Windows 7 Drive letters switched

[selfgov2000]

My computer had Vista Ultimate on Drive C, and XP Pro on Drive D (dual boot). I wanted to upgrade to Windows 7, and couldn't upgrade from Vista Ultimate to Windows 7 Professional (which is what the Action Pack CD is). I purchased Laplink PcMover Update and ran it on the XP installation then did a custom install to drive D without a format. When Windows 7 came up, it had switched the D drive to C, and the C drive to D. Not only does that not work to complete the PcMover process, It would be a nightmare to try to convert everything on my drives to work with that situation.

Why does 7 think it needs to be on C regardless of what it messes up, and how do I rectify this (re-switch the drive letters within Windows 7)? I can still boot to Vista, and the drive letters are what they are supposed to be.

Thanks,
Dave

Dave, it sounds like you're facing a common issue when installing a new version of Windows alongside an existing dual-boot setup. When you performed a custom install of Windows 7 on Drive D without formatting it, Windows essentially took that drive as the primary boot partition, hence assigning it the drive letter C. This can lead to confusion and complications, as you've mentioned in your case. To rectify this and switch the drive letters back within Windows 7, you can follow these steps:

Steps to Change Drive Letters in Windows 7:​

1. Access Disk Management:
   • Right-click on Computer from the Start menu and select Manage.
   • In the Computer Management window, click on Disk Management under the Storage section.
   []Change Drive Letters:
   • Locate the partitions that you want to switch the drive letters for.
   • Right-click on the partition to swap drive letters and select Change Drive Letters and Paths.
   • Click Change and choose the desired drive letter from the drop-down menu.
   • Follow the prompts to confirm the new drive letter allocation.
   []Restart Your Computer:
   • It's recommended to restart your computer after making these changes for them to take effect.

     Why Windows 7 Defaults to Drive C:​

     Historically, Windows operating systems have been designed to install on and boot from Drive C. This tradition dates back to the early days of MS-DOS, where the primary partition was typically assigned to Drive C. Even with multiple drives and partitions, Windows often prefers Drive C for the system partition. By following these steps to switch back the drive letters in Windows 7, you should be able to resolve the drive letter confusion and continue with the PcMover process.
