Some time ago I installed Ubuntu (14th version) on my laptop along with Windows 8.1 using a bootable CD drive. But now I wanted to remove Ubuntu and so I deleted the partitions that I created for Ubuntu. Now I have to repair Windows boot but I do not have that CD drive from which I installed Ubuntu. Is there any way to repair the boot without original installation drive? Can I create another bootable drive and repair Windows boot from that.

P.S. - The Ubuntu installation process didn't go well. After I installed it alongside windows, whenever I used to start the laptop, I would get a grub screen and I have to type exit in order to go to the screen where it shows the OS choices. There were sometimes mounting problems in Ubuntu.


If you don't have Windows installation DVD available, you can download it from here:


After creating media using the tool downloaded from above, boot from DVD or USB and follow the instructions found here:


Here's quick summary:

  • Select Repair your computer in the bottom left corner.
  • Select Troubleshoot
  • Select Advanced
  • Select Automatic Repair and try to boot normally without DVD/USB connected.

If Automatic Repair didn't help:

  • Go to same place as before but select Command Prompt
  • And use the following command: bootrec /fixmbr
  • Boot without DVD/USB

This Ask Ubuntu question describes a similar situation and has an accepted answer that may solve the problem - How to load Windows 7 from GRUB rescue. Basically it uses the Ultimate Boot CD to enable running the boot recovery commands.


If you have a Windows installation DVD or repair CD, you can boot to a repair command prompt (shift + f10 at the first screen) and run:

bootrec /fixmbr

If not, you can always create a bootable windows USB and install a bootloader like GRUB from there.

  • OP asked a solution without using the 'original installation drive'.
