dual booting 2 os

[hrkansagara]

harddisk drives : 2
1) 7200 RPM
2) 5600 RPM

already installed os :
1) windows 8.1 with update(november 2014 update)
requirement os :
2) ubuntu linux(any version)

alert(special mention) :
windows 8.1 is on 7200 RPM one hard disk with UEFI boot mode.

my query :
is there any ubuntu setup available which i can run from windows 8.1 to install ubuntu in 5600 RPM hard disk?

notes :
- ubuntu 15's wubi setup already rejects to run from UEFI boot mode on windows 8.1
- install device is usb pen drive with size 8 gb
- computer has no cd/dvd drive.
- guide for the same task to install we be appreciated.
- do not send direct links to ubuntu's official site with complicated guides as i have no time to read and make try and error with many methods

I think u got it wrong as already installed OS is win 8. He is trying to install ubuntu

Turn off fast boot and secure boot. Then install ubuntu. Windows boot manager will be replaced with Grub 2 boot menu. Everything will be fine

Incase u haven't done it, u need universal usb installer software(just google it)
. It will make your pendrive bootable. There u have to just point the ubuntu iso file and the pendrive. software will do the rest. then follow post #4

thanks sarkar bro for this advice but as you stated windows boot loader will be replaced with grub bootloader. i want my windows boot loader to stay default boot loader. is there any way i can retain that boot loader?

special mention :
- by the time of this post ubuntu linux is already installed and now default boot loader is grub boot loader. reason for this step is that i want linux as 2nd os only used frequent and i does not want my default windows boot or os to get affect by it in any way.
- do not suggest to use easybcd software as guide on ubuntu site clearly states that 1st you have to write windows then linux in mbr boot record which means my current boot entry may get damaged if i write new boot record. 2ndly it states windows 7 in guide where as i am having uefi boot manager in my windows 8.1 and not even windows boot manager.

fyi : uefi is new boot mode and i am having both os with uefi boot support in on state. only windows 8 and newer has this uefi support and in linux may be ubuntu 12+ has this uefi support.

I have ubuntu 14.04 & windows 8.1 both installed on my laptop.
Windows 8.1 is default OS. In bios UEFI is default boot option.
When I need to boot ubuntu, I just pressed F12 during bootup & select Ubuntu to start.
My laptop had pre-installed windows 8.1 . I installed Ubuntu Desktop using Live DVD.
