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

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

current partitions

Partition manager 1.

Partition manager 2.

It has Secure Boot enabled and also Secure Boot on.

Secure Boot / UEFI Info

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. Should I place it in the UEFI partition? If I do so will it not affect my Win 10?

Bootloader Option

I need to use GRUB as my bootloader and I don't want to use the Windows bootloader.

Should I disable SECURE BOOT?

No you don't need to disable secure boot. Just make sure to boot your Ubuntu installation media in EFI mode. Then set mount points for the root, home and swap.

Keep /dev/sda for the bootloader installation as it is. Ubuntu installer (grub btw) is smart enough to detect your EFI, and non-Linux partitions.

Your swap space is too large though.

Install the bootloader in /dev/sda as it is the main partition.

Also, you need to disable the secure boot in order to install Ubuntu.
