I am trying to dual a new PC I just got that comes with an Asus motherboard.

First thing I done was disabled secure booth and fast booth . Then I shrunk the partion in Windows 8. Then I went to Install Ubuntu from my USB disk and as there is no option to install it alongside windows I chose something else.

My problem is that In the partion table it only shows 1 partion with with around 936 gb of unalocated space and does not recognise any of the windows partions. when using gparted i get this error message:

libparted warning

/dev/sda contains GPT signatures, indicating that it has a GPT table. However, it does not have a valid fake msdos partion table, as it should. Perhaps it was corrupted – posssibly by a programthat doesn't understand GPT table, and are now using an msdos partion table. Is this a GPT partion table?

I have already ignored this and contiued to set up the ubuntu partions following this guide http://www.everydaylinuxuser.com/2014/05/install-ubuntu-1404-alongside-windows.html which didnt work so I have reinstalled windows again to start over.
