I am on windows 10 (Upgraded from 7). Trying to install ubuntu but at the 3rd step it just shows /dev/sda. I actually have 4 drives and unallocated space. Live boot from USB drive shows the partitions perfectly. I heard about that 4 drives issue too but that question comes later, right? I can't even see my 4 drives in installation process. I checked that my windows 10 boots in legacy mode & ubuntu too (because media loading screen is a purple screen not black & white terminal-like one). I disabled fast boot. I also followed the instructions in this question. But it doesn't apply since sudo fdisk -l /dev/sda
says I have only MBR partition table present. So I am out of clues here on what to do now
Found Libparted Error while opening GParted: 1) Can't have overlapping partition 2) Can't have a primary partition inside an extended partition
