I personally don't see much value in dual booting Linux and Windows. Please refer to Windows Emulation on Linux if you need to run Windows apps on Linux.
Mount the Windows File System
When you dual boot your machine with Linux (e.g., Ubuntu) and Windows, the Windows disk/partition might not be mounted automatically. In that case, you can find out which device correspond to the Windows filesystem and mount it manually.
ls /dev/sd*
ls /dev/vd*
ls /dev/nvme*
In Ubuntu, you can open the "Disks" app, which list all disks plugged into the machine.
