I have installed Ubuntu along side Windows 10 but need to remove it and install Fedora.

Am I able to fix the MBR before removing the Ubuntu partition?

I realise this question looks like so many others, but its slightly different and I cannot find an answer elsewhere.

Basically I have goosed my MBR numerous times in the past and this time I wanted to ensure all will run smooth.

The solutions I see are to first fire up Windows remove the partition, insert the Windows recovery media and fix the MBR. As mentioned before I have ended up with a dead laptop and had to wipe and restart.

So am I able to first fix the MBR while Ubuntu is still on, then fire up Windows and at this time delete the partition?

    Welcome to AskUbuntu. I wonder why you want to "fix" your MBR that early in the process. As I understand Fedora will probably write it's own flavor of MBR to your disk while installing. This then will (I guess) allow you to boot into a bootmanager to choose to boot either Windows or Fedora. – MadMike Jun 15 '16 at 09:41
  • Thanks for the edit @MadMike. I will look at my formatting in the future. – Adam 'Sacki' Sackfield Jun 15 '16 at 09:41

    No Problem. Also edits aren't meant to criticize, just to (hopefully) make things easier for the next person to read. You can easily rollback any edits other people make. – MadMike Jun 15 '16 at 09:42
  • @MadMike I was unsure how doing it that way would affect my system. As mentioned I have struggled with damaged MBR in the past. I assumed (perhaps incorrectly) that it would cause the least headaches if I first got my system back to just Windows and then went about installing Fedora much the same as I did for Ubuntu. – Adam 'Sacki' Sackfield Jun 15 '16 at 09:44
  • I realise this MadMike and I prefer your edits as they do add more clarity to the reader. – Adam 'Sacki' Sackfield Jun 15 '16 at 09:45

Simply install GRUB to your disk (not to any of the partitions) and that will overwrite the MBR with working GRUB files.

A detailed guide on this can be found here:
How can I repair grub? (How to get Ubuntu back after installing Windows?)

However, this is not necessary as you're going to install Fedora anyway. It will install GRUB during the installation anyway, so that should fix it as well.

If you really want to first remove Ubuntu and GRUB and restore the Windows bootloader though, you have to follow this: How to remove Ubuntu and put Windows back on?

  • Thanks for your response. However, it appears to be the reverse of what I require. I don't want to overwrite MBR with Grub. I wanted to remove Ubuntu and leave Windows as the lone OS as before so I can then start the process again and add Fedora along side Windows. – Adam 'Sacki' Sackfield Jun 15 '16 at 09:59

    If you add Fedora again, that will also install GRUB again and overwrite the MBR. So I think there's no advantage in installing the Windows bootloader to the MBR first.

  • Ah I see. Thanks again. I will attempt to do as your answer states. Will give the tick once done. – Adam 'Sacki' Sackfield Jun 15 '16 at 10:08
  • Actually the link you provided is exactly what I want to do. If you want to post your link as a new answer I will accept that and give it the tick. – Adam 'Sacki' Sackfield Jun 15 '16 at 10:10
  • I added it to this answer. – Byte Commander Jun 15 '16 at 10:11
