How to make bootable USB drive?

Get a USB DVD drive (recordable). They aren't expensive and you'll probably find it very useful for other tasks, like when you need to install something or want to listen to a CD or watch a DVD. Also often PC's like netbooks don't come with installation or recovery CD's, but they usually have a recovery partition and have a utility installed with which you can make those CD's, which is the first thing that you should do, and with such an external drive you could make these CD's/DVD's.

ok , finally here u go.....

its long process to make ur usb drive to bootable,

For the following guide you will need the following

" Original Windows XP-sp2 CD ( I used windows Xp install disc with Service pack 2... i believe service pack 1 will work as well)
" USB hard drive or USB-Flash (any size from 256k up to 2G)
" Barts PE Builder
" PeToUSB utility

Note: Barts PE Builder has an install utility that will install and allow you to create shortcuts on desktop

The PeToUSB utility is in a zip format - you need to extract the files and run the PeToUSB application directly from the directory you unzipped them to.

1 Insert your windows XP-sp2 CD (if the auto-run feature pops up just close it )

2 Run the PE Builder program you downloaded earlier
The program will search your PC for your windows CD or windows installation files

A. Ensure that "Create ISO image: is selected
(the default name will show up as pebuilder.iso and I am leaving it like that for this tutorial)

B. Click on [Build] (the first time you do this it will need your permission to create the output directory)

C. Read and understand the Windows License agreement that pops up
and then click [I agree]

The PE Builder will then build its file structure for you.

This will take some time based on your hardware it will be different for everyone.
in my case it took approx. 2 minutes to finish.

3. Insert your USB flash drive or key into an available USB port

4. Run the PE2USB program you downloaded earlier

A. In the ---Destination drive area--- check to make sure the correct usb device you want to write to is selected.

B. In the ---Format Options--- area :
Put a check mark in Enable Disk Format
Put a check mark in Enable LBA (FAT 16X)
Type a Name in the Drive Label Section

C. Click [Start]
D. A popup window will appear and then Click [Yes]
F. Another popup window will confirming you are erasing your USB drive Click [Yes]

This will take some time based on your hardware it will be different for everyone.
in my case it took approx. 3 minutes to finish.

G. Another popup window will appear saying completed successfully! [Click [Ok]

H. PeToUSB should still be open... In the ---Destination drive area--- check to make sure the correct usb device you want to write to is still selected.


I. click on {Tools} then Click on {Display Drive Info...}
Look at the partition table midway down the popup window and check partition 1 it should read something like :

Partition Table
No Boot Type StartCHS etc.
1 0x80 etc.
2 0x00 etc.
3 0x00 etc.
4 0x00 etc.

we just need to look at the first one it should read 0x80 below the Boot column if it says 0x80 then it should boot correctly.

5. once it is complete close PeToUSB and try booting the Flash Drive on your PC or Laptop (assuming your bios is already setup to allow you to boot from USB)

Thats it if all worked well you should be done
