When Windows is reinstalled it will overwrite the masterbootrecord of your harddrive. That disables the bootloader. You will have to boot with a Live-CD and do a chroot into your Linux-partition and reinstall the bootloader.

Most install CDs allow you to use the root=/dev/sdan option when booting to automatically chroot and log into the linux system installed on /dev/sdan. Say you installed linux on /dev/sda3, you'd boot from the install CD and type linux root=/dev/sda3 at the boot: prompt. You should be able to log into your linux system and then use the appropriate command for whatever bootloader you use. (LILO is just lilo or lilo -M /dev/sda to reinstall. I'm not certain what any other bootloaders use, but it should be in the man pages for the specific bootloader.)
