    #fdisk -l
3. Open gparted on the USB drive device
    #gparted /dev/sdc
4. In gparted delete all partitions then do the following:
    a. Create a new partition table, select type: 'msdos'
    b. Create an NTFS partition
    c. Through "Manage flags" option, check 'boot'
    d. Exit from gparted
5. Copy all the contents of /mnt to the root of the newly prepared USB drive
6. Unmount the newly prepared USB drive (which was mounted automatically by the Ubuntu file manager when inserted earlier)
