Re: is there an Boot Sector or Partition Table on usb flash disk?

thanks for your answer ,
i have make sure that there are boot sector on the usb flash disk, and i
used dd if=/dev/sda bs=512 count=1 to read the boot sector

What do you mean by "boot sector"? A boot sector is present on every
partition of your disk. But the very first sector of the disk contains the
master boot record (MBR), which includes the partition table and the code to
boot the active partition (i.e. it executes the code of the partition's boot
sector).

So I don't know what you want to do with your nice sector image, even if
it's the most important sector of your disk.
