Windows 10: Putting windows back on a laptop that had ubuntu on it

I purchased a HP Pavilion x360 a little over a year ago that came with Windows 10 Home on it. A few months after purchasing it I switched the OS to Ubuntu. However, now I want to switch back to Windows 10 Home. Do i need to purchase Windows 10 Home or is there a way that I can download it without having to purchase it?

Help with dual booting Win 10 and Ubuntu

This is your whole problem. What you should have done is to put GRUB in sdb1 and Windows Manager in sda1 so that Windows Boot Manager is in control.
So what suggested above will not make any difference. GRUB is still in control of booting process.
To fix your problem. You will need to:

1. Move GRUB from sdb to sdb1
   |grub2 - how to move grub boot from one partition to another in linux - Ask Ubuntu
2. Rebuild The Windows Boot Manager ie. create a brand new BCD to boot Windows 10.
3. Once done with steps 1 and 2 above. Windows will not know UBUNTU exists and vice versa.
   Depend on the priority set in the BIOS, it will boot directly into that OS.
   However, you can boot either one from Boot Menu (Using whatever key that your Laptop assigned to: F2, F10....)
   Since I hate Dual Boot and seldom boot into Linux, I will stop here.
   Now, go to step 4 to create dual boot.
4. Use Easy BCD to create an entry for dual boot with UBUNTU. Once done, you should get a nice GUI dual Boot Menu
   and it will boot directly into either Windows or UBUNTU.

Here's the detailed explanation: How can I move windows 10 boot files to another drive to allow linux

 

Networking issue - Windows and Ubuntu

Went on a short trip, took my Windows 10 laptop, turned off the Ubuntu computer and my wife's Windows 10 computer. When I returned, I turned everything back on and nether Windows computer could see the Ubuntu 16.04 LTS computer. On the Ubuntu computer, Files/Network clicking on Windows Network received "Unable to access location - Failed to retrieve share list from server: No such file or directory" error. Both Windows computers were able to use the Ubuntu before the trip.

Any suggestions?
