  • How to remove Ubuntu and put Windows back on?

    16 answers



  • Unable to boot into Windows after installing Ubuntu, how to fix?

    17 answers




I'm using a Lenovo Ideapad u330p. It came with Windows 10 preinstalled.



I installed Ubuntu 16.4 on a separate partition and the default boot loader was replaced with Grub 2.



I have since uninstalled Ubuntu but found I was unable to boot from a UEFI USB or CD/DVD device through Grub.



I uninstalled Grub hoping it would default to the Windows Boot Loader. This wasn't the case. I now receive the following error message;



"System boot order not found. Initializing defaults"



The system then resets and gets stuck in a loop with this error message.



If I load the boot order menu using the Novo button I am able to launch windows. However changing the boot order in the bios does not persist when I exit, as such I am still unable to use the windows boot manager to install anything.



Further more, I am unable to access the partition that Ubuntu was installed on.



It cannot be seen or accessed from within Windows.



Can anybody tell me how to;



a) Wipe the hard drive completely and reinstall an operating system?
b) Repair the boot loader?
c) Access the partition that Ubuntu was installed on? (It is on an LVM partition)



Any assistance would be greatly appreciated.

The easiest way is to format and reinstall, but you might be able to use Hirens Boot disk to repair the MBR.
