Dear all members,
I have installed WinXP in C drive, Win Server 2003 in D drive and Linux in E drive. But when i installed Linux on E drive, i got unable to load Win XP while Win Server 2003 is running smoothly. Can anybody tell me the main cause along solution.
Waiting for a precious reply from all of your side.
Thanks in advance!!!

What Linux distribution?
Does the Linux install run OK?When you installed Linux, did you install a bootloader (GRUB or LILO)? If so, please post the contents of the configuration file (for GRUB, this is probably /boot/grub/menu.lst)

Note that--when running in Linux--you will not see the Windows drive letters. If you have regular IDE, you will have /dev/hda1 (first partition on the first drive) and others depending on your setup. (e.g. do you have 3 drives, or three partitions on one drive?) If the Linux install is working, post the output of cat /etc/fstab

No, i have one hard disk having three partitions C,D and E on which WinXP,Win Server and Linux respectively are installed.
The contents of the file "boot/grub/menu.lst" are displayed below.

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,6)
# kernel /vmlinuz-version ro root=/dev/hda9
# initrd /initrd-version.img
#boot=/dev/hda
default=1
timeout=10
splashimage=(hd0,6)/grub/splash.xpm.gz
title Red Hat Linux (2.4.20-8)
root (hd0,6)
kernel /vmlinuz-2.4.20-8 ro root=LABEL=/ hdc=ide-scsi
initrd /initrd-2.4.20-8.img
title DOS
rootnoverify (hd0,0)
chainloader +1

Ok--Redhat Linux is on Partition #7 of the drive, and one of the Windows installs in on partition #1 (Grub counts from 0)
So the first thing you need is an entry for the other Windows install.

Please post the output of "cat /etc/fstab" so we can see the complete partitioning setup.

(I'm assuming that both things listed in the current menu.lst are booting OK)

Here is the output of "cat /etc/fstab"

LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hda8 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0

My mistake---I meant to say "fdisk -l" We are looking for a list of all your partitions
