C drive problem?

hey guys my computer HD crashed a while ago and i sent it to be repaired and they installed a 320gb one BUT it was under H: not C: so i searched on the net and saw how to change H to C it said for me to:

1.Start Regedit.exe

2.Go to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\MountedDevic?br>
3.Find the drive letter you want to change to. Look for %26quot;\DosDevices\C:%26quot;.

4.Right-click \DosDevices\C:, and then click Rename.

5.Rename it to an unused drive letter %26quot;\DosDevices\Z:%26quot;.

6.Look for %26quot;\DosDevices\H:,Right-click \DosDevices\H:, and then click Rename.

7.Rename it to the appropriate drive letter %26quot;\DosDevices\C:%26quot;.

8.Click the value for \DosDevices\Z:, click Rename, and then name it back to %26quot;\DosDevices\H:%26quot;.

9.restart the computer



so i did and now when i start the computer it loads ok but then when it comes to the Welcome screen it just stays like that (u can seethe mouse n thats it ALT+CTRL +DEL dosnt work)

how can i fix it without sending it to the repairer.C drive problem?
Just change it back to H Drive.C drive problem?
You typically aren't allowed to change the drive letter of your system-drive because the system is locating your critical files on that drive. I'm surprised it didn't crash when you first changed it. :-)



Buy a cheap new drive, install it with your other drive, install Windows on it and use your original for storage. My system drive is F:\, I live with it.C drive problem?
You can NOT change the drive letter of the system drive. There are thousands of registry entries pointing to it, and most of them can not be changed in regedit as doing so would trash the system. This is exactly what you have now done. You need to re-install from scratch.C drive problem?
Well i have a similar problem to this... sort of. My C drive is actually I drive and my computer operates as normal with no issues whatsoever to do with the drive letter.... after all the drive letter is just a name for a location. If you can not open windows try to run windows in DOS. run the Regedit.exe and see if you can undo what you did... just be happy with the new drive letter... on the plus side hackers will look for Cdrive and find nothing if you stick with H drive :)
