Dear All I have made bootable-USB by using boot loader Grub4dos and now I'm seeking to do backup copy from USB, I attempted to get a program to do that and I have found ISO greator program to do ISO image from any source media but I have failed to determine the image file from USB stick. So, Is there a program (method) to make ISO image from bootable USB? and aslo Is there a program (method) to draw out boot files from bootable USB as we do with CD/DVD by using MagicISO or UltraISo programs? By the way, I have found program specially to do backup copy from USB stick is called USB image tool but file extension is .img, I can't convert this .img to .iso to be changable by any suitable program. I'll be thankful for helping. Engr. Mohammed
