  • Download Ubuntu again, and burn it to CD. Do an MD5SUM on the ISO file first. – Mitch Jun 30 '12 at 08:41
  • Does it give you any error messages? – Mitch Jun 30 '12 at 08:41

    You do know you have to set your BIOS to boot from CD-drive first (before the internal HDD)? – Tinellus Jun 30 '12 at 09:26
  • Are you saying your laptop used to be able to boot from CD's and USB flash drives, but is no longer capable of doing so? Or are you saying that you're specifically having trouble burning an Ubuntu CD or writing an Ubuntu USB flash drive that is bootable? – Eliah Kagan Jun 30 '12 at 11:37

That's easy:

  1. Remove your hard disk drive from your laptop.
  2. Connect your laptop's hard drive to another computer (desktop or laptop) using any method: direct connector (laptops), sata or pata cable, usb-to-sata/pata adaptor,etc. This computer should be able to boot from CD/DVD/USB.
  3. You must observe that your laptop's hard disk drive must be the only one connected to the computer, this is needed in order to get a grub clean with just the Ubuntu OS mentioned on it at the boot.
  4. Install Ubuntu.
  5. When finished, just shut the computer down the normal way. Don't restart.
  6. With the computer turned off, remove the hard disk drive and connect it again in the hard disk drive bay of your laptop.
  7. Boot, be patience, the system may delay booting in a different computer.
  8. And enjoy.

This process has been tested both in laptops and desktops and the result is a fresh install fully and successfully working.

Step 3 is very important as if you have another OS installed in a local drive the GRUB will notice and record it to be mentioned in the GRUB's options. Additionally, your GRUB can be written in a different hard disk drive. To avoid these issues simply disconnect all the hard disk drives and maintain only the one where you wish your OS to be installed.

I hope this help you.

Good luck!
