When you say "run Windows operating system" I assume you are trying to read data from your windows partition. You can't run windows software in Linux -- at least not without something the the WINE emulator, or a third party tool like win4lin or vmware.
Assuming you are talking about mounting your windows partition, you didn't say what version of windows you are running or what filesystem your windows partition is (fat32 vs. ntfs). Linux can read/write to fat32 natively. Linux can read ntfs with an add-on, but ntfs write support is very flakey and not supported.
Here is a howto on how to add ntfs read support to FC2:
Either way, you'll need to create a directory in your /mnt such as /mnt/windows and then edit your fstab to mount the windows partition at bootup. There are lots of posts on how to do this.
As for your mouse, you didn't say if its was a ps/2 or usb mouse, or what type of mouse. Also, post the contents of your fstab file. The answer will probaby be to edit that. I assume you already tried to reconfigure the mouse with the gui mouse configuration tool?
