Boot disks made of U disk can be roughly divided into two types: one is to draw a separate partition from the U disk space as the boot partition, which is invisible and hidden in the computer. The other is that there is no separate hidden boot partition, and there is only one boot partition in the whole U disk space.

For the second type of USB flash drive, the easiest way to restore it to ordinary USB flash drive is to format the USB flash drive.

For the first type of U disk startup disk, it needs to be operated by related tools and software to restore to ordinary U disk. Although it is easy to delete the hidden startup partition of the USB flash drive and restore all the space of the USB flash drive by using tools such as hard disk partition master, there are many operation steps, which is also dangerous for those who are not skilled in software operation, and may misoperate other computer hard disk partitions and cause data loss.
