I want to convert a bin file to a bootable ISO.

I follow the instructions in this link,"How Can I Make a Bootable CD With ISOLINUX?" to create a ISO file.

I put my bin file in images folder, isolinux.bin and syslinux.cfg in isolinux, memdisk in kernel.

I burn the ISO file into USB and boot my computer from the USB. I use dd commend.

dd if=file.ISO of=/dev/sdb

It shows

FATAL: No bootable medium found! System halted.

I find someone said that the message means your ISO is not bootable. I don't know where is the problem. I pretty sure that my bin file is a bootable image.

Besides, I don't know is it helpful: I can open the USB in Ubuntu, but in Windows, it asks me format the USB.

    How did you "burn the ISO file into USB" (what commands did you use)? Please add this to your question as if you had included this detail originally. Do not write "Edit" or "Update". Do not reply here in a comment. Commented Nov 9, 2017 at 8:06

The ISO image you have created only boots if written to optical media (CD, DVD, or a Blu-Ray disc).

USB sticks boot differently. You need to add a boot record to your image file before writing it to the USB device.

See Isohybrid.
