Hello I am trying to make an USB flash bootable and I wonder which software can help me with this?
I am very new to linux but I have tried to use the 'disks'-> restore disk image
and I also tried dd
sudo dd if=inputfile.iso of=/dev/disk bs=4m

so long so good. Thing is when I am restarting the computer, the boot manager dont see the USB. I have enabled USB-booting in the BIOS and I have changed the booting order.

thing is I can obv see the usb in Linux so i wonder if the bootable usb fails or if there is some other (none) linux problem?

You may have to turn off the secure boot for the particular version of Linux you are trying to boot from on the USB. Do you have VirtualBox or VMware to test your boot media? I usually have a virtual box for troubleshoot such issues. Another option is to attempt to create your boot media with PowerISO on a windows box.

i had the secure boot disabled in BIOS.

qemu couldnt either find the USB on startup. The ISO did however obv work here so it has to be something going wrong when i am making it bootable?

G'day @potatis and welcome to linux.org :) . G'day @Drizzit89

...and I also tried dd
sudo dd if=inputfile.iso of=/dev/disk bs=4m
Are you running another version of Linux, to use dd?

...for the particular version of Linux you are trying to boot from on the USB.
So tell us how your computer is set up in terms of Operating Systems, and what is the Linux you are trying to install or boot to.

BTW if you used Linux to run the dd command, you can access the command used using your up direction arrow in Terminal.

Yes I use Debian for dd

I just want to be able to create bootable USBs from here.
I have actually tried with both win and linux iso but none work

Thanks, that's why I need the exact command you typed in to build the stick. :)

On the face of it, that looks OK.

When dd is finished, have you popped out the stick, reinserted it and used File Manager to establish that there are contents on the stick?

I have to go on an unscheduled road trip and will be away for 8 hours.
