I have discovered that some important Windows system files are not where they should be, and I'd like to know if I can move them.

My system runs (I thought) from my D: drive, which has the usual \WINDOWS directory. However, ntldr resides on my C: drive, which otherwise contains only data (photos, music, etc). msdos.sys and boot.ini reside on C: too.

This is a big surprise to me, and not a welcome one. I suppose it has to do with the fact that I installed Windows (some time ago now) to D: while I had my C: drive attached; and maybe Windows can't cope with that unconventional set-up.

Is there anything that I can do about this, short of re-installing Windows? I am praying that a re-installation of Windows is not the only solution; it would take me days to return my computer to normal operating status.

Is this something that is bothering you right now? If the OS is working ok, why not just leave the files there? I can't really see why you would need to reinstall the OS now. –  alex Sep 26 '09 at 5:22
    
It bothers me for two reasons: a) If I ever remove the drive currently assigned C:, my computer won't boot; and b) I cannot perform system encryption with TrueCrypt –  user10604 Sep 26 '09 at 7:02
    
Because of (b) you'd better reinstall. While at it you can also consider using Hidden System feature. –  Bender Sep 26 '09 at 7:12

A reinstall is not the only solution, but it would be the fastest and cause you the least problems. Windows is used to having the C: drive as the main partition holding the Operating System files. Some applications likely have this hardcoded, hence the appearance of files like ntldr in the root of C: when its running from D:. A big problem you will run into is that all of your software is now installed and configured to use D:. If you move everything over, there will likely be a ton of programs that will break since they cannot find configuration folders and files. If you want to save your data, I suggest using the Files & Settings transfer Wizard or Windows Easy Transfer (depending on your current version of Windows). Make backups before doing anything drastic though.

Aaargh! I was afraid you'd say that. Thanks for the tough love, though. –  user10604 Sep 26 '09 at 7:04

I suggest that you do nothing about it. There is nothing wrong with the files being in the C:\ . And I don't think that the values are hard-coded. It just may be that C:\ is physically the first partition of you Master Hard-drive & hence Windows is dumping the boot files on it.

See my new comment on the question (above). The C: and D: drives are separate physical drives. –  user10604 Sep 26 '09 at 7:03

I have a wild idea, which would require good imaging backup of D because it can potentially be destroyed:

  1. Repartition your disk D to make it a bit smaller and move it towards the end of the disk.
  2. Create a new partition at the beginning of D. This will be your new C disk.
  3. Format and transfer all system files to the new partition,
  4. Take out the old C drive and replace it by the D drive. Keep the old C aside.
  5. Boot from this drive. Or use the Windows restore disk to repair the installation on D if required.
  6. Reboot with the old C drive in the drive bay where the old D drive used to be and call it E.
  7. Erase the system files from E.

I take no responsibility whatsoever and do not guarantee that this will work nor how much time you will spend trying to make it work.

this is is perfectly normal, while you can install the operating system on any drive you like, windows will always install certain boot files (such as NTLDR, BOOT.INI) on c:\

you want to remove the original C:\ drive? no problem:

I'm tempted, but scared by this statement from the first article: "Do not use the procedure that is described in this article to change a drive on a computer where the drive letter has not changed. If you do so, you may not be able to start your operating system." –  user10604 Sep 26 '09 at 12:51
    
of course you may not to mess around with your system without a complete backup. then there is no reason to be scared. worst case scenario would be a re-installation (which may not be such a bad idea after all :) –  Molly7244 Sep 26 '09 at 13:13
