After messing somethign up after running Windows Update and then Auslogics Registry Defrag on Vista Ultimate, I'm trying to fix the problem by running System Restore from the original (full) install disc. After I click "Repair your computer", I get the dialog in Figure 4 on http://www.bleepingcomputer.com/tutorials/tutorial142.html, just with no drives showing up in the list box. I can click the "Next >" button to proceed to Figure 5, but System Restore will cease to function, throwing an error message which says that I need to specify a volume to run an ofline restore or something of that sort. I originally installed Vista Ultimate to an eSATA drive with an older SATA drive that already stored XP. What is preventing me from selecting the Vista partition?
