I am trying to dual boot Windows 10 and Ubuntu 18.04 . I have Windows 10 pre installed on a 466 GB HDD using Dynamic Disks, with three partitions (150 280 150) approx, and 78 GB unallocated (made by shrinking an existing partition), which you can see at
I have made a bootable USB for Ubuntu. Whenever I go to the installation, it doesn't shows me the 'Install Ubuntu Alongside Windows' option, so I chose 'Something else'.
At the time of installation, it shows me only 2 partitions ( One of 125gb and one of remaining 350gb of my hard drive.) I am unable to see other partitions and unallocated space.
ANY SOLUTIONS? PLEASE ASAP.
