for using the F8 key to select boot. I did not think of that. I tell you this getting on in years coupled with a medical condition don't half kick the bejeezers out of one's cognitive abilities.
Can I sort the dual boot issue out or have I buggered it?

This may not be a route you want to follow but it worked for me in the dim distant past.

You can install Linux and it will offer you options as to what OS you want to boot on start-up.

That could possibly be caused by the fast startup setting in Win 10, hopefully following the steps on-screen has got you back in.

Turn off fast startup as in the guide I posted above and see if booting between the two works alright using disk selection at bios.
