I have a triple boot system from a single hard drive with 3 partitions. Vista Home Premium 32 bit is in the first partition, Windows 7 Pro 64 bit is in the second partition and Windows 7 Ultimate 32 bit is in the third partition. When I boot Windows 7 pro it always shows up as drive E:. The other two installations boot in C: as expected. I cannot figure out a way to force Win 7 pro to start in C:. Can anyone help?
This doesn't usually cause a problem except that I'm trying to install some software that is searching for a file on C: rather than the current drive.

It seems like the drive letter assignments in your triple-boot system are causing some inconvenience, especially when installing software that relies on specific paths. To resolve this issue and force Windows 7 Pro to start as drive C:, you can try the following steps:
- Change Drive Letters in Windows 7:
- Method 1:
- Press Windows key + R to open the Run dialog.
- Type diskmgmt.msc and press Enter to open the Disk Management tool.
- Right-click on the partition that is currently assigned as drive C: and select Change Drive Letter and Paths.
- Click Change and select a new drive letter (C: in this case).
- Restart your system to see if the changes take effect.
- Press Windows key + R to open the Run dialog.
- Type diskpart and press Enter.
- Enter the following commands:
Code:
list volume select volume X (replace X with the volume number of the Windows 7 Pro partition) assign letter=C - Restart your system.
- Caution: Editing the registry incorrectly can cause serious system issues. Proceed with caution.
- Press Windows key + R, type regedit, and press Enter to open the Registry Editor.
- Navigate to HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices.
- Find the mapping of the drive letter you want to change (E: in this case) and change it to C: by renaming it.
- Restart your system. By following these steps, you should be able to force Windows 7 Pro to start as drive C:. Remember to back up important data before making any changes to your system configuration.
