I currently have a PC with a single drive, with WinXP installed. I will soon be adding in another drive to this PC, which had Win7 installed on it (while it was in another machine).
When the PC starts up, will I automatically get an option to choose which drive to boot off of or do I need to do something to set that up?
I am guessing that regardless of which OS I boot into, I will be able to see the other drive. Is that so?
How does installed software work in such a scenario? For example, let's say I boot into Win7 and from my WinXP drive I run some software that was installed under WinXP. Would it be able to run? I was just thinking about something like WinXP registry settings that might be required to run the app. Would those be available if I didn't boot into WinXP? If I install the same software under both Win7 and WinXP, would that cause any issues or are those two drives basically completely separate?
