How to create a bootable disk?
 

i modified the thinclient OS PXES cfg file.NOw i want to create bootable disk of pxes.iso file so that i can mount in Virtual box and check whether it wirks properly.i first created a normal ISO using MAgic ISO.when i try to create a bootable disk using the same ISO it asks for "load boot information file".i dont know which file should i select.
All i want is to create bootable disk of the customized PXES OS and mount in virtual box and test it?
