1) If you want to install Ubuntu+Windows 8 this is called "dual booting"

2) If you want install Ubuntu+Windows 8 + some other OS(s) this is called "multibooting".

It looks like you want to dual boot and not multiboot.

If you want to dual boot start by looking here: http://www.everydaylinuxuser.com/2013/09/install-ubuntu-linux-alongside-windows.html

I had the same problem once. Probably your windows 8 has a feature called Secure Boot, this makes really annoying to install any other OS, since you can't see with the default procedure the W8 OS, what makes mandatory to format the whole disk or you can use the Something Else.

Now this is tricky. You can damage you W8 OS if you just install ubuntu over, even if you make more partitions.

First, you need to re-install W8 and create the partitions of your system. Like:

- 200 GB -> W8
- 200 GB -> Data
- 100 GB -> Free

After that you can install the Ubuntu in the Free partition, but you need to use the Something Else option. Then you create:

- Swap partition: with the size of your RAM (or 2 times, my choice)
- Ext4 Partition: With the rest of your free space, where you will put your Ubuntu. Mount point: /

And let the installer to do the rest of the job. After that, I turned off my Secure Boot option, in the BIOS menu.

This is the way I solved, I'm sharing it because it may help you, but the link arochester gave you will give some more accurate info about the procedure.

The only thing is that I couldn't install the Ubuntu only by using the partition tool on W8, I had to re-install it.

Good luck

If you like to run a multi boot machine, you bootloader must be grub, you can not boot a linux machine with a windows boot loader, please install windows and then go with the installation of your linux machie.

I had a multi system "windows 7 and CentOS 6.5". After change windows 7 to windows 8.1 GRUB disappeared and now CentOS is unavailable. Please help me to restore GRUB again.
