I try to boot Ubuntu 12.04, 64-bit on my Compaq CQ58 laptop from a USB but it is not working. I've correctly installed the Ubuntu on my pen drive following the instructions on Ubuntu website. (

These are my BIOS settings:

Post Hotkey Delay (sec) <0>

CD-ROM Boot Internal Network Adapter Boot Network Boot Protocol Legacy Support Secure Boot Platform Key Enrolled Pending Action None Clear All Secure Boot

UEFI Boot Order: USB Diskette on Key/USB Hard Disk OS Boot Manager Internal CD/DVD ROM Drive ! Network Adapter

With these settings when i restart my computer what shows up is:

Boot Device Not Found.

This is what I get on the Boot Manager:

Boot Option Menu

OS boot Manager Boot From EFI File

(Arrow Up) and (Arrow Down) to change option, ENTER to select an option.

Press F10 to BIOS Setup Options, ESC to exit.


P.S. My laptop has windows 8

Here is a guide from someone who seems to have encountered this… (usually I would paraphrase into an answer but as I don't have this laptop this is a suggestion of something that might work but I can't confirm) good luck! – captain_G Oct 26 '13 at 22:10
