Can't get dual boot Windows 7 / Windows 10
I'm trying to set up my computer to allow me to dual boot into Windows 7 and Windows 10. I have some critical programs that won't run in windows 10, so I need to keep my windows 7 install available.
I also decided to buy a SSD to run windows 10 on, so I could get better performance. (Since windows 10 runs like garbage if you don't use one.)
I just installed my new drive and installed windows 10. All the tutorials I found online showed windows 10 automatically finding the the windows 7 install (as long as you installed it on a separate partition) and it worked without any problems. However when I did it I had no such luck. Looking around, it appears that this automatic magic only works if you install both OS's onto the same physical drive.
Is this correct? Or is there something I need to tweak, like in my BIOS maybe?
And moreover, how do I manage to actually set up my system to allow me to boot into windows 7 again?
I imagine I could change the boot order in the BIOS, but I'd like a more user-friendly system that doesn't require me to pound the del key every time I switch.
Other info:
The "system reserved" drive from my windows 7 OS now shows up in my PC as the D drive, and my former C drive as the E. I don't actually see any system reserved drive for the windows 10 install when I check Disc Management.
Also I'm concerned about screwing up functionality with changing drive letters.
If this new windows 10 install is on C and window 7 is now E (my D drive is a secondary HDD) then when I run windows 7, wouldn't all the programs I have on there be looking in the wrong location?
I suppose if I have to, I don't mind if E and C swap letters depending on which OS I boot into. Otherwise I guess I could have the windows 10 installed to the E drive? (I have nothing on here yet so it would be easy for me to reinstall it right now.) But I kind of worry that most new programs would default to installing on the C drive instead of the drive the OS is on. Or is that not really a concern?
But the System Reserved partition showing up as a user-accessible drive... That bugs the crap out of me, and has me worried something is going to write something to it and ruin it.
