i saw your question.now the problem is if you are having an old bios because some bios,the old ones,does not allow booting from a partition that is beyond the 1024 cylinder.now the question is about the age or rather the bios version.i am sorry pal but i have no answers right now.anyway if you can get hold of a third party boot manager then there will be no problem in booting either of the OS.
i could also give you a suggestion which may or may not work out.
try it out and let me know if it works.
install linux on the first primary partition and make a boot disk for it.next install windows.after that boot into linux and edit the lilo.conf file in the /etc directory and make an entry for windows aswell.after that run lilo.may be this might work..
i have never tried this as i own a new machine which does not have problem booting from beyond 1024 cylinder.once again i have not tried it so spare my ass if i am wrong..
