I've some question regarding bootable pendrive and ISO.

  • How to make a normal ISOimage(just containing folders) or USB boot-able ,if one wants to do it manually, how to do it ?
  • what is difference in BOOTSECTOR of normal pendrive and a bootable pendrive ?
  • What if I have UBUNTU ISO(not a LIVE-CD) with all it's content, how to make it bootable?

Any help or link will work too ......
