Can’t create bootable usb xp setup

Hi,
I have a laptop with no cd reader, and i need to reinstall xp (since i have a lot of viruses that i can’t get rid of). I downloaded windows xp sp3 setup (.iso) and i serched for tutorial of how to create a bootable usb for the setup. i found some methods, but they didn’t work (the computer could not boot the usb, it just restarted the computer over and over, or stuck on black screen). Do you know a method that really works? (i preffer one that dosen’t include cmd, but if there is no choice i can do it)
Please help,
Ofir.

1. Download Windows XP SP3 ISO http://www.google.com?t=4239529&highlight=
2. How to copy ISO to USB
First up, we need to prepare the flash drive.
–Download and unzip this file
http://www.~ Dead file host ~/?d=XV2WJEY3
which should contain 2 folders: 1 titled Bootsect, and the other USB_prep8.
–Navigate to the USB_prep8 folder and click on usb_prep8.cmd. This will bring up a Windows console window.
–Press any key to continue and a PeToUSB window will open.
–Make sure your flash drive is selected, and click start to format your flash drive.
–When the format is complete, click OK, but do not close the PeToUSB window or the Windows Console.
–Open a new console window by typing �cmd� into the run box in the Windows Start Menu.
–Find your Bootsect folder (if you�re not used to DOS commands, you can type �dir� to list directories and files, type �cd foldername� to navigate to a folder name � called foldername in this example, and if there�s a long folder name you can save time by typing the �cd� and just the first few letters and then hitting the Tab key to fill in the rest of the name).
–Once you�re in the Bootsect folder, type �bootsect.exe /nt52 g:� if �g� is the letter assigned to your flash drive. If it�s E, then change the letter to e. If it�s Z, make it z. Get it?
–When this is done, you should see a message letting you know that the bootcode was updated, and you can close this console window (but not the other console window).
–Close the PeToUSb Window, but make sure not to close the remaining console window yet
–You should now see a list of 8 options in the console.
–Select one and find the drive with your Windows installation disc.
–Select 2 and pick a random drive letter (but not one that�s already on your PC, since this will be a virtual drive used for copying your files).
–Select 3 and enter the drive letter for your USB flash drive.
–Select 4 and follow the rest of the on-screen directions and you should be all set.
–The process should take about 15-20 minutes. When it�s done, you should have a bootable USB stick that you can use to install Windows XP the same way you would if you had a CD/DVD drive.
