you can add to XP /2003 menu in Boot.ini along these lines :
=============================
I downloaded Grub4DOS from
http://linux.softpedia.com/get/System/Boot/GRUB-for-DOS-3507.shtmlthen unziped it
it had fat12grldr.img so using winimage i made a bootable floppy.
and booted from that ok.
then I copied the GRldr and MENU.lst from th floppy to the root of my
IDE HDD C: drive
and then opened the Boot.ini which lives in the root of C:
and added (appended)this line to it
C:\GRLDR="start GRUB"
then saved it.
and rebooted it .
it went straight to XP menu and had the line "start Grub" on the menu
so using the down arrow key I navigated quickly to it and pressed enter on key board .
the GRUB4DOS menu came up.
Cool REAL cool!!!
quickly pressed ESC escape key to stop GRUB count down.
then went to command line and pressed enter.
at grub prompt I typed
root (
and then pressed TAB key
it indicated the floppy(fd0) the HDD(hd0) and rd (assumed it as ram disk
