Repair Windows MBR
This tutorial shows how to repair your Windows bootloader (MBR) from Ubuntu dual boot or Ubuntu live DVD/USB. This can be useful if you don't have a Windows DVD on hand.
Boot into your Ubuntu operating system. When you're in Ubuntu, open the terminal and follow the below steps.
Run this command to check your disk:
sudo fdisk -lThe output tells you the disk information:
Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x016c8108 Device Boot Start End Blocks Id System /dev/sda1 * 63 39054014 19526976 7 HPFS/NTFS/exFATNow run these commands to install syslinux, which is a suite of lightweight IBM PC MBR bootloaders for starting up computers with the Linux kernel.
sudo apt update sudo apt install syslinuxOnce installed, you can fix your Windows bootloader by running the below command in the terminal:
sudo dd if=/usr/lib/syslinux/mbr/mbr.bin of=/dev/sda
