I've asked several questions lately and I appreciate your indulgence. I just want to make sure I do this right, and I'm fuzzy on one aspect.
I currently have Vista Home Premium on a single drive in my system. Since I'm moving to Windows 7 Pro rather than Windows 7 Home Premium, I'll have to do a clean install. I've a lot of programs and data so my approach will be to take my current C drive with Vista out, put in a new drive, load Vista on it, and then do the upgrade to Windows 7 on that drive. Then, I'll put my original Vista drive back in as a secondary drive so that i can take my time moving data over to the new Windows 7 installation.
I'm doing it this way so that I have a boot sector on C for Windows 7, and a boot sector on D for Vista, so that if I have any problems with the Windows 7 install, I can always revert to the Vista drive and keep up and running. I thought about a dual boot with Vista on C and Windows 7 on D, but if I do that and C fails at some time down the road, I wouldn't be able to boot into D because the boot loader would be on the failed drive.
If all that makes sense, here's my question.
Back in the day, we would determine through cabling, or strapping, which drive was C and which was D. I'm unclear how that works with current systems and SATA drives. Once I'm up and running on Windows 7 on the single, new drive, which of course would be C, and I put the Vista drive back in the system, will the system automatically assign that drive as D, or do I need to do something to accomplish that?
I saw a reference to making a drive "active" and wondered if I would have to do some designation as to which drive was C, and which was D.
