This question already has an answer here:

I have recently become interested in trying out Ubuntu 15.10, just for the sake of fun. However, I am confused as to how to dual boot Windows 10 and Ubuntu 15.10 on my Toshiba Qosmio X75-A7295

The computer is a rather high-spec one, with one 256 SSD on which Windows 10 is installed (as in, any important files required to run Windows 10), and a 1 TB hard drive that is used to hold any extra files, like documents and what not.

The 256 GB SSD is almost full, leaving only the 1 TB hard drive open for installing Ubuntu.

However, the computer is EFI boot, so I believe that the boot partition is on the SSD

What advice would you give me when attempting to install Ubuntu in a dual-boot set-up?

  • First boot into a Ubuntu Live CD/USB and provide us with a screenshot of your partition table either by using Gparted or lsblk -f. Someone will give specific instructions for you then.. – Gayan Weerakutti Nov 7 '15 at 18:08
  • I'd partition a space on the 1 TB drive and use EFI mode and the EFI boot management process to pick which OS I used at boot time. – KGIII Nov 7 '15 at 18:13
  • Also make sure to boot your Live CD/USB in UEFI mode. – Gayan Weerakutti Nov 7 '15 at 18:15

I would suggest make a different 20 GB partition for Ubuntu, and with windowsUbuntuinstaller you can easily install Ubuntu on your windows 10 like an application of you windows machine. when you are tired with Ubuntu just uninstall it from control panel just like any software.
