Thank you for the detailed answers! :-)
Now I already have a *.img file , it's came from " dd if=/dev/sdc 0f=*.img" in
Ubuntu , and sdc is a usb flash . I want to write the *.img to the same usb
flash in freedos to make a linux bootalbe usb flash , do I have a simple way?
I tried the "rawrite" " diskcopy" , they are all for floppy disks.
Hoping for your answer, thanks so much!
