Dual boot help

I have done a fresh install of Win 10 on a SSD. Then I have a HDD with Win 7 upgraded to Win 10 which I use for games. Everytime I boot using the HDD, it currups the SSd making it unbootable. I had to reinstall Win 10 on the SSD... what am I doing wrong?
I notice that in the SSD, there is a "system reserved" drive while on the HDD, there's none. Could this be the reason?
Please help. Ta

When you installed the ssd did you have the win7 disk also on line ? if you did then should also get a boot menu that asks which of the 10's you want to boot.
I have two 10's on different partitions of a ssd which play happily together - BUT I have not updated to Anniversary which is known to cause issues making other partitions appear unallocated.

No.

I updated the Windows 7 (on HDD) to Windows 10, then I unplugged the HDD, plugged the SSD, and installed Win 10. I then plugged them both and I select on bios which drive I want to boot.

Another idea
Try disabling fast boot on the ssd boot or both, I have had some unexpected chkdsk demands when swapping from one 10 to another and believe (read somewhere) that fast boot intentionally leaves some file descriptors open that can subsequently cause issues if you access that disk whilst booting the other.
(I have also had issue where restore points disappear from one boot after accessing the other, so be aware of that down the line - I guess I will just take secure copies with macrium instead)

This is giving me a headache. I just reinstalled win 10 4 times now. I wonder how many activations I can make before it gets blocked by MS.
The only aolution I can think of is to use a 5.25 cradle so I can easily swap HDD / SSD without opening my case.
