Hi I am trying to use the defualt configuration file and got the same error.

Can you tell me what was the exact problem and how did u fix it.

My configuration file looks like as follows

#
# This is an example for a configuration file that can
# be passed to colinux-daemon in this manner:
#
# colinux-daemon @example.conf
#
# Note that you can still prepend or append configuration and
# boot parameters before and after '@', or you can use more
# that one '@ to load several settings one after another.
#
# colinux-daemon @example.conf @overrider.conf mem=32
#
# Full list of config params is listed in colinux-daemon.txt.

# The default kernel
kernel=vmlinux

# File contains the root file system.
# Download and extract preconfigured file from SF "Images for 2.6".
cobd0="c:\Program Files\coLinux\root_fs"

# Swap device, should be an empty file with 128..512MB.
#cobd1="c:\Program Files\coLinux\swap_device"

# Tell kernel the name of root device (mostly /dev/cobd0,
# /dev/cobd/0 on Gentoo)
# This parameter will be forward to Linux kernel.
root=/dev/cobd0

# Additional kernel parameters (ro = rootfs mount read only)
ro

# Initrd installs modules into the root file system.
# Need only on first boot.
initrd=initrd.gz

# Maximal memory for linux guest
#mem=64

# Slirp for internet connection (outgoing)
# Inside running coLinux configure eth0 with this static settings:
# ipaddress 10.0.2.15 broadcast 10.0.2.255 netmask 255.255.255.0
# gateway 10.0.2.2 nameserver 10.0.2.3
#eth0=slirp

# Tuntap as private network between guest and host on second linux device
#eth1=tuntap

# Setup for serial device
#ttys0=COM1,"BAUD=115200 PARITY=n DATA=8 STOP=1 dtr=on rts=on"

# Run an application on colinux start (Sample Xming, a Xserver)
#exec0=C:\Programs\Xming\Xming.exe,":0 -clipboard -multiwindow -ac"

You haven't edited it to show the fs and swap files:

Code:
cobd0="c:\Program Files\coLinux\root_fs"
and the swap:

Code:
cobd1="c:\Program Files\coLinux\swap_device"
Put the filesystem and swap details in and remove the hash marks.

When I tried coLinux recently I used the Debian-4.0r0-etch.ext3.1gb, and the swap_512Mb file.
