I done dual booting before but on two different drives, now I am thinking about partitioning up 2 320GB HD's in a Raid 1 set up, what I am not so sure of is when I do the first installation, in this case XP Pro, will I be able to partition up the drive before the installation starts or will I have to do that after the installation been done? If I am not mistaken you should start with the oldest OS first when doing a dual booting, right?
Also, would you advice against using the same drive for 2 OS, or is that ok? I am just going to have the XP available if I encounter a game that I might not be able to play in my main OS, which is going to be Win7. Any other programs I have is running fine in Win7 so it will only be for the odd game.
Secondly, this time I am going to disconnect all my other HDD's when I do the installation of my OS, since last time I had them on and seem like I got some system files on a drive where they weren't suppose to go. Anyway, the question I have is once I got my new dual boot up and running, can I then add the HDD's that I have my old OS on in a Hot Swap bay and wipe the HD clean without in creating a conflict (since there is an OS on it and not sure if it will try and start when connected to an already running OS or not? Actually, to add to this, one of my present drives, without an OS on, is showing as an Active drive in the Computer Management screen, if that drive would be inserted in a Hot Swap bay later, would it still come up as an Active drive, even if it is like I just switched on an external drive?). Hopefully that makes sense!
Lastly, what kind of software would you recommend using when wiping the disc's, since I want to make sure it been properly cleaned so no one can get to any data that has been on them, i.e. online banking etc.
As always, any advice/suggestions will be greatly appreciated!
