How come I have two versions of Windows 10 installed in my pc?

[Ciaran]

The functioning version is on volume 2. I have two physical disks labeled C: and D: but I also have three partitions in disk 1 (which is drive C: I suppose) and the partitions are: *:System Reserved (status - active & system), C: (status - boot) and an unnamed partition *: (status - none). Disk 2 (single partition) is supposed to be a data drive but its status is active. All partitions are set as primary and NTFS. Is drive D: also volume 2? If it is, why there is no windows directory in the drive? The other windows can't run because the error said there is no winload.exe on it but the file does exist on c:\windows. Does the running windows is installed in drive D: and boot from drive C:?

Based on the configuration you've mentioned, it appears the Boot Manager reads from the "System Reserved" partition which contains essential boot files like BCD (Boot Configuration Data). Meanwhile, your active Windows 10 installation is likely on drive C: as its status is "boot", suggesting it's where Windows loads from.
To understand the different statuses, here's a simplified description:

• Active: This is the main partition that your PC’s BIOS looks for (and boots from) when the computer starts up. The partition marked as Active must contain boot files (i.e., the Boot Manager).
• System: This is the partition where the boot files are stored. The boot partition will contain the Windows and Boot Manager folders.
• Boot: This label means that there is a Windows OS installed in this partition, and the current running OS is in this partition. In this case, you seem to have multiple partitions set as 'active', which isn't typically necessary and can sometimes result in boot conflicts or errors. As for your D: drive or disk 2, if it's intended to be primarily for data and doesn't contain a Windows directory, its status being active may simply be due to improper configuration, rather than a sign of another OS installation. The status of being active can be changed to match its intended use as a data drive.
  Concerning the second Windows version you mentioned: If the OS was previously installed in another partition and that partition isn't present or correctly configured anymore, you might get a winload.exe missing or not found error even if the file does exist in C:\Windows. This may happen for instance if the boot configuration is corrupt or isn't accurately pointing to where the actual OS files are.
  The currently running Windows shouldn't be installed on drive D: as you mentioned there is no Windows directory there. It is instead installed and running from your C: drive, which is also where it boots from since the C: partition status is marked as 'boot'.
  To resolve and clean up your PC configuration:
• Make sure your essential data is backed up.
• It may be best to remove the unused second Windows installation from your boot manager.
• Change the boot status of your D: Drive if it's solely intended for data storage.
  These changes should be done carefully or with assistance from an expert or knowledgeable friend to avoid potential data loss or rendering your system unbootable.

So, how do I remove the unused second Windows and how to locate its directory?

That usually happens if Windows was installed more than once without fully formatting the drive, or if an upgrade or repair installation created a duplicate entry in the bootloader. You might see two Windows 10 options when starting your PC, but they could be pointing to the same system or two separate installations on different partitions.

Great, you've got a solid understanding of the situation! If you want to confirm whether both Windows installations are actually using different partitions—rather than just duplicate boot entries—it helps to check your disk partitions as well:

1. Press Win + X and select Disk Management.
2. Look for multiple partitions labeled as “Windows,” “OS,” or similar. Each will typically have its own drive letter.
3. Right-click each partition and choose “Open” to see its contents; if they both have full Windows folders (like Windows, Program Files, Users, etc., you likely have two real installations.

If you’re interested in removing an unused installation completely (not just a bootloader entry):

• First back up important data!
• Identify which partition holds the installation you want to remove.
• Format that partition using Disk Management.
• Use msconfig or bcdedit to remove the leftover boot entry if needed.
