works for me x_X

1. Go to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
2. Find the drive letter you want to change to (new). Look for "\DosDevices\C:".
3. Rename it to an unused drive letter "\DosDevices\Z:".
This frees up drive letter C.
4. Find the drive letter you want changed. Look for "\DosDevices\D:".
5. Rename it to the appropriate (new) drive letter "\DosDevices\C:".
6. Click the value for \DosDevices\Z:, click Rename, and then name it back to "\DosDevices\D:".

But, yes, you are pretty much screwed since absolutely everything on that drive from programs to registry settings points to G; as the drive they are operating from. That's 100's, possibly 1000's, of settings. Try a repair installation. That may or may not work for repairing the majority of errors. It may get you booted up, but there is little chance that your programs will run correctly unless the drive letter is restored.

The other option is to remotely edit the registry to restore it to the way it was. You can do that with RegeditPE within the UBCD4Win.

No, the link doesn't work. You are just copying it and not copying the shortcut. Please post the whole thing. Click on your own link above to see what I mean.

You're not the first. Setup will use C: unless it is already used, in which case it chooses the next letter (including optical drives sometimes), but most of us would like C: for our main drive. And some programs even assume that C: is the main drive. Unfortunately, there are no shortcuts for changing that. There are directions floating around, but the process is more complicated than reinstalling would be.

The Regedit PE is amazing. It imports the registry from the machine as a subkey, lets you edit it, and then unloads it back to the drive.

It takes some work to make the UBCD, but you will probably find it useful for repairs for a lot of other things, too, and especially for file recovery from broken systems since it will allow you to send files over the network, transfer them to CD or DVD, or move them to another drive. And there are no permissions issues with it, either. You have access to everything that is not encrypted.
