Type fdisk -l(and note which device is your USB Drive)

Type fdisk /dev/sdx (replecng x with your actual usb device)

Type d(to delete the existing partition)

Type n(to create a new partition)

Type p(for primation)

Type 1(to create the first partition)

Press Enter(to use the first cylinder)

Press Enter again(to use the default value as the last cylinder)

Type a(for active)

Type 1（to mark the first partition active「bootble」）

Type w(to write the changes and close fdisk)

II.Create a Fat 32 Filesystem on the USB Flash Drive：

Type umount /dev/sdx 1(to unmount the mounted partition)

Type mkfs.vfat -F 32 -n MULTIBOOT /dev/sdx 1(to format the partion as fat 32)

III.Install Groub 2 on the USB Flash Drive：

Type mkdir /media/MULTIBOOT(to create a directory for the mountpoint)

Type mount /dev/sdx 1 /media/MULTIBOOT(to mount the USB)
