can I uninstall a previous windows installation with disk cleanup?

I have windows vista and I think this computer used to have windows 98 or something on it. A few months ago, I used the windows vista disks and installed that onto the system. Now whenever I go to disk cleanup, it's telling me that I have a previous installed version of windows and I'm afraid that deleting it will really mess up my computer. The file is so large though that it's probably slowing down my computer. I read some about this and saw that I should have a folder called windows.old but I can't seem to find it on the computer.

    Either you didn't do a clean install or the other OS is on another drive,if it's on another drive use disk management to format it and wipe it clean.Yes there should be a windows.old somewhere if it was on the same drive.It shouldn't slow the computer down cause I use vista/xp and 7 as a triple boot.If the computer is old it might not have enough memory or speed for vista.

    Long winded and probably not much help - good luck.

    edit: disk cleanup - no
