I have installed Ubuntu 12.04 from a live CD. Ubuntu 12.04 is the only operating system on my pc.

My boot settings in the BIOS are:

  1. boot device CD
  2. boot device hard drive.

I installed Ubuntu without any problems. BUT my system will not boot without my live CD.

Every time I try it says :

Reboot and select a proper boot device.

What should I do? I ran a boot repair and I have the URL to paste here http://paste.ubuntu.com/1476459/.

  • Hi tzhou. What is your hardware? – don.joey Dec 29 '12 at 20:24

You should try making the hard drive the primary boot device if you want to boot from it instead of the CD. Set 1 to HDD, and 2 to CD and see if it makes a difference.

  • no difference. i made it a lot of times :) – thzou Dec 29 '12 at 19:09
  • Most computers will bypass the CD drive anyways if it's empty. Can you give us more details on what exactly it's saying? Also, is the bios saying it or is it a message from the OS itself? – KI4JGT Dec 29 '12 at 19:23
  • Reboot and select proper boot device. or insert boot media in the selected boot device and press enter. That is what it is saying. i dont know where it came from Os or bios – thzou Dec 29 '12 at 19:26
  • I've actually experienced that before. My experience it was from the bios and it was because I had accidentally erased the bootloader of my harddrive. – KI4JGT Dec 29 '12 at 19:38
  • hmm so what i should do? – thzou Dec 29 '12 at 19:40
