Hi everyone! I've been asking a lot of questions regarding HDDs and installing OSs so I apologise if this is repetetive. I have a numbrer of queries: 1.) I have an old 160GB Seagate SATA HDD. It has Windows XP installed on it. My newer HDD is a 1TB Seagate which has Windows 7 on it. Is it possible to remove all data from my older HDD (including the OS) and use it as additional storage on Windows 7? 2.) If both the SATA devices are connected to my PC in their present state (one having XP and the Other Win 7), which HDD will my computer boot from? 3.) My Windows 7 is set to AHCI and XP to IDE. So when I connect my older HDD I have to change my SATA Storage Type from AHCI to IDE for Windows XP to boot. When I install Linux, will there be an option for AHCI so that I can dual boot without having to change BIOS settings every time? 4.) During Linux installation, if both my HDDs are connected, will they show up separately? Thanks.
