===== Basic about boot disk =====
==== Master Boot Record ====
The MBR, the most important data structure on the disk: 
  * **is created when the disk is partitioned**. 
  * The MBR contains a small amount of executable code called the **master boot code**, the disk signature, and the **partition table for the disk**. At the end of the MBR is a 2-byte structure called a signature word or end of sector marker, which is always set to 0x55AA. A signature word also marks the end of an extended boot record (EBR) and the boot sector.

**Note**: There is **no MBR on a floppy disk**. The **first sector on a floppy disk is the boot sector**. Although every hard disk contains an MBR, **the master boot code is used only if the disk contains the active, primary partition**.
=== Master Boot Code ===
The master boot code performs the following activities:
  * Scans the partition table for **the active partition**.
  * Finds the starting sector of the active partition.
  * Loads a **copy of the boot sector from the active partition into memory**.
  * **Transfers control to the executable code in the boot sector**.
=== Partition Table ===
The partition table, a 64-byte data structure used to identify the **type and location of partitions** on a hard disk, conforms to a standard layout independent of the operating system. Each partition table entry is 16 bytes long, with a maximum of four entries. Each entry starts at a predetermined offset from the beginning of the sector, as follows:
  * Partition 1\ 0x01BE(446)
  * Partition 2\ 0x01CE(462)
  * Partition 3\ 0x01DE(478)
  * Partition 4\ 0x01EE(494)
Figure 1.1 shows the MBR, partition table, and boot sectors on a disk with four partitions. The definitions of the fields in the partition table and the extended partition tables are the same.

===== Create USB boot disk =====
==== Prepare tools ====
  * BootIce -> Make usb bootable(Write MBR, PBR)
  * Winsetupfromusb: http://www.winsetupfromusb.com/downloads/ -> generate menu.lst
  * rufus: http://rufus.akeo.ie/
==== Create boot disk ====

=== Using BootIce to write MBR(Master Boot Record) and PBR(Partition Boot Record) ===
  * MBR: Grub4dos
  * PBR: Grub4dos or BOOTMGR
  * BootIce read **menu.lst** to display bootable iso
=== Create Disk Boot Install for windows ===
Using WinSetupfromUsb to convert ISO windows(XP, windows7, Windows 8) for installing on USB
=== update menu.lst for menu boot ===
menu.lst<code>
title Active Boot Disk
find --set-root /Active_BootDisk.iso
map /Active_BootDisk.iso (hd32)
map --hook
chainloader (hd32)

title Windows XP/2000/2003 Setup
map --unmap=0:0xff
map --unhook && map --rehook
savedefault
ls /usbdrive.tag > nul || find --set-root --devices=hf /usbdrive.tag
configfile /winsetup.lst
</code>
==== Install WinXP ====
Check computer hard drive for SATA, If in BIOS enable SATA, we need to disable it
==== Create boot disk for iso ====
Using WinSetupfromUsb and function **Linux ISO/Other Grub4dos compatible ISO** to convert file ISO to USB for boot. Below are some ISOs created follow this method:
  * **hiren Boot ISO** -> **new GUI is Windows 10**
  * **Vsphere server ISO**
===== Create USB boot backtrack =====
==== Preparation ====
  * reference: http://www.remote-exploit.org/backtrack_docs.html
  * download: http://www.remote-exploit.org/backtrack_download.html
==== Make a BackTrack(v2 and v3) USB Stick ====
reference:http://wiki.remote-exploit.org/index.php/Howto:USB_Stick
=== step by step on linux ===
  - Step1: Open the backtrack.iso file:<code bash>
mount -o loop -t iso9660 backtrack.iso /mnt/iso
</code>
  - Step2: mount usb drive:<code bash>
mount /dev/sda1 /mnt/usbflash
</code>	
  - Step3: copy backtrack to usb flash<code bash>
cp -R /mnt/iso/boot /mnt/usbflash
cp -R /mnt/iso/BT /mnt/usbflash
</code>
  - Step1: Make the usb bootable<code bash>
cd /mnt/usbflash/boot
./bootinst.sh
</code>
=== step by step on windows ===
  - Step1: Open the backtrack.iso file<code dos>
use isobuster
</code>
  - Step2: copy /boot and /BT to usb drive J
  - Step3: Make the usb bootable<code dos>
cd J:\boot
bootinst.bat
</code>
=== Configure ===
  * Network(DHCP)<code bash>
ifconfig eth0 down
dhclient
</code>
  * DNS server<code bash>
edit /etc/resolv.conf
</code>
===== Experiences about installing =====
Install windows 7: Using windows 7 to format before install windows -> windows 7 will automatic create **system partition** to load windows 7 partition
