I just installed ubuntu 12.10 64bit on my hp probook 4540s windows 8 laptop, After installation I cant boot into ubuntu, the system boots directly into my windows.

Here are my installtion settings...

  1. I turned off Fast Boot on Windows 8
  2. I turned off Secure Boot
  3. I changed from UEFI Mode to Legacy Mode(because ubuntu was not installing from a liveusb when uefi is on).
  4. I created three partitions, one for swap, one for / root partition, and one for /home partition.

After installation, I installed boot-repair and run a boot-repair on the system.

After the boot-repair process, I changed back to uefi mode and it boots directly into windows.

I tried using BCD but it was only seeing the windows bootloader and no ubuntu.

Please how do I make this work..

Do you mean 13.10? If so I recommend you edit your question. Otherwise I would try using 13.10, 12.10 was the first ubuntu to support UEFI so I imagine they have improved support a lot since then.

Do not try to install in BIOS/CSM/legacy mode when the computer is already booting another computer in EFI/UEFI mode. You might clear an initial hurdle relatively easily this way, but you'll be setting yourself up for bigger problems down the road, as you've discovered. It's usually possible to get the installer working in EFI/UEFI mode. On rare occasion, a BIOS/CSM/legacy-mode install may be required, but this is an option of last resort.

Unfortunately, the possible causes for your initial problem are numerous, so I can't provide you with a simple procedure to overcome your problem. I do strongly recommend using a more recent version of Ubuntu, though. Also, read at least one, and preferably all three, of the following pages:
