I have created a Live USB for Ubuntu 13.10 64 bit using Universal-USB-Installer-1.9.4.4

I have restarted and booted from the USB; tried Ubuntu without installing. Everything works fine there including web browsing, videos, installing new software etc. So I decide to install Ubuntu as dual boot option to Windows 8.

When I tried installing, the options do not show the existing Windows 8 OS. It shows only the option to install Ubuntu as standalone OS. The step by step installation instructions available online mention that it should show option like "Install Ubuntu alongside Windows 8"

I have a Dell Inspiron 3521 with Windows 8; UEFI boot. I have 3 options for the boot menu: "UEFI Security boot On", "UEFI Security boot Off" and "Legacy boot".

Please advise how I can get to dual boot Windows 8 and Ubuntu. I know that USB setup is good as I am able to boot and try from it without installing. May be boot settings?

Thanks in Advance! ~KK

  • Choose something else option,select the partition you want to install ubuntu.Please dont select any windows partition.Then format the selected partition to ext4 filesystem,and choose the install option.It will take you to the installation progress window.

It did cross my mind but I don't want to lose my Windows 8. If I do so and Install Ubuntu, will I see both Windows and Ubuntu in boot menu? –  mantlex Nov 14 '13 at 1:20
    
you see both windows and ubuntu on boot menu.But make sure that the partition where you are going to install ubuntu is not a windows c drive partition. –  Avinash Raj Nov 14 '13 at 1:24
