At first I wanted to make me into a bootable Linux flash LTS 16.04, After the installation process is finished I want to restore my flash as before. when I checked, it turned my flash partitioned for making bootable "startup disk creator".
when I want to delete the partition had made an error.
Error Formatting Volume: This partition cannot be modified because it contains a partition table; please reinitialize layout of the whole device. (udisks-error-quark, 11)
and when I want to delete partitions also occurred error:
Eror Deleting Volume: Error deleting partition /dev/sdb1:
Command-line `parted --script "/dev/sdb" "rm 1"' exited with non-zero exit status 1:
Warning: The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 512 bytes. (udisks-error-quark, 0)
What should I do?
