I installed 2 Operation System before. But now, I have been followed the method right click on my computer > go to Advance tab > go click setting on Startup and Recovery section > click edit on system start up section...deleted 1 of them and will not ask me to choose either 1 or 2 OS when start up my workstation.
However, both of the old windows and user folder still in “C” and couldn’t delete.
What can I do? Please advice.
