How to change SYSTEM drive letter to C from another letter

I am working on a step by step process to fix the computer for windows 11 upgrade. (Currently have Windows 10) This was a built PC, but when my friend installed the OS for me somehow the windows install drive became the F drive. Here is a view of disk management I want to do the following (believe I need to do in this order).

1. Move windows install drive letter from F to C
2. Fix it so bootloader is MBR / on the SSD

Afraid of just changing the letter in disk management as the system will look for system files in the f-drive. I do have AOMEI partition assistant installed if that is useful for this task. I really appreciate any help in how to do it.
