can you help me please? I messed up my boot partition and I don't really know how. I tried to install grub wherever I could and accidentally formatted MBR.

Bootrec.exe /FixBoot doesn't work Ubuntu Bootrepair says operation was successful, but laptop can't boot from hard drive.

http://paste.ubuntu.com/15314979/ this the report from Boot Repair.

Do you know any simple way to fix my boot, some live CD?

If you have a Linux live CD (such as Ubuntu 14.04 LTS), you can install the linux "Boot Repair" program that can sort things out for you, once you're in the Destop environment open a terminal and run the following commands one by one:

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

This will install the program - open it up and you will see the following:

Boot Repair Main Screen

You can use the options displayed as well as the "Restore MBR" function to solve your problem, this should work perfectly.

It may also be worth working through the other options tabs, particularly the MBR options tab where you can choose the primary hard drive and OS:

Choose OS to Boot

Let me know if you need anything else.

  • I doesn't work. "Please install an operating system on your hard disk". Also, in new version of Boot repair there is no check-box "Fix MBR"

  • Huh, the first bit is somewhat worrying - did you look at the MBR options tab and make sure the correct drive is selected? (Not sure if you have multiple)

  • MBR options tab is grey and there no check box to enable it. Do I need to create another partition?

  • Okay so I've had a fish through the boot repair report and it's pretty funky, the program see's two windows 7 partitions (which one is the right one?!), but the GRUB OS Prober doesn't see any Windows OSs, I'll see what I can figure out for you...

  • I can't tell the actual settup of your drives from the report, if you run GParted (should be already on the live disk) do you both drives and all their partitions without any "unknown" partition types?

Create a bootable disk / USB using Acronis Disk Director.

Or try free SystemRescueCD.

    Sorry, the OP specifically mentioned that that didn't work.

  • @BenN OP mentions the fixboot parameter which may not necessarily do the same as fixmbr stated here.
