Mirrored Volume of Windows to Ubuntu RAID 1

I am dual booting Windows 10 and Ubuntu 18.10. The D: Drive has a mirrored volume on another hard disk. I am trying to use mdadm to setup similiar mirroring on Ubuntu so that, regardless which OS I boot, the data in D: drive is mirrored.

Drive D: is mounted as /dev/sda1 and the volume where it's mirrored is /dev/sdb1

Questions:

Can I enable mirroring without loosing any data?

Is it possible to mirror just a partition as opposed to entire disk?

If possible, will it break the mirror in Windows? (as I'm dual booting)

What I have tried

I have tried to use webmin GUI to create a mirror however I am not sure what to select here as the mounted partition does not appear on the list.

webmin

Left: Webmin, Right: Highlighted two mirrored partition and their mount location

Thanks for any help.

Probably impossible, as windows does not support mdadm. You can, however, maybe use Dynamic Disks in Windows, which is supported by Linux. This page may give some information. I have never tried, and this is just the result of a quick google search...
