I had problems while installing ubuntu 12.04 on a samsung laptop, the problem is the AHCI sysmtem, after a lot of searching, I found that this is almost impossible to "fix" and the only way i found is too much work.
I want to install Ubuntu in the 110GB free partition of my hard drive, along with windows.
I have a 150GB Windows partition, a 200GB documents partition, and I want to use 110 GB for Ubuntu.
The problem is that with the liveCD the installer and gparted shows that my entire hard drive is unallocated (the problem of AHCI).
The only way to fix this is to do a lot of work, with a lot of risk, so the question is whether I can install Ubuntu without using either the LiveCD or Wubi.
