Formatting and creating a bootable flash drive in Linux?

Question

linux

Good day!
When formatting a flash drive in Linux/Ubuntu, the drive does not work correctly. Inability to browse the file system "errors fly out".
Further, after formatting with third-party software in fat32 and further creating a bootable USB flash drive from the terminal, problems also occur.
Hangs on starting booting. With the help of third-party software everything works fine.
Used the following commands:
sudo dd if=path to .iso of=/dev/sdb - write image
umount - before formatting
sudo mkfs.vfat -n 'Ubuntu' -I /dev/sdb - format to fat32 Thanks in
advance!

Answer 2

first dd and then formatting? Or vice versa?
in general, these actions together are meaningless. dd - copies an image from a file to a device. The file system does not give a damn, in fact, it immediately creates it, along with the contents.
Well, if we first merge the image, then format it, then in fact we erase all our work, leaving the flash drive clean ... Well, if we first format and then merge the image, then formatting is simply meaningless.
In general - one dd should be enough for you
