I have tried to install Ubuntu 14.04.4 using a live USB, but GParted and the Ubuntu installation screen does not list any partitions (only lists the drives as sda, sdb, and sdc) and shows my 2 SSDs and 1 HDD as unallocated. I have tried looking at different posts on Ask Ubuntu, but none of them have helped. Any help would be great.

  1. My Laptop Details:
    • sda is a M.2 SSD with Windows 7 installed
    • sdb is a M.2 SSD with Windows 10 installed
    • sdc is a HDD with 2 partitions
      1. Partition containing data
      2. Partition where I wish to install Ubuntu

My Paritions from Disk Management view on Windows 10

I installed Windows 7 first, then installed Windows 10. Now I wish to triple boot with Ubuntu and I do not mind the GRUB boot loader but would prefer the Windows boot loader.

  1. I tried running the sudo fdisk -lu command, but I am not sure how to interpret the data

  2. Other things worth mentioning

    • I previously had a RAID 0 with my 2 M.2 SSDs however, I have wiped my drives and reinstalled operating systems on it about 2 times since then
    • I once had Ubuntu installed on this computer, but I wiped my drives and installed other operating systems since then

Any help would be great! Thanks.
