Trouble partitioning hard drive for dual booting

I'm throwing myself in the deep end learning about Linux and I'm trying to install Kubuntu alongside Windows 10 as a dual boot. I have a 2TB HDD which was partitioned into 4 partitions, I've shrunk one and created another drive for Kubuntu, but looks like I've messed it up.

I have 2 partitions for Windows system stuff, C: and D:, both C: and D: are about 991MB, I've shrunk C: by 32GB and created L: which took up the remaining space.
I must have done something wrong there because now my partitions are simple volumes, the internet seems to tell me that's a problem but not exactly why or how to fix it. When I try to install Kubuntu from a USB the installer tells me I have the system drives, C: and 1TB of empty space, rather than the remaining two drives.
I'm wondering where I've gone wrong in this and if there's a way to change the partitions back without losing all of my data, I have many gigs of important programs and projects I would very much rather not lose or have to reinstall (it's ~$5000 software which I have a student licence for, I'd like to not have to go through the verifying process again)
 
More than likely it is because when you made that other partition it made a logical drive and then made a partition inside of that. I don't know if linux can install to a logical partition.

Can you boot into windows and post a screen shot of your disk management there and your partitions?

Luckily Windows still boots fine, just seems a bit slower. Here's my disk management screen if it's any help.
