    A few months ago, a virus swept over my computer, and I ended up having to use a new operating system (The same Operating System (XP 2003 Home) but another copy) Now when I start up my computer, it asks me which operating system I want to use. I realize that the second one on the list is my old copy of Windows with all of my from before two months ago.
    Also, I just noticed that all of a sudden, I only have 5 GB of free space (69/74). I never had this problem before, and now I'm having trouble even running Disk Defragment (it says it wants 15% free space to run it).
    My questions are:
    How can I delete the old operating system? I can't very well get on to it. When I select that second Operating System, It takes me into safe mode. Then, when I try to log on, it immediately logs out and goes back to the log-in menu.

    Is the duplicate Operating System what is taking up so much space? I would say I probably have about 45 GB of programs/documents on the old one, and 25 GB on the new one. Do I have duplicate copies of the same programs (MS Office, Windows XP, etc...)

    If you could answer these questions, I would be your servant for life.

    Thanks,
    Jonathan

    Well, that's kind of obvious. But how do I get rid of it?

    How is your disk partitioned? In particular, are the two systems in different partitions?

    If you are having difficulty answering that: Control Panel - Administrative Tools - Computer Management - Disk Management. Your hard drive is probably identified as "Disk 0." What does it look like, left to right. I've attached mine for reference.

    It looks like it's only "Disk 0"

    OK, just one partition. Now you have to find the unwanted folders/files and delete them.

    Make sure in Control Panel - Folder Options - View tab - that you have 'Display the contents of system folders' and 'Show hidden files and folders' selected; and 'Hide extensions for known file types' and 'Hide protected operating system file' not selected.

    Now starting at the C: drive (open My Computer and double click on the C: drive) see what you have. You'll probably have two folders with "WINDOWS" in the name. The one that was modified today is the one you want to keep.

    Next stop is the Documents and Settings folder. Here you will probably find several "duplicate" folders. Once again, the newer one is the one you want to keep.

    Don't rush on these steps. You want to be sure you are deleting only stuff your really don't want.

    If there are any you cannot access you will probably need to Take Ownership.
