Ubuntu – Uninstalling Ubuntu from Windows Dual Boot if I don’t have Windows recovery CD

16.04bootdual-bootpartitioningwindows 8

I installed Ubuntu (I had already had Windows 8.1) from USB (I still have live Ubuntu on it). Is there a way I can uninstall Ubuntu in a way that my Windows will remain bootable? All the tutorials I have seen say that uninstalling ubuntu will delete GRUB also so I will need a Windows recovery CD to boot into it, but I don't have one. Is there a solution?

First, create a recovery drive using these steps:

To create a USB recovery drive

  1. Swipe in from the right edge of the screen, and then tap Search. (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Search.)
  2. Enter recovery drive in the search box, and then tap or click Create a recovery drive. Administrator permission required You might be asked for an admin password or to confirm your choice.
  3. After the recovery drive tool opens, make sure the Copy the recovery partition from the PC to the recovery drive check box is selected, and then tap or click Next.

The checkbox is greyed out when your PC doesn’t have a recovery partition. The recovery drive will include only the recovery tools and a bootable image, but not a recovery image to use for refreshing or resetting your PC.

  1. Insert a USB flash drive into your PC that is at least as large as the size indicated on the screen.
  2. Tap or click the USB drive you would like to use for your recovery drive, then tap or click Next.
  3. Tap or click Create.
