I'm trying to create a live Ubuntu OS on a 512gb SSD (mSATA drive inserted into a USB-interface housing). I've tried to create the live USB using several software (Universal USB Installer; Unetbootin) and file formats (FAT32/NTFS).

However, whenever I try to boot up the PC with the USB SSD it always says "Missing Operating System". Live USB works fine when it is installed into a 16gb pen drive but I somehow can't get it to work on the USB SSD. I wonder if anyone knows what is the reason behind?

Details are as follows:

  • OS I have access to: Windows 10 (on another PC)
  • OS to be installed: Ubuntu 18.04.3
  • Motherboard: Gigabyte Z68P-DS3
  • There doesn't seem to be anything wrong with the USB-SSD
  • With LinuxLive USB Creator the USB SSD doesn't show up at all. (Is that because it is classified as a harddrive rather than a pen drive?)

Edit: I got pass the bug using Rufus. However, Rufus itself seems to have a bug which doesn't allow live USB with persistence for Ubuntu 18.04 LTS. As I wish to use the OS on-the-go, having a drive with no persistence would not be useful =(.

This is an ongoing bug with UnetBootin, it doesn't automatically add the boot flag.

I am not sure about the other software you have used but I can recommend you to use Rufus. It's free software as well. Also it is the recommended software by the Ubuntu official guide for installing Ubuntu on a Windows PC.

Follow this official tutorial step by step.
