Help! My hard drives have swapped drive letters on me!

[episcopus]

After recovering from a crash (which was probably due to overheating) I find that my two hard drives have swapped letters in Windows. I.e. the drive that used to be C is now D and vice versa.

That is a problem because since Windows is installed on D but now is on C, several programs will not work anymore, etc.

If I go to Disk Management, Windows tells me that I can't change the letter of the system / boot drive.

What could have caused this and how do I swap them back to the way it was before?

!!!!BEFORE doing this backup your system!!!!!!

-Go to Start > Run and type regedit and press Enter.
-Click your way down to HKEY_LOCAL_MACHINE > SYSTEM > MountedDevices
-Right click on \DOSDevices\D: and select delete.
-Right click on \DOSDevices\C: and select rename, and change C: to D: so it now looks like \DOSDevices\D:
-Reboot the system and you should now have a new hard drive with all of your existing settings as primary D.


BACK UP YOUR SYSTEM FIRST~!!

That totally did it! After running this I had to repair the windows installation once more (because it hung on boot) but after that, my OS was back to it's restored state. No deleted programs or settings.

Thanks!!!

Hey yo. How do you switch the assigned C / D partition letters if they were the originals on installing Windows Vista onto the hard drive?

Above info is only to be used if a switch has occured from original settings.
