My laptop is Dell inspiron R15. It comes with Windows 8 64bit, Chinese Home Edition. I later upgraded to Windows 8 64bit, English Pro. Edition. Then I installed Linux and setup dual-bool. Now, I can see the Windows 8.1 update in the Windows Store. I have 8GB memory installed, and about 90GB free disks pace. My nVidia driver is up to date.
Here is my update log. Some people say the failure is caused by conflicts, and the log can tell you. But I could not find anything useful to help me locate the conflicts, if any.
Couldn't update to Windows 8.1
