Question :-
Last week when I try to start from my D Drive I change boot serial as D first on BIOS.

Later, when I start my Machine my previous C drive automatically changed to D drive and D to C Drive, Now I want to reverese it back, is ther any easy way to do so ?


Answer :-
It is better to perform full backup first.

Then follow these steps...............

- Log on as an Administrator.
- Go to start, run
- type Regedt32.exe
- Click OK
- Go to HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
- Highlight MountedDevices.
- click the right mouse, click Permissions.
- Check to make sure Administrators have full control.
- Quit Regedt32.exe ( you can simply close it)

- Go to run
- type Regedit.exe.
- Click OK
- Go to HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
- Find the drive letter you want to change to (new). Look for "\DosDevices\C:".
- Right-click \DosDevices\C:, and then click Rename.

- Rename it to an unused drive letter "\DosDevices\Z:". (This will free up drive letter C: to be used later.)
- Find the drive letter you want changed. Look for "\DosDevices\D:".
- Right-click \DosDevices\D:, and then click Rename.
- Rename it to the appropriate (new) drive letter "\DosDevices\C:".
- Click the value for \DosDevices\Z:, click Rename, and then name it back to "\DosDevices\D:".
- Quit Regedit.exe

Again run Regedt32.exe
- Change the permissions back to the previous setting for Administrators (this should probably be Read Only).
- Restart the computer.

If you can't click the right mouse after highlighting MountedDevices

Click on Security on the toolbar
then select permission

and follow rest of the steps.

Bharat ji
Yes you can.
It is always better to have full backup. just incase.
Playing with the registry is not recommended.

And It is not recommended to change the drive letter of system partition (that contains boot files), unless and until it is really necessary.

If you look at the question of this topic. In this case the contain of boot.ini file has to be changed too so if anyone does not know about boot.ini file then it is not recommended to follow this procedure. It will be better to leave the way it is. wink.gif
