Smile Dual Boot Ubuntu alongside Win 10 UEFI System

Hello I have a new Lenovo G50-80 laptop with the following specs.

Ci5 5200/ 4GB / 1TB / 2GB Graph / Win 10 64bit pre installed

It has Secure Boot Enabled and also Secure Boot on

I want to install Ubuntu 14.04 alongside Win 10 and make it a Dual Boot System. I started by making a USB for Ubuntu and booted using the USB. I choose "Something Else" in installation type.

I will make partitions as below.

Swap 8 GB
/root 50 GB (ext4)
/home 50 GB (ext4)
But I did not know where to place the Bootloader from the menu that is available (See link below). Should I place it in the UEFI partition ? If I place so will it not affect my WIn 10 ?


Also I need Grub as my Boot loader and I will not like to use the Win Boot loader.

Should I disable SECURE BOOT ?

Please do help me. Thank You.

The image you posted shows sda1 as the EFI partition which should be where you install the Ubuntu efi files. It installs the Ubuntu files along with the windows files in the same partition and if you have read any posts on this or seen the content of EFI partitions, you should see both windows and Ubuntu files. I don't use EFI myself so I'll refer you to the Ubuntu site explicity for this purpose.

Good advice from yancek above...
Another resource: [TUTORIAL] Installing Mint on a Windows UEFI Computer
(Applies to Ubuntu, as well as Mint.)

Just to add a little tip: you said you plan to create a 50 GB partition for /
Unless you have some special plans to save lots of files in the / partition, the most anyone would ordinarily need is 15 to 20 GB - any more would just be wasted unused space.
