i think you can install only one grub to boot the two system with editing menu.lst.
Do you mean that when i install Debian, I can skip "the boot loader installation" ?
The boot loader on Gentoo is installed on MBR. So if i want to install another boot loader on Debian, where can i install it on? Can the boot loader that is installed on none-MBR partiton can be automatically recognized when system boot up?ps: two grub is ok.
/ directory is not suitable to share. poor english, too.
