yeah, windows will just stream roller through and nuke the MBR totally. but as you guess, just keep a bootdisk, boot back into linux and reinstall the bootloader. just run "lilo" as root if you're using lilo. you could also just take a copy of the mbr directly using dd and put it back on again after. there's a LinuxAnswer here that will give you the exact command for that.
