I have recently reinstalled windows 10 in my Ubuntu/Windows dual boot laptop. After that, GRUB bootloader is not loading up. It straight goes booting up the Windows.

I saw a couple of blogs suggesting boot-repair. I did that and it's still not loading. Help.

  • I solved same problem recently in my desktop by reinstalling grub. – BlueManCZ Apr 18 '17 at 17:10
  • It's even not getting mounted on the linux partition. – Souparno Adhikary Apr 18 '17 at 17:15
  • You must boot some live Linux disto and mount your partition manually, install GRUB to it (according to previous link), then reboot computer and GRUB should work. – BlueManCZ Apr 18 '17 at 17:21
  • I exactly did that. Did a boot from a usb stick, used gparted to identify the partition and then tried to mount that. It gives out an error "not a valid partition". – Souparno Adhikary Apr 18 '17 at 17:27
  • Did you try changing the bootloader to grub in the BIOS. – Kishlay Kumar Apr 18 '17 at 17:30

sorry for my bad english! :) it is because when you install windows after linux(ubuntu) the windows loader takes places on the hard disk, to do: It consists of booting thanks to Super Grub2 Disk. Once in your system you will recover GRUB with a simple command. http://www.supergrubdisk.org/ download this file and then boot then in a usb or disk, then boot this from the boot options or bios then in the super grub2 select:

Detect any os your Ubuntu (you have to select it from the list of detected OS) Once you have started in your distribution you will open a console and load the Grub in the MBR by executing the following command:

Grub-install / dev / sda when sda is your hard disk!
