I recently installed Win7 Ultimate on the second drive of my main computer, but running XP Pro as the main OS. The Win7 partition was "G" in XP and when re-formatted using Acronis Disk Director. However, when booted into Win7 it is running in C Drive and the other partitions go up the alphabet by one letter. This is the first time I have used dual-boot - is this normal?

I intend keeping XP as the default OS for a while, at least until I have Win7 running the way I want, and there are probably advantages running Win7 also on Drive C - particularly if/when I remove XP. However, if I change drives E, F & G in Win7 back to D, E & F (as they were in XP), will that affect anything when I boot back into XP :rolleyes:
 

When setting up a dual-boot system like you have, where you have Windows XP as your primary OS and Windows 7 Ultimate as the secondary OS, some changes in drive letters between the two Windows versions are normal. Here's why this happens:
  1. Drive Assignment by Windows: Each version of Windows assigns drive letters based on its own configuration and the detected drives during boot. So, in your case, Windows XP assigned the drives differently compared to Windows 7 Ultimate. This can result in a discrepancy in the drive letters when you switch between the two operating systems.
  2. Changing Drive Letters in Windows 7: If you decide to change the drive letters in Windows 7 to match what you had in XP (e.g., changing E, F, G back to D, E, F), it can cause a few potential issues:
    • Installed Programs/Paths: Any installed software or programs that rely on specific paths may be affected by this change. If the programs were installed under the new drive letters, they might not work properly after the change.
    • Registry Entries: Windows stores many settings in the registry, including information about drive paths. Changing drive letters can disrupt these settings and might lead to issues.
    • Boot Configuration: It shouldn't affect the boot process directly, but it's always recommended to be cautious when modifying drive letters, especially when dealing with multiple operating systems. To address your concern about changing the drive letters in Windows 7 back to what you had in XP:
    • Switching drive letters in Windows 7 should not directly impact Windows XP. Windows XP has its own drive letter assignments, and changing drive letters in Windows 7 should not affect the drive letters you had in XP unless you are modifying shared partitions. Recommendation:
      • If you plan to continue using both operating systems for a while, it might be best to get accustomed to the new drive letter setup in Windows 7.
      • Changing drive letters back and forth can lead to confusion and potential issues, so keeping the current setup as it is might be the most efficient approach.
      If you have specific software or scenarios that depend on certain drive paths, it's essential to consider their compatibility when changing drive letters. Additionally, always backup important data before making significant changes to drive configurations.
