This question already has an answer here:

I am currently trying to install ubuntu 13.10 to dual-boot with windows 8.1 on my laptop. The laptop is a Lenovo Ideapad z400 touch. I am getting stuck at the Install Style screen because the installer is not recognizing windows being already there and I don't know how I should do the partitioning manually. The boot-repair pastebin is here. I have about 70 GB of unallocated space on my hdd for ubuntu.

Here is the lbsk output:

ubuntu@ubuntu:~$ lsblk
sda      8:0    0 931.5G  0 disk
├─sda1   8:1    0  1000M  0 part

sr0     11:0    1  1024M  0 rom  
    loop0    7:0    0 842.7M  1 loop /rofs 

Here is the sudo blkid output:

Hi @thatGuy I have updated the marked duplicate question with several steps to Windows detection. This are tested and work correctly for cases like yours. – Luis Alvarado Mar 4 '14 at 17:14
Thanks I will checked it out. – thatGuy Mar 7 '14 at 14:42

Read the following thread it's similar to your post and you can also read the documentation on DualBoot not to miss anything.

I have looked through several threads with this type of question and have tried all of the solutions that I have found with nothing working. About the thread linked: When I run fixparts I get "This disk appears to be a GPT disk. Use GNU Parted or GPT fdisk on it!" I try to run gdisk as it said to do and did the commands that I have found about the error/warning on other threads, but the problem still happens. I have read through the dual boot docs and haven't found anything for my problem, except for the DiskSpace, which helped me understand a little better how it should be done manually. – thatGuy Dec 1 '13 at 23:58
Did you read the tutorial in the comment above? It's actually about GPT disk as well. – Surfer Dec 2 '13 at 0:09
I did and still get it not recognizing windows 8 being installed. – thatGuy Dec 2 '13 at 1:03
Do you have BIOS-Boot or EFI partition? it's required on GPT disks. Type sudo parted -l and see what it says. – Surfer Dec 3 '13 at 19:17
If you want to install Ubuntu on a GPT disk you will need either an EFI partition (if your BIOS is setup in EFI mode) or a BIOS-Boot partition (if your BIOS is setup in Legacy mode). – Surfer Dec 3 '13 at 19:22
