We have a case with two operating systems Windows XP installed on the same partition. When you start the computer, the black screen we are asked what operating system we want to enter.
If installing two operating systems was made "by mistake" (it happens to give Installation Windows xp directly from "My Computer :)) we can choose a system based on who to use it, and the other system we can get it Uninstall / delete.
How can delete Windows XP operating system if we have two systems installed on one side.
1. First we have to decide what Windows XP installed on the PC to stop and check which is the folder where Windows XP is installed we want to keep it. To see which Windows folder, open the Run box and type "% windir%". Enter or OK.
2. Check in the top bar of Windows Explorer which is partition and system folder.
