I'm trying to create a bootable USB for Kali Linux. When I plug my USB in it recognises it in disks, but I'm not able to format or anything. Here is a picture:

EDIT: I am not having trouble with uploading the ISO file and making the USB a bootable USB, I am having trouble because Ubuntu won't properly recognise the USB drive.

This is what I get when I launch startup disk creator Image here.

  • I have got the latest version of ubuntu so i believe 19.04 and I tried used disks to create it – Barty 200YT Nov 4 '19 at 19:25

    Disks does not create bootable USB. It helps you manage internal and external disks and partitions. You need "Startup Disk Creator" or another app like mkusb or BalenaEtcher. – user68186 Nov 4 '19 at 19:30
  • I used the restore disk image and selected the iso file – Barty 200YT Nov 4 '19 at 19:32

    @Barty200YT Thanks--sorry about the iso tag, which may not apply here. It looks to me like the USB drive just doesn't have any partitions on it (or doesn't have a usable partition table), but if that's not the case or you don't think it explains what you're seeing, then I recommend running dmesg before and after plugging it in; the lines that are new after you plugged it in may make useful additions to your question. – Eliah Kagan Nov 4 '19 at 20:09

Disks has a way to do it, with its --restore-disk-image option; once you have created a LiveUSB ISO image, you can replay it onto a USB Flash Drive to create a LiveUSB. From its GUI, pick the USB drive on the left panel. Then choose Restore Disk Image... from the drop-down menu. Many thanks to user68186 for that development!

The preferred method per Ubuntu Tutorials https://tutorials.ubuntu.com/tutorial/tutorial-create-a-usb-stick-on-ubuntu#0 has explicit step by step instructions using Startup Disk Creator to create a LiveUSB from an ISO file. In step 4, instead of selecting the Ubuntu ISO file, use your other ISO file.

If your USB flash drive is rejected by Startup Disk Creator, then it is failing or has a bad connection. Make sure to plug the flash drive into a socket on the PC, not through a cable or hub.

If it still fails, follow the instructions in How to create a bootable Ubuntu USB flash drive from terminal? or use a different USB drive.

  • My usb isn't connected through a hub and has a good connection and i don't have any other usb sticks with enough memory – Barty 200YT Nov 4 '19 at 19:57
  • It's not because it worked yesterday and i used it to install ubuntu on my computer – Barty 200YT Nov 4 '19 at 19:59

    The --restore-disk-image option of gnome-disks allows creation of Live USB from ISO files. So based on the man page you linked in the answer, you can create a Live USB with Disks. I just tried it. It does create a Live (bootable) USB. – user68186 Nov 4 '19 at 22:04

    I didn't use the command line option, though I see that it is available based on the man page. I used the Disks GUI. Selected the USB drive on the left panel. Then chose Restore Disk Image... from the drop-down ≡ menu. – user68186 Nov 4 '19 at 22:28
