Ubuntu: Where to install bootloader when installing Ubuntu as secondary OS?


I'm trying to install Ubuntu as secondary OS on my laptop. I have Windows 8 already installed on my laptop.

Now, I know how to run Ubuntu from USB drive, I created addition partition and formatted it to EXT4.

So I'm ready to install.

Now, 'Device for boot loader installation:' displays:

/dev/sta ATA HITACHI (750 GB)  /dev/sta1 Windows 8 (loader)  /dev/sta2  /dev/sta5  /dev/sta6 Ubuntu 12.04 (12.04)  /dev/stb  

I tries choosing Ubuntu 12.04 partition but it doesn't even let me to pick which OS to install and goes straight to Windows 8.

Which partition I must choose to be able to pick which OS to boot from? Preferably, set up so Windows 8 will be at first place, and Ubuntu on second.

Any ideas? I don't want to mess up anything if I pick something wrong.


Here's an example that could help you out:

Installation type

Under "Device for boot loader installation":

  • if you choose dev/sda, it will use Grub (Ubuntu's boot loader) to load all systems on this hard drive.
  • if you choose dev/sda1, Ubuntu need to be manually added to drive's boot loader after installation. (for example, you previously have Windows installed on another partition of this drive, you'll need manually add Ubuntu into mbr)

These two could also be relevant to your question:


Out of my experience:

  • if the boot system is legacy/BIOS, choose the device /sda straight away. Even suggesting other possibilities had been earmarked as a bug (https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1049549)
  • if the boot system is UEFI, choose the partition /sda. (note the dot for a number) where the UEFI files are stored. You can launch gparted to see which this partition is by looking at where the tag 'boot' is the column 'Flags'.

These solutions had me reinstalling Ubuntu 14.04 without compromising the dual-boot menu at start up.

If you are uncertain about the sort of bootstrapping in your machine, consider the post Is my windows booting in UEFI Mode or Legacy Mode?
