Though it certainly makes u work a bit harder but u can deal with MBR problem, even if u Install Linux first.Don't worry , if installation of windows overwrites lilo or grub linux boot loader.
just boot the system with linux bootable cd
then choose following option
boot: linux rescue
it will detect existance of linux and ask you to execute
after mounting you can acces all the directories of linux
to reload grub
# cd /boot/grub
to reload lilo
it will reinstall grub or lilo in MBR
simple , isn't it
Is any moderator reading this, if yeah then do tell if anythings wrong in it.Though im confident it is not.
