Below are some links to help you remove Ubuntu and install Windows 10.
I don't think this reply answers the question asked. I believe this individual is saying they have Ubuntu installed on their computer and they want to uninstall that and install windows. The correct answer would be (I believe) to not uninstall Ubuntu, upon boot open the BIOS (probably f10) and change the boot order to boot from whatever source you will be providing windows from (cd, usb, etc...). After this, upon exiting the BIOS, install should begin as normal.
I'm trying to install windows but it keeps telling me that my PC run into an error & will be restarted automatically, what should I do?
