i am trying to install Ubuntu onto my bootable USB that make persistent data and did not alter my main OS.
i am running on a 32gb Sandisk drive. The ISO file and the device that i am trying to install are the same one.
i am already use rufus and ISO file onto my USB
in ubuntu system, i already umount the device
Right now i am try to install ubuntu on other device option
the problem is,
during installation, i did choose my USB drive and when i try to format it to "ext4 journaling file system" with mount point "/"
i am getting an error which is "the ext4 file system creation in partition #1 of SCSI3 (0,0,0) (sdb) failed"
