So here's the situation:
I have a laptop with a 60GB SSD and 500GB HDD. I decided to make it a dual boot. I installed Windows 10 on the SSD and I want Windows to use 400GB of the HDD. For that, I made a NTFS partition, as you can see in the following screenshot:
The remaining space is for Ubuntu. (root, swap and home)
The problem is that when I install Ubuntu, in "one more thing", it doesn't detect the partition I created in the HDD! The HDD appears as if it didn't have any partition! It detects the SD card and the respective partitions just fine, but it doesn't detect the HDD NTFS partition.
So now I'm unsure how I should proceed. Is there a way to make Ubuntu detect the partition?
Edit: 2 photos of Ubuntu setup
The first picture says "Erase disk and install Ubuntu" and "Something else"
I found a way to trick it! Instead of creating the NTFS partition with windows, I used live USB (GParted) to create it. After that both Windows and Ubuntu detect it just fine.
