Changed my Drive Letter

Microsoft Windows xp media center editio...

Specs: Windows XP
So I was messing around this evening... Remember I did say messing around... and I changed my Operating System Drive (which was D:) to C: using Regedit. I did this because I cannot get Microsoft Security Essentials to install... kept getting a "The Microsoft Security Essentials Installer can't find the Necessary files to complete the installation...." So I thought maybe my drive letter was an issue.

Went to Restart the PC and it will show the XP startup screen, then go the the XP Blue logon screen... there it will stay, showing a small Windows XP Logo in the center of the screen, but no User Logon options will show up.

How do I change the letters back. Is there a way through Dos? or something as simple as changing the cables inside?

I am running XP Media Center

Have you tried booting into Safe Mode and reverting the changes?

So far Booting to Safe Mode gives me the same results as booting normally... just a bit bigger of a Windows XP logo. I have also tried Last Known Configurations that worked

Changing the cables isn't going to help one little bit.

The only thing you can do is attempt a repair install, That depends on the installation programme recognising the existing installation on drive D: and not thinking it is on drive C:

If that fails then it is a complete reinstall in the only answer. You may need some recovery software to get any files you need of the disk before you reinstall.

Next time f you need to change drive letters, use the Disk Management function. In the case it would have flatly refused to let you do it because of the problems it can cause.

What commands should I be using in the recovery console to correct this

Sorry but there are no commands in recovery console to undo your registry edit.

The recommened repair install requires a working cdrom drive.

This is your best path to repair the OS and still retain your data and programs.

There is no option to do a remote edit of the registry since the OS doesn't come up. Except for replacing the files from backups... which of course we don't have available, it comes back to your best option being a repair install.

Best you fix that cdrom drive :)
