Hello guise, I have an .iso file that is Backtrack v4, and I do not have any cds/dvds lying around so I figured, "Ah what the hell." So I created a new partition based off of the main boot partition C: drive, and installed the .iso file. Thing is, I'm not very savvy as far as disk management/partitioning goes, and perhaps what I am doing is pure stupidity, but eh. My problem is, I have the partition (logical,drive t)
But its not the main boot partition, and I would love to be able to change from windows seven to backtrack and back. Help appreciated

Ok; I'm a tech, just not a Linux one. So best I can do is do a little googling and point you to where the answers will most likely be :-)

Live install, dual boot from grub
This is another method to create a live install of BackTrack 3 on your HD. The need for this was that an install of BT was required for a machine with only 4gb of disk space and that it also needed to be dual booted with another linux distro from grub. This is a very simple live install with no persistancy. it has been done on an eeepc.
1. Create partition for backtrack (750mb) 2. Copy CONTENTS of iso to said partition 3. Edit your grub bootloader 4. Boot
So here goes...
1. create a partition for the BT iso (750mb will do). 2. grab a copy of the iso from download section. 2. mount the iso somewhere i.e.
mount -t iso9660 -o loop,ro /path/to/theiso.iso /mnt/iso
3. mount the partition you want BT upon. i.e.
mount /dev/hdX /mnt/bt
replacing /dev/hdX with the name of the disk and partition you are installing to (i.e. hda2 (first hdd, second partition)
4. copy the contents of the iso to the new partition. i.e.
cp -r /mnt/iso /mnt/bt
5. edit grub /boot/grub/menu.lst
Add this:
title BackTrack
root (hd0,1)
kernel /boot/vmlinuz max_loop=255 initrd=initrd.gz init=linuxrc load_ramdisk=1
prompt_ramdisk=0 ramdisk_size=6666 root=/dev/ram0 rw
initrd /boot/initrd.gz
boot
Obviously replacing root hd(0,1) with the partition number the kernel is on and changing the path of 'boot/vmlinuz' to point to the kernel.
6. If you want a directory that will save your changes and merge them with the live install to create the illusion of a 'real' install (the best way if you ask me) then:
a) Create another partition formated to ext2/3
b) create a directory on this partition called 'changes'
c) add to grub conf (above) at the end of the kernel line:changes=/dev/sdx rw
Where sdx is the name of the disk/partition you wish to use.

Soo..About this grub loader..anyway to install this with windows 7 without a bootup disk?

That's going to depend on everything from experience to preference. I recently spent many hours trying to find the easiest way to install an OS on a USB stick.

I imagine that getting a Linux OS on a USB stick might be a useful tool which will give you a lot of options that you don't have because you don't have a CD drive. You will most likely (like myself) have to spend a few hours trying different options until you get the one that works right for you.

You can save some time because I'm going to point you to some resources that I didn't have in the beginning of all of my work.

Universal USB Installer

Like I'm getting at above, the arguments for which Linux distro to put on a USB drive are debatable. I think from various perspective that the arguments are strongest for Puppy, Ubuntu, and Knoppix; not necessarily in that order.

Once you get a bootable OS on a USB drive then you have more options available to you like adding a grub boot loader to your system.

So much more I could say here but I'll let your questions guide what advice I might give you next.

Always back up your machine to an external disk before trying any serious techy tricks like creating dual boot systems, partitioning your drive, etc :-)
