Recently I bought a asus vivobook notebook which has genuine win 10 home pre-installed. But I have installed ubuntu 16.04 alongside it. For doing so I had to shrink the partition in which windows is installed. I have done it with windows' built in disk manager. Now I want to make a recovery disk so that I can recover my genuine windows in future. So I go to Control Panel\All Control Panel Items\Recovery And clicked Creat a recovery drive Then Next on the new window. But after that it says

We can't create a recovery drive on this PC Some required files are missing.

But as shown in Fig1 windows has a recovery partition in disk1(last partition). Is it the shrinking that caused this damage? If so what are the alternatives to recover my genuine windows now? Or how can I help myself with that recovery partition on my hard-drive and what is it for? Or is it anything else that causing this problem?

  • The recovery partition is just for that, to restore the factory installed OS.....youtube.com/watch?v=pc3OamFf9-I – Moab Feb 18 at 18:02
  • There is no 'reset your pc' option in my case @Moab – Tangent Feb 18 at 18:21

Start by running sfc /scannow to check the integrity of Windows. It will tell you if any Windows files are missing.

If the SFC scan finished correctly, try this method coming from the post Can't create a Windows 10 recovery drive. Some required files are missing by a user called Criostoir O'Dochartaigh:

Open command prompt in elevated mode and type:

reagentc /disable

then type:

reagentc /setreimage /path \\?\GLOBALROOT\device\harddisk0\partition1\Recovery\WindowsRE

Then type:

reagentc /enable

You may need to change "harddisk0" to "harddiskX" where X is the number of your "C" drive and "partition1" to partitionX where X is the partition number to conform with your system setup. To check go to Control Panel/Administrative Tools/Computer Management/Storage/Diskmanagment. The disk partitions are numbered from the left of the screen starting with number 1.
