Question:

How do I get back to Windows after running Ubuntu?

Answer:

1. If you want Windows and Ubuntu to work normally on your PC. In the case of installing from scratch (a new "clean" PC), I recommend installing Windows first. If you install Ubuntu faster than Windows, there will be problems.
2. If you already have Windows is installed, feel free to install Ubuntu next to it as a second OS. Be careful during installation at the moment with Sections
3. After Ubuntu is installed, you can change systems via the F11 key, which you must press during boot, when the system starts to boot.
   Although there may still be different points, but in general the principle is the same.
