www.forum.remote-exploit.org

Or have a look at this thread.

look that man sorry i can't understand from him

i want to understand the part of creating the dual boot partitions
 
first how many partition ?

and how to create them with fdisk "commands"

and how many MB for each ?

details plz

cuz i think that the rest commands will be easy and after i umounted my hda3 dev that contain the ext3 when i tried to copy and mount it again it says the dev not found or not exist

This should help you if you are installing backtrack 3


Boot BackTrack live from CD, DVD or USB device
Unmount the existing partitions, the BackTrack Live has automatically mounted them.

Code:

umount /dev/hda1

Run QTParted to resize the NTFS partition
KDE menu > System > QTParted
Resize sda1 to make free space for BackTrack and save changes. Exit QTParted.

Create Linux partitions for BackTrack
Code:

fdisk /dev/hda

Create a primary partition number hda2 name it linux
Create a primary partition number hda3 1 GB in size, this will be swap

Format the new partitions
Code:

mkfs.ext3 /dev/hda2
mkswap /dev/hda3
swapon /dev/hda3

Mount the new partitions so you can install BackTrack on them
Code:

bt ~ # mkdir /mnt/backtrack
bt ~ # mount /dev/hda2 /mnt/backtrack/
bt ~ # mkdir /mnt/backtrack/boot/
bt ~ # mount /dev/hda2 /mnt/backtrack/boot/

Install BackTrack files
Code:

bt ~ # cp --preserve -R /{bin,dev,home,pentest,root,usr,etc,lib,opt,sbin,var} /mnt/backtrack/
bt ~ # mkdir /mnt/backtrack/{mnt,proc,sys,tmp}
bt ~ # mount --bind /dev/ /mnt/backtrack/dev/
bt ~ # mount -t proc proc /mnt/backtrack/proc/
bt ~ # cp /boot/vmlinuz /mnt/backtrack/boot/

And lilo file
Code:

bt ~ # chroot /mnt/backtrack/ /bin/bash
bt / # nano /etc/lilo.conf

In nano change your lilo to look like this, especially do not forget to add the last 4 lines.

boot = /dev/hda
prompt
timeout = 1200
default =Windows
#bitmap=/boot/splash.bmp
change-rules
reset
#vga = 769,771/773/792
vga = 769
image = /boot/vmlinuz
root = current
label = BackTrack3

#Boot Windows
other = /dev/hda1
label = Windows
table = hda

Excellent. Save that and then execute lilo
Code:

bt / # lilo -v

after that exit your chroot enviorment
and reboot and cross your fingers
Code:

bt / # exit
bt ~ #reboot

hey thanks really for this i already looked in offensive-security be4 but this is not the problem

question : how can i format the partition to make it new from the beginning cuz i unmounted it and created it from the beginning and the size N/A its and when im trying to do anything with it like  mkfs.ext3 /dev/hda2

it says that there's no hda2 for example although when i open qtparted i c it exist damn

i restarted my pc and i found it with size 2.7 GB again so wat i done useless i want to make no size to begin from the beginning but every time it return again should i delete it from partition magic or something ?

and why always when im doing this commands some commands not work

like cp /boot/vmlinuz /mnt/backtrack/boot/

no such file or directory

Most likely v2.

its CEH-BackTrack in the CEH v6 course dunno wat ver :S


and i do every command correct but my ext3 can't be formated when i did that with umount it first then format it i can't mount it again dunno wats going on
