How to work with WinAPI files from assembler?

Question

assembler

DeleteFile("\\comp1\user1\test\test1.txt");
It's understandable, it's easy. And how can I, for example, delete or write some information to a certain sector of the disk? For example, write your bootloader to the boot sector? I need to write this for Windows in assembler. Or do I need to write a driver?

Answer 1

How can I, for example, delete or write some information to a certain sector of the disk?

Open the drive as a file (file name -- \\.\PhysicalDriveX, X = 0...), then everything is the same as with a file -- SetFilePointer, WriteFile, ...
You don't need an assembler for this.
