well you will need to do a fresh install for each OS you plan to use on that new MB. I install the OS when only one drive is connected. I use my BIOS to select the OS to boot. I default the most used OS to boot by default.
If I fresh install win 7 on SSD & then connect the HDDs with already running win7& XP, would it recognize the OS already installed & BIOS will give choice of OS?
Thanks for taking time to help, I appreciate it.
Also, SSD with only OS installed or OS & program would be more rewarding(for better performance?
