Recently I installed windows technical preview to test the features. So currently I have 2 operating system listed in boot menu. Windows 8.1 & Technical Preview( I installed Windows technical preview in other drive and that installation was not a update from previous version ).
So how can I remove the technical preview ? Initially I though to remove all the OS files from the harddrive.But I guess that it may cause some issues on booting. Could you please suggest me to remove the latest OS safely?
