I have ubuntu along with windows8. Recently I upgraded to windows8.1. After that I am not getting the grub, which i used to get with windows 8. But i can access ubuntu 13.04 by pressing F9 while starting and in boot options, ubuntu, then i get grub and i can access ubuntu. Files are as usual. I tried to run boot repair but its rectifying this problem.

http://paste.ubuntu.com/6393514 It says, The boot files of the OS now in use-ubuntu 13.04 are far from the start of the disk. Your bios may not detect them. I dont have idea whar it is. Can anyone help on the same?

Boot into the BIOS screen. Check the "Startup Order" tab, there you'll see Windows Boot Loader in position 1.

Change the order so "ubuntu" is in the first position.

I just recovered my partition this way.

On my Samsung Series 9, changing the booting order (promoting "ubuntu" in first position) did not work: the order with the Windows Boot Loader in first position was restored after every reboot.

Here's what worked:

  • Boot into the BIOS setup (F2)
  • Go to Boot --> Boot device priority
  • In the boot priority order, go to "Windows Boot Manager" (which should be in position 1) and disable it (Shift + 1)
  • Save BIOS settings and reboot

You should now have your GRUB menu back, from which you can boot Windows or Ubuntu Linux.

If you can access ubuntu, reinstall grub:

Note than in my example, I have grub installed in the first hard drive. Your installation may be different (sdb for example):

sudo grub-install /dev/sda

If you're not sure which one to use:

sudo fdisk -l

Will show you the devices and partitions you have.

After installing grub, update it:

sudo update-grub

Good luck!
