You can Identify your device with the help of your USB’s Size. Here my pendrive is memory of 4.GB note that device path for mine it is /dev/sdb. Unmount your device before proceeding this you done it by the following command.
root@bala-desktop:~# umount /media/KRISH/
2. Syntax for the command mkfs.ext4 -n “<label>” -I <device_path>
Type the following command to format as Ext4:
root@bala-desktop:~# mkfs.ext4 -n "Tux" -I /dev/sdb
Type the following command to format as fat32:
root@bala-desktop:~# mkfs.vfat -n "Tux" -I /dev/sdb

I wonder how to make an USB with 2 partitions with 2 type of file system: ext4 and NTFS?
ext4: a bootable Ubuntu
NTFS: data
I have this one and it works good in my Ubuntu, but it can not work with Windows.
How can I figure it?
