This should be possible, though you might have to handle boot selection manually (i.e. press F10 and then select which disk to boot from). I have never tied this scenario, so haven't gone through the process of attempting to get up a boot menu for this possibility (trying to do this may end up causing cross-contamination of the tow environments).
Tell me, have you considered instead using VM to handle this (i.e. run VMM on one instance and then run the second instance in a VM? It might actually end up being less complicated...
Windows will install the boot menu when you install the second one. It should be seamless but if it isn't boot to your install media and select Repair. I have Win 7 and Win 10 on my NUC6i7KYK.
Thanks! I need to keep the systems separate for legal reasons,
I'm not thinking of Windows 7 and Windows 10, but two instances of Windows 7. I've heard that USB devices can hold software that allows for dual booting between the two Windows 7 instances.
These answers are helpful, but not the entire answer as yet.
Just install Win 7 to the second drive and Windows will give you a boot menu at startup automagically.
Ill give this a try this week.
Please let us know the outcome.
Which is the model of the NUC, you are using?
Cuold you please provied your system information:
RAM Model, HDD/ SSD, BIOS version.
