http://www.linuxandlife.com – MBR (Master boot record) is the default bootloader of Windows. After you install a Linux distro alongside with Windows, MBR will be replaced by the bootloader of the Linux distro (usually Grub or Grub2). If you want to remove the Linux distro out of your computer, the first thing you need to do is to restore MBR. In this article, I will show you some methods to do that: 1 - Use Boot-Repair Boot-Repair is a tool provided by Ubuntu to repair frequent boot issues you may encounter in Ubuntu or other Linux distros like when you can't boot Ubuntu after installing Windows or another Linux distri (Distributions)

Stories similar to How to restore MBR in dualboot system

Hi all, Recently got a new Dell XPS15 laptop. The laptop came with Windows 8 by default (no provided installation media). Have been having some real difficulties with dual booting Ubuntu 12.04 and Windows 8.

Please help me. I'm curious about but VERY new to Ubuntu and Linux in general.

Short: My system has 2 OS: Win 7 x64 and Ubuntu 12.10. I'm getting 2 Windows boot options: "on dev/sda1" and "on dev/sda2". What does this mean?

How to Repair Grub 24 weeks 2 days ago

Yesterday I installed ubuntu 12.04.1.

Note : its a dual boot system along windows 7

At first grub was appearing and i was able to start ubuntu but then i had to switch to windows but windows was not booting when i select windows 7 it jumps back to grub window. So i fix the Windows Boot Loader using repair from windows media and wolla windows started to boot but Ubuntu Grub gone.

I believe I have a "bad" grub2 setup for each time I install a new distro, my PC system fails to boot. Here is my boot info. It appears that grub is installed on all disks (probably my fault of being lazy and just running this tool called boot-repair). I would like to install grub onto only one disk's MBR which is where my linux installation lies.

I'm trying to restore Grub to boot Linux Mint 13 and Windows 7. I just installed Windows 7, which rewrote the MBR, and then I was told I could simply boot Ubuntu live cd, install boot-repair, and reinstall grub over the MBR. I went through the installation, using the option to purge the old grub, but it failed, asking me to run some terminal commands to uninstall grub.

I am a GRUB noob and I would appreciate if you could help me with my issues.

I want to install several GNU/Linux Distros but I broke GRUB so I used boot-repair to fix it. I wanted to have a separated /boot partition on /dev/sda1 containing the following options: /dev/sda5 -> my old Ubuntu 12.04 x64 / /dev/sda6 -> /home for Ubuntu in sda5 /dev/sda10 -> LinuxMint

I first ran the bo

So, I don't know what exactly how I managed to delete the MBR record on windows partition. But let me explain what I did next, I ran the ubuntu boot repair tool and now Windows is not even listed in my grub loader.

So I went and booted with windows cd and choose repair. Then I ran ubuntu boot repair again via live cd. Here is the log http://paste.ubuntu.com/1426181/. Still no luck.

It first started when I deleted my partition that had Ubuntu 12.04 on it. Little did I realize at the time that it would destroy all the resources of Grub on it, and subsequently prevent me booting into my hibernated windows. So I made a 12.10 Ubuntu live USB and reinstalled windows bootloader.

Ok, so I'm having this problem. I have also seen something called Boot Repair

Any help?
