Ubuntu: No bootable device


I know this isn't exactly a Linux problem but I'm getting no help anywhere else. I'm trying to reinstall ubuntu onto my laptop but I keep getting the error "No bootable device -- insert boot disk and press any key" but I have it on my USB ready to install but for some ready it won't recognize it at all. I've tried everything I could find on the internet and none of them are useful, please help!


Assuming your computer supports boot from USB, you may have to enable it to do so in your BIOS settings. Access the BIOS settings by pressing the appropriate key at startup (varies from machine to machine, typically one of the function keys. google your machine to find out what it is), then go to the boot options and ensure boot from USB is enabled.

If this fails, it's possible the USB you created is no good and you should try putting a fresh image on it. unetbootin is popular and has a reputation for not causing as many errors as other similar utilities.


Sounds like you're using a UEFI system. When you create usb installers they are typically for mbr bios only, it depends what program you use to make it. Install using a DVD and it should work fine.


I had the same problem installing ubuntu! Here is what to do.

  1. Boot to BIOS
  2. On security, make USB on the top.
  3. Make sure that the USB has a good copy of ubuntu
  4. Click 'try ubuntu'
  5. install efibootmgr
  6. Change so boot order so ubuntu is at the top
  7. Unplug USB
  8. Reboot
    It worked with my computer. I'm sorry if it doesn't work with yours.
