One from many
Dell Vostro 3700 - Windows 7/CentOS 5.4 dual boot
# This goes from zero to CentOS 5.4 and Windows 7.
# With maintaining all the original Dell data partitions and Windows, adding a
# partiton for CentOS and a 190 GB ntfs Data partition that can be shared by both
# Windows 7 and CentOS 4.5
# RESULTANT PARTITIONS:
# Dell Diagnostics - 40MB - /dev/sda1 - fat
# Dell Recovery - 15GB - /dev/sda2 - nfts
# Windows 7 - 145GB - /dev/sda3 - ntfs
# CentOS 4.5 - 145GB - /dev/sda4
# It would be possible to make these sizes different but due to the number of
# partitions already on the drive it makes it more complicated.
# Open you cardboard Dell packaging box and take out the laptop. Insert the
# the battery and plug in the power. There is nothing in the documentation
# relating to pre-charging the battery before use so one assumes that the
# batteries are pre-charged (otherwise the manufacturers would be shipping out
# lots of replacements)
# REQUIREMENTS:
#
# 1. Knoppix Live CD - http://www.knoppix.net/
# Any version will do, version used here, KNOPPIX_V6.2.1CD-2010-01-31-EN.iso
#
# 2. CentOS 5.4 .isos available from your nearest mirror
# http://sunsite.rediris.es/mirror/CentOS/5.4/isos/i386/
# It would be possible to use the netinstall iso as well I am sure, however
# my laptop is run under version control, so I needed the actual source
# installs, netinstall versions change over time with yum.
#
# 3. A Dell Vostro 3700 laptop with an i3 core. I would imagine that much of
# this build may work for the i5 and i7 cores as well.
########################
# CORRECT SYSTEM CLOCK
########################
# On my system the sytem clock was incorrect from the first power on
# so first thing we do is ensure the system clock is correct. Mine was set to
# CDT (Dell Austin Texas?)
# Turn on the laptop and immediately press F2 repeated to get you into the Setup
# it is quick so if you miss it power down immediately and do it again, even if
# the "Starting Windows" appears on screen, just hold to power button in and try
# again.
# Set your time if required and should you wish to access any of the Main,
# Advanced, Security or Boot menus, use Shift+cursor (cursor being left, right,
# up and down arrow keys).
# And use the Shift+cursor for navigating other options as well .. maybe F1
# should say something about that, if NumLock is on by default which it is in
# Setup.
# Open DVD tray and insert Knoppix Live CD and close.
# Save any settings changes and reset.
###################
# BOOT KNOPPIX
###################
# PLEASE NOTE THE VERSION OF KNOPPIX USED HERE CANNOT RUN the default X graphical
# interface on the Vostro so we must enter it using failsfe debug
# With the Knoppix Live CD at the ready, turn on the laptop and immediately go
# into the Boot Option by pressing the "F12" key.
# Select the DVD/CD
# At the Knoppix boot: prompt use the following boot parameters:
# boot: failsafe debug -b 3
# Using this boot command will cause Knoppix to pause at various stages in the
# boot process. Just type 'exit' at each shell or Ctrl+d as prompted to move on
# to the next stage. You will know that you are at the final stage when typing
# 'exit' does not do anything just reports "logout" and the shell prompt is:
# root@Microknoppix:/# _
# To run failsafe X type:
init 5
# Now we want to record the original disk partition information before changing
# it. You never know...
# Select "Start Menu" > Accessories > Root Terminal
############
# INFO ONLY
# Now we are going to decrease the size of the Windows partition
# The Vostro 3700 has 3 partitions on the disk:
# Filesystem Size Used
# /dev/sda1 40M 9.0M
# /dev/sda2 15G 3.8G
# /dev/sda3 284G 269G
# /dev/sda4 0 0 System is labelled empty
# These contain the following:
# /dev/sda1 - Dell Diagnostics
# /dev/sda2 - Dell recovery partition (fresh Win 7 copy)
# /dev/sda3 - Main working Windows 7 partition
############
# Now we get the a list of the disk partition values.
# We also save this to a new directory on the main Windows drive so that there
# are records of the original values should you ever need them by issuing the
# following commands:
mount /dev/sda3
# If you have a problem here check your /etc/fstab to ensure the partitions are
# mapped to /dev/sdaX to do that issue the following command "cat /etc/fstab"
# Now we have mounted the partitions the values...
# Making the log directory so we can always see what was what.
mkdir -p /mnt/sda3/dell_vostro_3700
sfdisk -l /dev/sda | tee /mnt/sda3/dell_vostro_3700/original.drive.partition.details.`date +%Y%m%d%H%M%S`.log
umount /dev/sda3
# The output should be similar to:
# Disk /dev/sda 38913 cylinders, 255 heads..... blah blah
# ...
# Device Boot Start End #cyls #blocks Id System
#/dev/sda1 0+ 4 5- 40131 de Dell Utility
#/dev/sda2 5+ 1917- 1913- 15360000 7 HPFS/NTFS
#/dev/sda3 1917+ 38913- 36996- 297169240 7 HPFS/NTFS
#/dev/sda4 0 0 0 0 0 Empty
# Now we are going to resize
# Start Menu > Preferences > GParted
# Right click on /dev/sda3 on the list > Resize/Move and set the new size value
# to what you want it to be e.g 290204 MB to 145000 MB
# Now click in the Free space following box and it will automatically refresh
# with a new value, leave this value (.e.g 145203) leave Round to cylinders
# ticked.
# Click Resize/Move
# It is now committed as a operation, in the main Gparted windows click on the
# top window menu click Edit > Apply All Operations
# "Are you sure you want to apply ..." Click Apply (or yes) not close
# At the Completed Opeartions window (check all went well) and click Close.
# Start > Menu > Logout > Shutdown.

# ATTENTION: This driver module is NOT persistent across kernel upgrades

# have to do this over again). And again, this is why you placed the archive
# contents in /usr/local/src/hybrid-wl and changed the ownership of the
# directory and it's contents.
