Hello Everyone.. I have a few things in my mind if which i wanna know can be done. 1- I have an 8 gb sandisk usb pen drive formatted in FAT32. 2- I have my windows xp in iso format 3- I have Hiren's boot cd. 4- I have portable virtualbox and a windows xp image for that. With these I basicly want to be able to boot my computer from that drive. But I want to be able use all of them at the same time. I mean that I want to get a menu like that: 1- Run windowsxp.iso 2- Run Hiren's boot cd.iso 3- Run windows xp with virtualbox Is there anyway to do that? Ps: Hiren has smthg here about booting his cd from a pen drive which did not work for me. I had a file missing error (http://www.hiren.info/pages/bootcd-on-usb-disk)
