For the future...... Don't fuck with stuff unless you know exactly what your doing.  This kind of poo poo (I did xyz and now something is stuffed) happens too often.

yammata, I had a look around I reckon this would be a good bet to get rid of the entry (you added) that's causing the trouble: http://forums.kustompcs.co.uk/showpost.p...ostcount=5

So you'll need a hard drive with XP installed, connect it to your current rig, boot into it, and use the regedit in there to load the Registry on the drive with the unbootable XP.. remove the entry and you're done.

All I get is a blinking cursor. No prompts, no menus, no safemode, no error message, nothing (cries for hours)

If the Windows boot screen doesn't show up, I don't think it's a registry issue (unless the entire registry is corrupt) - what you edited seems like a shell level entry, and that's loaded long after most of Windows is loaded.
Windows loads drivers and stuff during its loading screen, so something seriously is stuffed - I think something other than your registry edit is causing this...

The registry editor lets you choose where the registry is relative to the system directory. I need to know how to access edit HKEY_CLASSES_ROOT (or HKCR). This is where the keys I changed were. I need to know what to type in when it prompts for the directory. If I leave it blank it gives me access only to HKEY_LOCAL_MACHINE. Any ideas?

The Windows registry only really has two true root keys, HKEY_LOCAL_MACHINE and HKEY_USERS.
HKEY_CLASSES_ROOT = HKEY_LOCAL_MACHINE\SOFTWARE\Classes


Having a second install of Windows is indeed useful though.
