WinXP와 젠투의 멀티부팅시에 설정을 어떻게 해야하나요?

Primary master HDD 전체에 윈XP를 사용하고 있는데요... Primary Slave HDD에 수세리눅스를 깔아서 쓰다가 젠투를 설치하고 있습니다. 수세는 grub설정을 알아서 해줬기 때문에 어려움이 없었는데 젠투의 경우는 어떻게 해줘야 하나요?

라이브시디에서 fdisk -l을 했을 때의 내용은 아래와 같습니다.

livecd ~ # fdisk -l

fstab에서의 설정은 아래와 같이 했구요

# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of storage
# efficiency).  It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# See the manpage fstab(5) for more information.
