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