Unable to boot into windows after partitioning macOS

I just have one disk in my MBP and nothing attached to it. After the first command it gives me 20(!) disks; disk0 is the main disk with all the partitions. After putting in the second command it says "sudo: command not found". Do you know why this is happening? Oh and how do I post the entire terminal result in here? I can't really copy it right?

Okay I boot into macOS now. This is what it shows me after I put in the first two commands. It says I cannot open the device /dev/disk0?

Okay that worked! Now this is the result I get after all three commands.

I have two NTFS partitions. The 301.9 GB BOOTCAMP is normally where I boot to windows. The 59.8 GB NTFS partition is the partition that I created for extra storage for windows. What do you mean by 'MBR' and why/how is it incomplete?

Macbook Pro Mid 2012 ( I replaced RAM and switched to SSD if that info is useful)

it says command not found?

What are the numbers in step 7 and 8? Are they the same for me?

You are awesome! Thanks a lot for helping me with this!
