Ubuntu – Windows 10 dual boot ubuntu on ssd and data on hdd

Well, here's how I would do it:

1. Create and format all partitions to be used by Windows only.
2. Install Windows 10 in either BIOS or EFI mode.
3. Get a few cups of coffee while this installs.
4. Install Ubuntu from the CD/DVD, and select to use your own partitioning (Make sure to boot from the Ubuntu DVD using the same mode you installed Windows in - BIOS or EFI).
5. Create the Ubuntu partitions.
6. Let it install Ubuntu.
7. Get a cup of coffee while it installs.
8. Check to see that it boots to the GRUB2 boot manager.
9. Boot into each OS and make sure both have Identical network configurations. e.g. IP address, hostname, etc. You might want to add an identifier to the end of the hostname to distinguish which OS you're in, like this: MyAwesomePC-Win10 and MyAwesomePC-Linux.

Installing the / partitioning on the SSD instead of on the HDD will give much better performance and stability, but your partitioning scheme is too complicated and there's not enough space in / . At least 25GB is recommended for / and you'll probably need more than that. We can discuss the exact amount of / that is required. All you need is / and optionally swap and /home, but in new installations of Ubuntu 17.04 and later a swap file is created instead of a swap partition, so you don't need a swap partition either.

The more information that you provide, the more specific the recommendation can be. Let's start with a general recommendation. SSDs are rugged and durable so read and write cycles is not the most important issue. Disk space on an SSD is expensive compared to disk space on an HDD so it's important to conserve valuable space on the SSD by not cluttering it with unnecessary partitions.
