I am trying to make a dual boot ubuntu/win8 on my new laptop, that came with a pre-installed windows 8. After leaving some 300 Gb unpartitioned space in Windows I created a live USB and booted it on UEFI mode, then I launched the install as detailed in here. However, the options for installing next to windows or erasing windows do not come. Instead I have an empty partition window.

I read somewhere that the RAID drivers of Ubuntu might be a problem, so I tried to disable them with sudo apt-get remove dmraid, and then I did got the options for creating a partition table, but no Windows 8 installation was detected, which might be logical, since all my volumes are RAID administered (I could see that in my BIOS).

So what I am after is a dual boot with windows 8 on raid administered volumes. I mention that I have a 32 GB SSD cache, but I want both OS-es on my HDD, and if possible to get the SSD benefit in Ubuntu as well. So the links on installing win7/ubuntu on a raid ssd do not help me at all.

I don't know what RAID does and if the SSD is the real reason, and it would also help me if I could at least see the windows partitions using my live USB, so maybe you could help me with that too?

RAID on a laptop is something weird since it requires 2 or more disks... –  Bruno Pereira Aug 1 '13 at 8:15
    
Yes, I did mention that I have a 32 Gb SSD besides my HDD. –  grokkaine Aug 1 '13 at 8:20
    
Sorry, I meant 2 identical disks, unless you want to have a at best a RAID0 setup of 2x32Gb I do not see the point. Please add more information about your hardware setup to your question, that will make us understand better what you are trying to do. –  Bruno Pereira Aug 1 '13 at 8:25
    
Oh, and your RAID was created with Windows (and you needed to convert your disk volumes to dynamic), Ubuntu will not be able to see and use them for anything. –  Bruno Pereira Aug 1 '13 at 8:26
    
I have one HDD of 1Tb and an SSD of 32 Gb. The Raid appears to control the HDD, not the SSD. In the device specifications they say it has a single SATA HDD of 1Tb. The laptop is a "hp pavilion 15 ultrabook 15-b104eo". Looking in Windows under device specifications I see two Raid 0 volumes .. maybe they are logical volumes. Hmm .. the RAID controller is for the SATA HDD. Thestorage controller is called "Intel Mobile Express SATA Raid Controller" –  grokkaine Aug 1 '13 at 9:39
