Windows 7: Dual Boot with XP and Win 7 on 2 HD's

Dual Boot with XP and Win 7 on 2 HD's

Currently my C: drive has XP on. If I go to the dual boot with win 7, it will be loaded on the D: drive. Is there any reason to flip flop the drive letters, so Win 7 (which I will be using 80% of the time) will have its main drive as C: ?

On another note, since I have 2 hard drives, what if I removed the C: drive with XP on it and did a clean install of 7 with the other blank hard drive. Then after 7 is up and running, add the drive with XP back into my computer. I just want to guarantee that when I install 7 I don't screw up my XP system.

Removing the Xp HD during Win7 install gives you the cleanest Dual Boot configuration, since it boots via the BIOS and doesn't intertwine the HD's as a Windows-managed Dual Boot (created by Win7 when both HD's are plugged in) does.

After Win7 install, plug XP back in and set your preferred HD to boot first in BIOS, after DVD drive. Then use the BIOS shortcut key for Boot Menu given on the first bootup screen (often F8, F10 or F12) to boot the other HD instead.

Neither method will hurt XP, although if it remains plugged in during Win7 install, the MBR on XP will be updated to manage the Dual Boot with Win7, making it harder to extricate XP later without special steps which we can help you with.
