I searched google for xmnt2002.exe and it looks like this happens a lot when you foobar the partitions during resizing. Slackware would not dare touch a windows drive unless you make it. You will probably need to re-install lilo on the MBR, hopefully you will not need to reinstall windows, but if you do, make sure to install a real boot loader (such as lilo or grub) on top of it.
also, posting more detailed information will help you get better answers.
