So, in the first picture, I have a partitioned drive "Ubunut (D:)." From my understanding, that should make it to where I can load Ubuntu onto that volume, thus having the ability to dual boot Windows and Ubuntu on two seperate hard drives.

But as you can see in the second picture, when I get to the installation screen of Ubuntu, there are no volumes that say "195.31 GB." I'm afraid to download it onto any of the others because I'm too unknowledgeable about this stuff, and I feel like it'll wreck my computer.

We repeatedly rewrote small, randomly-selected regions of four
100MB files on each external card, and measured the wear-out
indicator, shown in Figure 2. The results show that the required I/O
volume is mostly constant throughout the lifetime of the devices.
Specifically, it takes a maximum of 992GiB to increment the wearout level by 10% in the 8GB eMMC chip. From the OS’s perspective,
this is roughly three times lower than the “back-of-the-envelope”
three thousand or more complete rewrites. Moreover, at a maximum
