I want to install Ubuntu with Windows 10. After opening GParted, I've noticed that there are about 4 partitions (I don't know what type they are). Then, as most tutorials show, I needed to create an extended partition. I took some space from Windows disk D. After that, I chose that unallocated space to create extended partition, but I couldn't because it was not available to click. I can create only primary partitions. What do I have to do?
I need to create an extended partition so that I can create logical partitions for home, swap and root. Can I do all this things in a primary partition?
