I have LAPTOP ASUS K55V (Windows 7 Home 64bit) (I'd like to dual boot with Ubuntu)

I read all the tutorials about install Ubuntu, here's what I did:

  1. Installed old version (problem: There some some Windows partitions and I can format some of them) (Backtrack 5R3 won't boot)

  2. I download the latest Ubuntu. I have boot option set as UEFI/EFI. I then ran GRUB and Ubuntu worked. (problem: GRUB can't boot into Windows (problem 2: Windows updated and now GRUB can't find the partition)

I now can't turn off UEFI/EFI even looking at the same tutorial.

My question is: How to install? or How to turn off boot UEFI/EFI on my PC?

I have a EFI partition, could that cause a problem?.

Please run the Boot Info Script from Linux and post a link to the RESULTS.txt file that it generates. Without the information in this script, answers will be based on (possibly incorrect) assumptions. – Rod Smith Jun 17 '13 at 16:13

This is how I made it work :)

you will nead the latest ubuntu (i use ubuntu-13.04-desktop-amd64) choose the correct version for your computer

In windows open windows disk management

  1. make c partiton smaller (i cut 25 GB)
  2. Boot USB/CD in EFI/UEFI
  3. I chose install on the FREE space :P (it is good)


  1. you wil get new boot option in bios : ubuntu
  2. make this option first in list (((importent))
  4. INSTAL Boot-Repair
  5. do repair
  6. now you have got windows 7 and ubuntu 2boot 10.
