I recently installed Win7 and Ubuntu 12 on a new build.

Installed windows first, as recommended, and then Ubuntu on the remaining unused drive space.

Everything was working fine, grub allowed me to dual boot properly. Until this morning - switched the machine on, and it booted into windows - no grub.

I'm wondering if a recent windows update may have overwritten the MBR?

So..

  • What's most likely to have caused this?
  • How do I get grub back?
  • How do I stop it happening again in the future?

Thanks!

  • Install EasyBCD community edition on Windows 7. Goto new entry -> then Make a entry using "Grub 2". Change "Neo****" to "Ubuntu 12.04" - > Go to Deployment -> Write to MBR – Curious Apprentice Jul 1 '12 at 10:21
  • Try Boot Repair. – Mitch Jul 1 '12 at 10:32

As Mitch has suggested you will need to run "Boot Repair"

You will need to do this using a Live CD/USB see here https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows for full instructions

  • Ok thanks I'll try that - but I still don't understand why it happened. It's not something that I want to have to do regularly! – UpTheCreek Jul 1 '12 at 16:26
  • I'm afraid I can't tell you how it happened but I can say that it should not be a common occurrence. I have set up several machines for dual boot and never known it to happen unless Windows is installed after Ubuntu – Chris Carter Jul 1 '12 at 16:33

Is it possible that Windows was hibernated ?

When you power on after hibernation the hibernated system is starting - you do not get a boot menu.

So maybe there is nothing wrong with your dual boot. You will know after rebooting.

  • Hi, I'm facing the same problem, I had hibernated once. After that the GRUB stopped showing! – Dushyant Bangal Mar 10 '16 at 5:05
